PCSX2 and xemu both emulate consoles from the same console generation, but they solve completely different problems. PCSX2 recreates Sony’s PlayStation 2, the best-selling console in history with over 3,800 released titles. xemu recreates Microsoft’s original Xbox, a console with a far smaller library but a genuinely different emulation challenge because it runs on modified PC hardware rather than custom silicon. As of September 12, 2026, PCSX2 sits on an active 2.10 development milestone (44% complete, due December 26, 2026) while xemu’s stable build has climbed to version 0.8.136. Both projects post commits nearly every day. Neither one costs a cent.
This comparison breaks down what each emulator actually needs from your PC, how compatible each one is with its target library, how the two projects differ in release philosophy, and which one deserves your time if you only have a modern gaming rig and a stack of old discs (or ISOs) to work through. Search interest backs up the demand: “pcsx2” pulls roughly 40,500 monthly US searches and “xemu” pulls about 8,100, both classified as low-competition keywords, according to DataForSEO keyword data pulled September 2026.

What PCSX2 and xemu Actually Emulate
PCSX2 is a PlayStation 2 emulator for Windows, Linux, and macOS. The PS2 launched in 2000 and shipped roughly 160 million units worldwide before Sony discontinued it in 2013, making it the best-selling home console ever produced. PCSX2 recompiles PS2 machine code (built around a MIPS-based Emotion Engine CPU and a custom Graphics Synthesizer GPU) into instructions your PC’s CPU and GPU can execute directly, then reconstructs the PS2’s unusual rendering pipeline in modern APIs like DirectX 12 and Vulkan.
xemu emulates the original Xbox, the console Microsoft launched in 2001 and discontinued in 2009 after selling around 24 million units. The original Xbox is a fundamentally different emulation target because its internals are closer to a stripped-down PC than a custom console: an Intel Celeron/Pentium III-derived CPU, an Nvidia GPU (essentially a customized GeForce 3), and a modified version of the original Xbox kernel built on Windows 2000 code. That similarity to PC architecture is a double-edged sword. It means xemu can lean on dynamic recompilation techniques that map closely to x86, but it also means the emulator has to replicate Microsoft’s proprietary Xbox kernel calls and DirectX 8-era graphics behavior with total precision, since Xbox games were compiled to expect exact hardware timing.
Both projects are fully open source and hosted on GitHub, and both saw commits land in the days immediately before this article published: PCSX2’s repository shows changes on September 11, 2026 touching the Qt frontend, DirectX 12 support for older Haswell and Broadwell GPUs, and a switch to the newer .slnx build format, while xemu’s project page continues to advertise itself directly as being under “Active Development.”
A Brief History of Both Projects
PCSX2’s origins trace back to 2002, when a small group of developers began reverse-engineering the PS2’s Emotion Engine while the console was still in the middle of its commercial life. Early builds could barely run a handful of homebrew demos, and it took years of incremental progress before commercial games became playable at all. By the mid-2010s the project had matured into one of the most respected community emulation efforts on the internet, and Sony’s own decision to wind down PS2 backward compatibility on later PlayStation hardware only increased demand for a reliable PC alternative. The project moved from SVN to GitHub, adopted the Qt frontend, and has continued shipping numbered releases every year since, with 2026’s development cycle continuing that unbroken streak.
xemu has a shorter but interesting lineage. Original Xbox emulation attempts date back to projects like Cxbx and Cxbx-Reconstruction in the mid-2000s, which made partial progress but never reached broad commercial-game compatibility. xemu itself launched later, built by a different team that took a fresh architectural approach centered on QEMU-style virtualization rather than pure high-level emulation, which is why the project leans so heavily on CPU virtualization extensions today. That architectural choice paid off: xemu reached broad compatibility with far more original Xbox titles in a shorter span of active development than earlier attempts managed across a full decade. The project’s GitHub organization now maintains the emulator alongside supporting tools for BIOS validation and hard disk image creation, reflecting a maturing ecosystem rather than a single standalone executable.

System Requirements: What Your PC Actually Needs
PCSX2 is the heavier of the two emulators in practice, mostly because the PS2’s Graphics Synthesizer is unusually difficult to reconstruct in modern rendering APIs. The GS handled features like emotion-engine feedback effects and specific blending modes that don’t map cleanly onto DirectX or Vulkan, so PCSX2’s GPU plugin has to do extra work to fake that behavior convincingly. In practical terms, that means a mid-range GPU from the last five years (something in the RTX 3060 or RX 6600 class) comfortably handles most PS2 titles at 2x to 4x internal resolution and a locked 60 FPS, but demanding titles with heavy transparency effects or high-poly cutscenes can still push a system, especially if you’re upscaling to 4x or beyond.
xemu is comparatively lighter on the GPU side because the original Xbox’s NV2A chip is architecturally closer to a standard PC GPU than the PS2’s Graphics Synthesizer, so there’s less exotic behavior to fake. The catch is CPU virtualization: xemu benefits from CPU-level virtualization extensions (Intel VT-x or AMD-V) being enabled in your BIOS, and it leans on dynamic binary translation of x86 Xbox code running inside that virtualized environment. A modern quad-core CPU handles this without much trouble, but older laptops that don’t expose full virtualization support to the OS can hit stuttering that PCSX2 wouldn’t necessarily show on the same hardware.

Development Activity and Release Philosophy
The two projects approach releases very differently, and that difference matters if you’re deciding which one to trust for day-to-day gaming. PCSX2 ships large, versioned point releases (the 2.x line) alongside a constant stream of nightly builds for people who want bleeding-edge fixes immediately. Its GitHub milestone tracker shows the 2.10 release targeted for December 26, 2026, with 35 of 79 planned issues closed as of this writing (44% complete), while the 2.8 milestone closed out fully on September 3, 2026. That structure signals a team working against a public roadmap with defined scope for each release, not just shipping whenever something feels ready.
xemu takes the opposite approach: frequent, incremental tagged releases rather than big scoped drops. The project’s GitHub page shows more than 250 releases total, with the current stable build at 0.8.136 (June 2026), following a 0.8.106 release from September 2025. That pace suggests a smaller but consistently active team pushing small improvements out the door quickly rather than batching them into infrequent major versions. Both approaches are valid engineering strategies, but they change what “stable” means in practice. With PCSX2, you can pick a numbered release and expect it to hold steady for months. With xemu, you’re more likely to update every few weeks to pick up compatibility fixes for specific games.
Recent PCSX2 commits from September 2026 include DirectX 12 support extended to older Haswell and Broadwell-generation Intel GPUs when the OS driver stack allows it, an upgrade of the embedded ImGui interface library to version 1.92.9b, and a migration of the Windows build system to the newer .slnx solution format. None of that is flashy from a player’s perspective, but it points to a team still modernizing the emulator’s toolchain rather than just patching game compatibility and calling it done.
Game Compatibility: How Complete Is Each Library?
Compatibility is where the age gap between these two emulation projects really shows. PCSX2 has been in active development since 2002 (originally released as one of the first PS2 emulators ever attempted), and after more than two decades of work, its community-maintained compatibility list shows the overwhelming majority of the roughly 3,800-title PS2 library rated as “playable” or “perfect,” with only a small long tail of titles that rely on obscure hardware quirks still causing trouble.
xemu is younger and working against a smaller library (roughly 990 commercially released original Xbox titles), which sounds like an easier target, but the original Xbox kernel has its own set of proprietary quirks that took years to reverse-engineer properly. xemu’s public compatibility list on xemu.app is actively updated and shows steady month-over-month improvement, with a large and growing share of tested titles marked playable start-to-finish, though a real minority remain stuck at “in-game with issues” or “boots to menu only” while specific kernel calls and audio/video timing edge cases get ironed out.
The practical takeaway: if you’re chasing a specific PS2 game, the odds are heavily in your favor that PCSX2 runs it well today. If you’re chasing a specific original Xbox game, check xemu’s compatibility list before you invest time, because there’s still a real chance you’ll hit a title that isn’t fully playable yet, even though the project has closed that gap significantly over the past two years.
Performance Benchmarks From Independent Testing
Benchmarking emulators is inherently messier than benchmarking native PC games, because performance depends heavily on which specific game you’re running, not just the hardware underneath. That said, patterns from community testing and hardware review outlets converge on a few consistent findings for both emulators.
| Test scenario | PCSX2 result | xemu result |
|---|---|---|
| Mid-range PC (Ryzen 5 / RTX 3060 class), 1x-2x internal res | Locked 60 FPS on the vast majority of tested titles | Locked native framerate (30-60 FPS depending on the game) on most tested titles |
| Same PC, 4x internal resolution upscale | Framerate holds on most titles; transparency-heavy games can dip | Less commonly needed since native Xbox resolution ceiling is lower; upscaling gains are more modest |
| Budget PC (integrated graphics or entry laptop GPU) | Struggles on demanding 3D titles; 2D/lighter titles run acceptably | Generally more forgiving due to lighter GPU-side reconstruction, but virtualization support becomes the bottleneck |
| CPU-bound titles (heavy AI, physics) | Emotion Engine recompilation can bottleneck single-thread performance | x86-to-x86 translation is comparatively lighter weight |
The consistent thread across community benchmark threads and hands-on reviews is that PCSX2 is the more GPU-bound of the two, since it has to reconstruct a genuinely alien graphics pipeline, while xemu is more sensitive to whether your CPU exposes full virtualization support to the operating system. Neither project publishes official first-party benchmark suites, so treat any specific FPS number you see online as a snapshot of one tester’s specific game, build, and hardware rather than a universal guarantee.
Pricing and Total Cost Comparison
Neither emulator charges anything. Both are fully open source under GPL-style licensing, developed by volunteer communities, and distributed free through GitHub and their respective official sites. The real costs sit elsewhere: you need to legally dump a BIOS from a PS2 you own to use PCSX2, and a BIOS/MCPX ROM dump from an Xbox you own to use xemu. Buying a used PS2 for BIOS-dumping purposes typically runs $30-$80 depending on condition and region, while a used original Xbox runs somewhere in the $40-$120 range depending on bundle and controller inclusions, based on current secondhand marketplace listings.
| Cost item | PCSX2 path | xemu path |
|---|---|---|
| Emulator software | Free | Free |
| Console for legal BIOS dump (used, typical) | ~$30-$80 | ~$40-$120 |
| BIOS/kernel dump tooling | Free (community tools + a memory card or modchip route) | Free (community tools; some routes need a modded console or specific exploit) |
| Game files | Rip from owned discs; ROM sites carry legal risk and are not endorsed | Rip from owned discs; same legal caveat applies |
| Recommended PC upgrade (if needed) | $0-$400 depending on current GPU | $0-$250 depending on current CPU/virtualization support |
Neither project sanctions downloading copyrighted BIOS files or game ROMs/ISOs from the internet. Both official projects are explicit that users should dump their own BIOS and game files from hardware and discs they legally own. That’s not a footnote, it’s baked into how each project’s documentation is written, and it’s the only approach this article recommends.
Real-World Use Cases: Who Should Use Which
Five scenarios come up constantly in emulation communities, and the right tool depends heavily on which one describes you.
- You own a stack of PS2 discs and want them playable on a modern PC or Steam Deck-class handheld: PCSX2 is the clear choice. It has the deeper library, more mature compatibility, and better upscaling support for making 2000s-era games look sharp on a 1440p or 4K monitor.
- You specifically want original Xbox exclusives like racing or shooter titles from the early 2000s Xbox Live era: xemu is your only realistic modern option, since there’s no comparably mature alternative actively maintained for original Xbox emulation today.
- You’re restoring a retro game room or arcade cabinet and want both consoles represented: Run both emulators side by side. They don’t conflict, and pairing them alongside something like RetroArch for older systems gives you a genuinely broad retro lineup.
- You’re a developer or modder interested in low-level console architecture: xemu’s codebase is a more approachable entry point into how a stripped console kernel and NV2A GPU worked, since the original Xbox’s hardware is closer to standard PC parts than the PS2’s custom silicon.
- You’re running emulation on a budget or older laptop: Check whether your CPU exposes VT-x/AMD-V properly in the BIOS before committing to xemu. If virtualization is locked or unsupported, PCSX2 with a lower internal resolution setting is often the more forgiving fallback on constrained hardware.
Migration Guide: Moving From Other Emulators or Original Hardware
If you’re coming from an older PS2 emulator setup, a previous xemu build, or straight from original hardware, here’s the practical path to get both emulators running cleanly on a fresh PC.
- Download PCSX2 directly from the official pcsx2.net site or its GitHub releases page, never from a third-party mirror.
- Dump your BIOS from a PS2 you own using a memory card exploit method documented in PCSX2’s official setup guide, then place the BIOS file in PCSX2’s configured BIOS folder.
- Run PCSX2’s built-in setup wizard, which will detect your GPU and recommend a rendering backend (Vulkan or DirectX 12 are the current recommended defaults on Windows).
- Rip your owned PS2 discs to ISO format using a PC optical drive and a tool like ImgBurn, then point PCSX2 at your ISO folder.
- Configure internal resolution under Graphics settings; start at native or 2x and increase only if your GPU headroom allows it without frame drops.
- If migrating save data from an older PCSX2 version, copy your memory card (.ps2) files from the old install’s “memcards” folder into the new install’s equivalent directory before first launch.
- Download xemu from xemu.app or its GitHub releases page for your OS.
- Enable virtualization extensions (Intel VT-x or AMD-V) in your PC’s BIOS/UEFI settings if they aren’t already active; xemu will run noticeably worse without this step.
- Dump your Xbox BIOS and MCPX ROM from a console you own following xemu’s official documentation, then load both files in xemu’s configuration menu.
- Create or download a blank Xbox hard disk image as instructed in xemu’s setup docs, which xemu uses to emulate the console’s internal storage.
- Rip owned Xbox discs to ISO and add them through xemu’s game library interface.
- If migrating from an older xemu build, copy your existing hard disk image and settings file into the new install’s directory to preserve save data and configuration.
- Test controller mapping in both emulators before a long play session; Xbox controllers tend to map most naturally to xemu for obvious reasons, while PCSX2 handles DualShock/DualSense layouts closest to the original PS2 controller feel.
PCSX2 Pros and Cons
Pros: Over two decades of development have produced an exceptionally mature and stable emulator. The PS2 library compatibility is near-complete for practical purposes. Upscaling support lets classic titles look genuinely sharp on modern displays. Active 2026 development continues to add DirectX 12 support for a wider range of GPUs and modernize the interface.
Cons: More GPU-demanding than xemu due to the complexity of faking the Graphics Synthesizer’s rendering quirks. Some titles with unusual effects still show minor visual artifacts at high upscaling factors. Configuration for demanding titles can require digging into per-game compatibility patches.
xemu Pros and Cons
Pros: Lighter GPU footprint since the NV2A architecture is closer to standard PC graphics hardware. Frequent incremental releases mean compatibility fixes reach users quickly. It’s essentially the only actively maintained, modern original Xbox emulator, filling a niche with no serious competition.
Cons: Smaller, younger project with a compatibility list that still has real gaps compared to PCSX2’s maturity. Performance depends heavily on proper CPU virtualization support, which trips up some laptops. Smaller target library overall (roughly 990 titles vs PS2’s ~3,800), so there’s inherently less to play even at full compatibility.
Common Configuration Problems and Fixes
A handful of issues account for most support requests in both communities. In PCSX2, the single most common complaint is graphical glitching in specific games, usually solved by toggling per-game “GS hacks” documented in the compatibility wiki for that title, or by switching rendering backend between Vulkan and DirectX 12 to see which handles a given game’s effects more cleanly. Audio crackling is the second most common issue, typically fixed by adjusting the audio synchronization mode in PCSX2’s sound settings rather than changing hardware.
In xemu, the most common problem by far is a game failing to boot past the Xbox splash screen, which almost always traces back to either an improperly dumped BIOS/MCPX ROM pair or a hard disk image that wasn’t formatted the way xemu expects. The project’s official documentation walks through validating both files’ checksums before troubleshooting anything else. The second most common issue is stuttering during gameplay, which in the large majority of reported cases resolves once virtualization extensions are properly enabled in the system BIOS rather than left in a partially-enabled or OS-blocked state.
# Quick virtualization check on Windows (PowerShell, run as admin)
Get-ComputerInfo -Property "HyperVRequirementVirtualizationFirmwareEnabled"
# On Linux, check if virtualization is exposed to the kernel
egrep -c '(vmx|svm)' /proc/cpuinfo
# A result greater than 0 means virtualization extensions are visible to the OSWhere Each Project Is Headed Next
PCSX2’s public roadmap points toward the 2.10 release due December 26, 2026, with the team already 44% through the planned issue list for that milestone as of this writing. Recent commit history suggests continued investment in broadening DirectX 12 support to older GPU generations and modernizing the build toolchain, both signs of a project planning for long-term maintainability rather than winding down. Given PCSX2 has now been maintained continuously since 2002, there’s little reason to expect that trajectory to change.
xemu’s rapid incremental release cadence (250-plus tagged releases and counting) suggests the project will keep shipping compatibility and performance fixes in small batches rather than large versioned drops. With version 0.8.136 as the current stable baseline and continued active commits, the realistic expectation is ongoing 0.8.x refinement in the near term, with compatibility percentage climbing steadily as more of the roughly 990-title original Xbox library gets tested and patched. Neither project has announced a hard 1.0 milestone, and given how both communities operate, a version number jump matters far less than the compatibility list actually growing.
Interface and User Experience Compared
Day-to-day usability matters as much as raw compatibility numbers for most people setting up an emulation rig, and the two projects have taken visibly different paths here. PCSX2’s Qt-based frontend has been rebuilt from the ground up over the past few years, replacing the older wxWidgets interface with a cleaner settings layout, per-game properties panels, and a built-in achievements system tied to RetroAchievements. The September 2026 commit updating the embedded ImGui library to version 1.92.9b feeds directly into this interface, since PCSX2 uses ImGui for its in-game overlay, performance stats, and debug tools. Anyone who used PCSX2 five years ago and comes back today will notice the settings menus are far more organized, with GS hacks and per-game patches surfaced in a dedicated tab instead of buried in a general options screen.
xemu’s interface is intentionally minimal by comparison. It presents a simple settings window covering display, input, network, and system paths, with most of the emulator’s complexity hidden behind command-line flags or configuration file edits for advanced users. That simplicity is partly a function of scope: original Xbox games have far less variance in the hacks and per-title tweaks needed to run correctly compared to the PS2’s sprawling library, so xemu hasn’t needed to build out the same depth of per-game override tooling that PCSX2 has accumulated over two decades. New users generally find xemu faster to get running for a single game, while PCSX2 rewards the extra configuration time with finer control once you hit a problem title.
Both emulators support RetroArch-style external front-ends for people who want a unified library view spanning multiple systems, though neither one currently ships as an official RetroArch core; you run each as a standalone application and point a launcher like Playnite or LaunchBox at the executable if you want them integrated into a broader library alongside NES, SNES, or PS1 titles.
Handheld PC and Steam Deck Performance Notes
Handheld gaming PCs running SteamOS or Windows have become a major destination for both emulators, since a locked 60 FPS PS2 or original Xbox game looks and feels dramatically better on a 7-inch to 8-inch handheld screen than it did on a CRT in 2002. PCSX2 runs natively on Linux, which means SteamOS-based handhelds get first-class support without needing a compatibility layer, and community testing on Steam Deck-class hardware (a custom AMD APU roughly comparable to a low-power Ryzen chip with RDNA2 graphics) shows the bulk of the PS2 library holding a stable 60 FPS at native or 2x internal resolution, with only the most demanding late-generation PS2 titles requiring users to drop upscaling back to native resolution to maintain a locked frame rate.
xemu also builds for Linux, so it runs on the same handhelds, but its dependency on exposed CPU virtualization extensions becomes more relevant on ARM-based or heavily power-limited handheld chips where firmware doesn’t always expose VT-x/AMD-V cleanly to the OS. On x86-based handhelds like Steam Deck, ROG Ally, or Legion Go, virtualization is typically available and xemu performs comparably to a similarly specced laptop. On ARM-based Android handhelds running Linux compatibility layers, xemu is a much rougher experience today, and PCSX2 is the more realistic choice for that hardware class until xemu’s ARM support matures further.
Community Resources and Where to Get Help
Both projects run active Discord servers and GitHub issue trackers where users report compatibility problems and maintainers respond directly, which is a meaningfully different support model than paid software with a ticketing system. PCSX2’s larger, older community means a much bigger back catalog of forum threads, wiki pages, and per-game configuration guides accumulated over more than two decades, so a Google search for a specific PS2 title’s problems usually surfaces multiple solved threads. xemu’s community is smaller and younger, but it’s tight-knit and its GitHub issues tend to get direct maintainer attention quickly given the project’s high commit frequency; the tradeoff is there’s simply less historical documentation to search through for niche problems, since the project has existed in its current actively-developed form for a shorter span of time.
Neither project sells support contracts or offers paid tiers of any kind, which is worth restating given how much of the broader emulation space has drifted toward Patreon-gated builds in recent years. Both PCSX2 and xemu keep their full feature set, including the newest nightly builds, available to anyone for free directly from their official GitHub repositories.
Legal Considerations for PS2 and Xbox Emulation
Emulator software itself is legal in the United States and most jurisdictions, a point repeatedly upheld in court cases involving console emulation going back to the Sony v. Connectix case over the original PlayStation. What isn’t legal is downloading BIOS files, game ROMs, or ISOs that you don’t have the right to possess. Both PCSX2 and xemu’s official documentation is explicit that users should dump BIOS and game files only from hardware and discs they personally own. Following that path, using a legally-owned PS2 or Xbox console and your own game discs, keeps you entirely within the bounds of established fair-use precedent for personal backups and format-shifting. Downloading pre-made BIOS packs or ROM sets from third-party sites carries real legal risk and isn’t something either project or this article recommends.
The Verdict: PCSX2 vs xemu
These two emulators aren’t really direct competitors, they’re complementary tools solving different console emulation problems, which is exactly why so many retro PC gaming setups run both side by side. If you had to pick just one based purely on data, PCSX2 wins on maturity: a compatibility rate covering the overwhelming majority of a roughly 3,800-title library, more than two decades of continuous development, and active 2026 commits adding modern rendering API support. xemu wins on being the only realistic option in its category: there’s no other actively maintained, modern emulator that gives you access to original Xbox exclusives, and its 250-plus release history and steadily climbing compatibility numbers show a project still closing the gap on a genuinely harder reverse-engineering problem.
The practical answer: install PCSX2 first if you’re building a general-purpose retro PC gaming setup, since it covers far more ground. Add xemu specifically when you want original Xbox titles that never made it to other platforms. Both are free, both are under active 2026 development, and both require nothing more than hardware and discs you already own to use legally.
Frequently Asked Questions
Is PCSX2 or xemu better for a low-end PC?
PCSX2 tends to be more GPU-demanding because of how complex the PS2’s Graphics Synthesizer is to reconstruct, while xemu is comparatively lighter on the GPU but depends heavily on your CPU properly exposing virtualization extensions (VT-x/AMD-V). On a genuinely low-end machine, PCSX2 running at native or 1x internal resolution is often more forgiving than xemu on hardware with poor virtualization support.
Do I need to own the original console to use these emulators legally?
Yes. Both PCSX2 and xemu require you to dump a BIOS (and, for xemu, an MCPX ROM) from hardware you own, and to rip games from discs you own. Downloading these files from third-party sites is not something either official project supports or recommends.
Can PCSX2 run PS2 games at 4K resolution?
Yes, PCSX2 supports internal resolution upscaling well beyond the PS2’s native output, and many users run games at 4x internal resolution or higher, which maps to well above 4K on many titles. Performance at that scaling depends heavily on your GPU and how graphically demanding the specific game is.
Why is xemu’s game library so much smaller than PCSX2’s?
It reflects the source consoles, not the emulators. The original Xbox launched with roughly 990 commercially released titles over its lifetime, while the PS2 had around 3,800 due to its far larger install base and longer commercial life (2000-2013 versus 2001-2009).
Is xemu compatible with Xbox Live-era online features?
xemu focuses primarily on local single-player and local multiplayer emulation rather than recreating the original Xbox Live network infrastructure, which Microsoft shut down in 2010. Some community projects target reviving specific Xbox Live functionality separately, but that isn’t xemu’s core focus.
Which emulator updates more often, PCSX2 or xemu?
xemu has a higher raw release count, with more than 250 tagged releases reflecting a frequent incremental release strategy. PCSX2 ships fewer numbered versions but maintains constant nightly builds between major releases, so both projects effectively update continuously even though their public versioning looks different.
Can I run both PCSX2 and xemu on the same PC without conflicts?
Yes. They’re independent applications with separate configuration folders, BIOS requirements, and game libraries. Running both on the same machine is common among people building broad retro PC gaming setups.
Do either PCSX2 or xemu support Steam Deck or other handheld PCs?
PCSX2 runs on Linux, which makes it compatible with SteamOS-based handhelds like Steam Deck, and many handheld users run it through Linux-native builds or compatibility layers. xemu also supports Linux, though its virtualization dependency means performance on ARM-based or lower-power handhelds can vary more than on a standard x86 gaming PC.
