Budokai, Budokai 2 and Sagas, each running as its own native core. A hybrid core between recompilation and decompilation, not emulation. All three on Linux (Ubuntu 26.04 for now), Windows and Android, now joined by Supersonic Warriors on Game Boy Advance as a statically recompiled native port. One launcher. HD rendering. Online play.

Native. Not emulated.
The Nimbus Recompilation Project (TNRP) runs on a hybrid core that sits between recompilation and decompilation. Each game gets its own native core, and those cores run on a shared Nimbus host and renderer. There's no Dolphin, no emulator and no interpreter emulating the hardware. Every game can be played in Original or Remastered mode, and crossplay has been tested across Linux, Windows and Android. Detailed architecture notes are coming to the site later.
What you get is a standalone game that starts like any other app, renders through a modern GPU pipeline and is built to outrun emulation, with headroom left over for higher resolutions and HD assets.
- One build for the whole trilogy, one launcher
- Your own legally obtained disc, nothing else
- Keyboard, mouse and gamepad out of the box
Five games. One launcher.
All three GameCube releases (NTSC-U), each ported on its own and all started from the same launcher. Game Boy Advance has joined too: Supersonic Warriors is out now as a native port (from Alpha 1.4), and Taiketsu is out now in Alpha 1.5.

Also in Alpha 1.5
New in Alpha 1.5
One launcher. Every mode.
One window for the whole trilogy. Pick a game, see its status at a glance (ready, no disc, no core) and choose how to play. Keyboard, mouse or gamepad all work, with a CRT filter on top.
- PLAYStart the game, solo.
- HOST GAMEGet a join code to share with a friend.
- JOIN GAMEPaste the code and you're in. Recent hosts are remembered.
- LOCAL 2 PLAYERSTwo pads, one screen.
Online play
Play over your LAN, or online with a short join code. After each session the launcher shows how it went, including the other player and ping. Sagas plays as two-player co-op; Budokai and Budokai 2 play head-to-head.
Under the hood
The same engine room powers every game in the trilogy.
Nimbus GX Renderer
A modern graphics backend built on Aurora, WebGPU (Dawn) and SDL3. It recreates the GameCube's graphics on today's GPUs.
Nimbus Host
The shared host layer for windowing, input, audio, saves and online play, so each port can stick to the game itself.
Nimbus Core
The game code in each core: the original game logic, carried over into a native core.
Nimbus Port Kit
The tooling that turns a disc into a standalone build, reused across all three games.
HD everything
Higher internal resolutions, AI-upscaled texture packs for all three games and HD movies for Sagas. Grab them in Downloads.
Built to outrun emulation
No emulator overhead means more headroom. In Sagas benchmarks on the dev laptop, the native build ran faster than Dolphin at both 1× and 5× internal resolution.
Platforms
Where things stand right now. Alpha 1.5 is out for all three platforms (2026-11-05); it's an early alpha, and work continues.
Linux
Alpha 1.5The main development platform. The three GameCube games plus Supersonic Warriors and Taiketsu are in one build. Ubuntu 26.04 (64-bit x86) is the supported distro for now; other distros aren't supported yet.
Android
Alpha 1.5The three GameCube games, Supersonic Warriors and Taiketsu run on Android 13+, in one arm64 app. Sagas runs comfortably above full speed on handhelds such as the Retroid Pocket 5 and the RG Slide.
Windows
Alpha 1.5The three GameCube games, Supersonic Warriors and Taiketsu run natively on Windows, in one portable x64 folder with the same launcher, host and renderer as Linux and Android. Tested on Windows 11 x64; it needs an AVX2-class (x86-64-v3) CPU and a Vulkan or D3D12 GPU. Sagas two-player co-op isn't fully covered on Windows yet.
Benchmarks
Early dev resultsEarly numbers from current Android dev builds, measured on real hardware and shown with the core they were measured on, next to Dolphin on the same device. Results vary by device and game: on the RG Slide, Nimbus is behind Dolphin in all three games, while on the Pixel 9a it ties in Sagas, is slightly ahead in Budokai and is behind in Budokai 2. Closing the gaps is ongoing work. Linux and Windows results are coming.
Loading the benchmark readout…
How we test: Method TBD. We'll publish the test scenes, settings and capture method alongside the first results.
Submit your results — coming soonOnline. Across platforms.
Cross-platform online play with an online lobby, join codes, a growing global server fleet and tournaments on the way.
Crossplay
Linux , Android and Windows
An Ubuntu PC, a Windows PC and an Android handheld can join the same match. Crossplay is tested on real hardware, including Budokai 2 and Sagas between a Linux laptop and a Retroid Pocket 5.
How you find each other
Join code
TestedHost online and you get a short join code. Share it with a friend, they type it in, and you meet in the same match. Codes use clear characters so they are easy to read aloud.
LAN
TestedHost on your home network and the other player can join from the same LAN. The launcher remembers recent hosts.
Quick match & public games
The online lobby pairs you with someone on the same game and build, or lists public games anyone can join. It's in the Android app now, and coming to the Linux and Windows launchers too.
Tournaments
In developmentSingle-elimination brackets for 4 to 32 players, best of 1, 3 or 5, with byes, forfeits and organizer rulings. Supported on the online side and coming to every platform: Linux, Windows and Android. No launcher has the screens yet.
What a match looks like
Same game, same build
Before a match starts, both sides check that the game, build and settings match. The joiner plays with the host's unlocks for that session, and their own save isn't touched.
Co-op & versus
Sagas is two-player co-op: player 2 presses START to drop in. Budokai and Budokai 2 are head-to-head. Up to 4 controllers are supported across the two devices (so far we've tested one controller per device). You can see ping in-game.
Regional servers
TestedOnline play runs on city-based servers: Memphis, San Francisco, New York, Amsterdam and London are live now, and Alpha 1.6 expands the fleet to sixteen instances across North America, South America, Europe, the Middle East & Africa and Asia-Pacific. Pick a location in the launcher, or leave it on Auto for the lowest ping. See the global map.
Self-hosting
Not yetSelf-hosted servers aren't available yet. There's also no spectator mode or chat right now.
Server regions
The fleet has grown to 16 server instances worldwide in preparation for Alpha 1.6 and beyond. Explore the interactive map up top: Global server fleet.

What's new in Alpha 1.5 Released 2026-11-05 for Linux, Windows and Android
Released 2026-11-05 for Linux, Windows and Android. Android installs over the existing app and keeps your links, settings and saves.
Earlier notes Hotfixes & prior alphas
Supersonic Warriors is here
New- Dragon Ball Z: Supersonic Warriors (Game Boy Advance) joins the launcher on Linux, Windows and Android.
- It's a true native port: the game's program is statically recompiled into its own game module. No emulator, no interpreter.
- Nimbus draws the picture itself through the same shared renderer as the GameCube games, so it can go far beyond the original resolution.
- Bring your own Supersonic Warriors (USA) ROM and link it on the Z Capsules page.
Fight your friends
New- Online multiplayer across Linux, Windows and Android, with your ping shown on the HUD.
- Quick Match with automatic results: both players see the knockout and the winner is reported. If a fight ends on time-out, the launcher asks who won.
- Link VS: two linked consoles in one app, with Team Select, fights, Quick Match, Local Two Players and save states.
HD all the way up
New- Internal resolution from 1x up to 8x.
- HD texture packs with 1x–4x tiers. In the F1 menu, Texture pack resolution picks Auto or a tier.
- With the full HD pack at 8x, fights run at a steady 60 fps on the Retroid Pocket 5.
- Three pack downloads: PC, Android and a small 2x lite pack.
Online fixes
Fixed- When you join a match, your controller now drives your own fighter.
- The host's game window opens while waiting for the other player, so you can see it's waiting.
- In online Link VS, each player sees and hears their own console.
- Hotkeys (F1–F7, Esc) act once per press: holding a key no longer re-triggers save states or toggles.
Known limitations
Honest notes- Timing uses a provisional model: in busy moments the game can run about one frame early compared with the original, and some sound timing differs. Both players in a match always stay in sync with each other.
- The Supersonic Warriors module is still development-qualified, so online play uses its one approved version.
- Link VS on a single device shows one console at a time (you can switch), not two screens.
- Performance figures are from the Retroid Pocket 5; the RG Slide wasn't measured for this release.
Previous releases
Alpha 1.3 · 2026-11-02
London and Amsterdam servers joined the menu; the fleet has kept growing toward Alpha 1.6.
New servers in Europe
New- London and Amsterdam join the US servers (Memphis, San Francisco and New York) on Linux, Windows and Android — the start of today's wider global fleet.
- Auto picks the region with the lowest latency, and you can still choose one yourself.
- The menu still works with keyboard, gamepad and touch. See the global server map.
Smooth upgrade
Automatic- If you use the stock server list, it upgrades automatically.
- Custom server lists, settings, saves and linked files are kept.
- Install the full 1.3 download to get the new server menu. The standalone modules are unchanged.
How matches connect
Unchanged- Quick Match and public rooms use the online lobby. Private join codes skip the lobby.
- Your game runs on your own device. Online play uses Nimbus regional servers.
- Auto still works with players on earlier versions. To pin a match to London or Amsterdam, both players need Alpha 1.3.
Alpha 1.2 · 2026-11-02
Quick Match in Budokai and Budokai 2 starts at character select with every fighter unlocked.
Quick Match, straight to the fight
New- In Budokai and Budokai 2, Quick Match now drops you right at the 1P-vs-2P character select with every fighter unlocked.
- There's no separate Quick Versus menu item: it's simply how Quick Match starts now.
- Local Two Players uses the same unlocked setup.
- Tournament, public rooms and manual host/join start the same way as before. Sagas is unchanged.
Your saves stay yours
New- Each quick start uses its own separate session memory card, so your regular saves aren't touched.
- Normal Play keeps using your regular card.
- The two unlocked memory-card seeds and the quick-start states are intentionally bundled in the downloads. No disc images, other personal saves, source files or signing keys are included.
Friends on older versions
Compatible- Mixed Alpha 1.0, 1.1 and 1.2 matchmaking still works. Whoever hosts decides how the match starts: a 1.2 host starts at the unlocked character select, and an older host uses the original start.
- No need to split players up by version. The usual core compatibility requirements still apply.
- Install the full 1.2 download to get these launcher changes. Updating only the host module doesn't add them to an older launcher.
Alpha 1.1 · 2026-11-02
Android touch polish, the Sagas outline fix and Components versions & rollback.
Android touch controls
New- Cleaner, translucent GameCube-style buttons with clearer labels and visible feedback when you press them.
- Shoulder buttons sit below the performance overlay, START is a wider pill, and the D-pad has arrows.
- Buttons respond to their drawn shapes, with a little thumb margin. New touch-opacity slider (30–90%) and a small stick dead zone.
- The four-star Dragon Ball menu button has an amber finish, and dragging it no longer opens the menu by accident.
- Touch controls hide automatically when a gamepad is connected (the menu ball stays). You can still show or hide them yourself.
Sagas outlines
Fixed- Black character outlines no longer disappear during projectile and explosion effects, including in co-op.
Components: versions & rollback
New- New Components > Versions / rollback screen on Linux, Windows and Android.
- See whether each part is bundled or replaced, its signed version label where available, and its exact fingerprint.
- Your previous selection is kept. Rollback brings it back and Restore bundled returns to the stock parts; both apply the next time you launch a game and don't touch saves or linked files.
- A damaged previous file is rejected without changing what's active.
- Alpha 1.4 · 2026-11-03 · full notes: RELEASE-NOTES.txt (hotfixes through 8). Downloads remain under the Alpha 1.5 cards as alternates.
- Alpha 1.3 · 2026-11-02 · full notes: RELEASE-NOTES.txt. Downloads and SHA-256 checksums stay available under Other versions on each Main distro card.
- Alpha 1.2 · 2026-11-02 · full notes: RELEASE-NOTES.txt. Downloads and SHA-256 checksums stay available under Other versions on each Main distro card.
- Alpha 1.1 · 2026-11-02 · full notes: RELEASE-NOTES.txt. Downloads and SHA-256 checksums stay available under Other versions on each Main distro card.
- Alpha 1.0 · 2026-11-01 · the first public release for Linux, Windows and Android. Its downloads and checksums are also under Older alphas.
Main distro
Launcher + all stable modules, bundled in one. Alpha 1.5 is out for Linux, Android and Windows (released 2026-11-05) and adds Taiketsu. Runtime components for all five games are bundled; no game files are included, so you need your own NTSC-U discs and your own Supersonic Warriors (USA) ROM. Third-party license notices ship inside every download.
Bundles: launcher · hosts shared-20261102 and agb-host-r3 · renderer v601-shared · cores for all five games

Also on GitHub Releases. Looking for Alpha 1.3, 1.2, 1.1 or 1.0? They're under Other versions on each card and in Previous releases.
HD packs
Optional HD texture and movie packs for each game. They need the native Nimbus build and your own disc (or, for Supersonic Warriors, your own ROM). The Windows build uses the same shared pack loader as Linux, so the same packs apply there; we haven't run one on Windows yet.
Loading the pack list… If nothing shows up, open packs.json directly.
Checking a download
On Linux run sha256sum FILE; on Windows run certutil -hashfile FILE SHA256. The result must match the SHA-256 shown on the card. Each pack is a single zip.
About The Nimbus Recompilation Project (TNRP)
Free. No catch.
FreeEverything here is free: the native builds, the modules, the HD packs and online play. There's no price, no paywall, no premium tier, and we don't take donations.
Closed source, for now
Open source plannedThe Nimbus Recompilation Project is custom built for these three games, and we plan to make it open source. It isn't open source yet because of:
- Server hosting: we run the online servers.
- Networking: keeping online play secure and stable.
- Cross compatibility: keeping the Linux, Windows and Android builds matched so crossplay works.
- Continued, focused development: keeping the work concise and moving.
We also plan to release a mature toolset in the future.

FAQ
What is TNRP?
TNRP is short for The Nimbus Recompilation Project, the new name of The Nimbus Project: free native ports of Dragon Ball Z Budokai, Budokai 2 and Sagas (GameCube) and Supersonic Warriors and Taiketsu (Game Boy Advance) for Linux, Windows and Android, with online crossplay. The official site is nimbusrecomp.org.
Is TNRP an emulator?
No. TNRP runs on a hybrid core that sits between recompilation and decompilation. Each game gets its own native core, and those cores run on a shared Nimbus host and renderer. Dolphin isn't involved, and there's no emulator and no interpreter emulating the hardware. Supersonic Warriors (GBA) is a native port too: its program is statically recompiled into its own module. Detailed architecture notes are coming to the site later.
Do I need my own copy of the game?
Yes. No disc images included; your own NTSC-U discs are required. Bring your own legally obtained disc of Budokai, Budokai 2 or Sagas, and the launcher shows NO DISC until it finds one. For Supersonic Warriors, bring your own USA ROM.
Which versions are supported?
The North American (NTSC-U) GameCube releases of all three games. Dragon Ball Z: Supersonic Warriors for Game Boy Advance (USA ROM) is supported from Alpha 1.4. Dragon Ball Z: Taiketsu (USA ROM) is supported from Alpha 1.5.
Can I play with a friend online?
Yes. Host a game from the launcher, send your friend the join code and they join over your LAN or online through Nimbus. Sagas is co-op; Budokai and Budokai 2 are versus. Local two-player works too.
Which Linux distros are supported?
Ubuntu 26.04 (64-bit x86) for now. Other distros aren't supported yet.
Will it run on my handheld?
The Android build runs the three GameCube games and Supersonic Warriors and needs a 64-bit (arm64) device running Android 13 or later. Sagas runs above full speed on handhelds like the Retroid Pocket 5 and RG Slide.
What are the HD packs?
Optional downloads that swap in AI-upscaled textures (all three games) and upscaled movies (Sagas). They work with the native builds only, and you can switch back to the originals from the F1 menu at any time. See Downloads.
Does TNRP cost anything? Is it open source?
It's free: the builds, the HD packs and online play, with no paywalls and no donations. The Nimbus Recompilation Project is closed source for now, and we plan to make it open source. It isn't yet because of server hosting, networking, cross compatibility and keeping development focused; we also plan to release a mature toolset in the future. See About the project.
When is it coming out?
It's out. Alpha 1.5 came out on 2026-11-05 for Ubuntu 26.04, Windows 11 (Vulkan or D3D12) and Android 13+ (arm64) and adds Taiketsu (with Supersonic Warriors from 1.4); the current release is Alpha 1.5 (2026-11-05). It follows Alpha 1.3, 1.2 and 1.1 on 2026-11-02 and Alpha 1.0 on 2026-11-01. Get it from Main distro. It's an early alpha; follow the roadmap above for what's next.

Map data
The coastlines in our global server map come from Natural Earth (1:110m land), free public-domain map data.

No disc images or game data are distributed. You need your own NTSC-U discs.
The Nimbus launcher, host, renderer and core tooling are our own original code.
Modules
The hosts, renderer and the game cores (three GameCube cores plus Supersonic Warriors) are also available on their own, signed, for each platform. You don't need them to play: the main distro already bundles everything and automatically selects its bundled cores. Swap a part from the launcher's Components menu without reinstalling. The launcher itself only updates through the main distro.
Module set 1.5: new Taiketsu core BDBE70 agb-native-r1, GBA host agb-host-r4 and renderer v602-shared · the Supersonic Warriors core, host shared-20261102 and the three GameCube cores unchanged · catalog.json
Loading the module list…
Installing a module:
- Android: select the
.nimbus-componentfile directly in Components. - Linux and Windows: extract the ZIP and keep the binary next to its
.ticketfile, then select it in Components. - Changes apply the next time you launch a game. Nimbus doesn't download or update modules automatically, and parts can't be swapped mid-game.
- Rollback (Components > Versions / rollback) restores your previous selection, and Restore bundled goes back to the stock parts. It isn't an automatic recovery system.
- Use only the files for your platform: each one has its own SHA-256. Standalone Linux core modules need an x86-64-v3 CPU; on older (baseline) CPUs, stick with the cores bundled in the main distro.
- Module version labels (for example
c19a6-bolt,agb-native-r1orv601-shared) are separate from the distro version. Online play is limited to reviewed cores; other cores still work offline.
