Dragon Ball GT: Final Bout Recompiled

English | Español

Static recompilation for PC of Dragon Ball GT: Final Bout for PlayStation, based on PSXRecomp and recomp-ui.

The original MIPS code is recompiled as native Windows code and integrated into an independent executable with a launcher, mod support and rendering settings. This is not a traditional emulator.

Players	1-2
Platform	Windows x64
Region	USA
Serial	SLUS-00493
Genre	3D fighting
Version	v0.2.1

The game and its data are not distributed. You must provide files from your legally owned copy of Dragon Ball GT: Final Bout.

• This project expects the USA version SLUS-00493.
• See baserom.md for the expected size, serial, volume and checksums.
• Disc images, retail BIOS files and generated C sources are not included.
• The release includes compiled runtimes and native overlay libraries. You supply the disc.

Playing

1. Download dbfb-0.2.1-windows-x64.zip from v0.2.1 experimental release.
2. Extract the package to a Windows folder.
3. Provide your legally owned copy following the identity in baserom.md.
4. Run DBFinalBout_Recompiled.exe or open the included launcher.
5. Keep widescreen disabled for faithful 4:3 presentation, or enable psx.enhancement.widescreen for 16:9/adaptive presentation.

The package is already compiled. Select your own disc on first launch; no build is required. OpenBIOS is included under its MIT license.

Renewed combat (optional, offline)

In Mods, enable Combate renovado for the integrated combat profile. Todos los personajes unlocks all 17 fighters independently. Both default to off. The profile includes input assistance, native aerial follow-ups, movement, defense, hit-stop, ki changes and a slightly wider camera. The new arm recovery transition is limited to verified animation record 0. This remains experimental: flight can still leave a fighter outside the original camera's view; measured move cards and difficulty balance are not exhaustive. See the release notes. Original-mode package tests also exposed an intermittent watchdog exit. v0.2.1 fixes a host-side wait on already-finished autocompile workers, but the cause of every intermittent exit remains open. v0.2.1 is an experimental pre-release.

Recommended Settings

• Renderer: software, as the reference path.
• Widescreen: stretch-only; 16:9/adaptive available.
• Vulkan: available as an experimental option.
• PGXP: separate precision variant included for testing.
• Netplay: LAN/direct-IP available; online ICE/TURN is not enabled.

Building From Source

Main requirements:

• Windows x64.
• Git with submodules.
• CMake 3.20 or newer.
• Ninja or another supported CMake generator.
• Python 3.
• A toolchain compatible with PSXRecomp.
• The legally owned disc described in baserom.md.

git clone --recurse-submodules https://github.com/novapowers0/DB-Final-Bout-Recomp.git
cd DB-Final-Bout-Recomp

git submodule update --init --recursive
./psxrecomp/tools/ci/build_emitters.sh

python3 psxrecomp/psxrecomp_cli.py generate \
  --config game.toml \
  --project-root . \
  --disc "disc/<your-disc>.cue"

cmake -S . -B build-release -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build-release --target psx-runtime

To validate the installation without launching the game:

python tools/verify_offline.py

The contents of generated/ are derived from your disc and must never be committed. Build artifacts and game images are ignored by Git.

Version History

v0.2.1

Maintenance pre-release: fixed a host-side VBlank wait on autocompile workers that had published DONE but had not fully exited, added a controlled regression for that interleaving, and added passive watchdog gap/section diagnostics. 121 project tests passed, both runtimes built, the offline check passed, and an isolated 5/3/2-combat matrix passed. The intermittent original -mode watchdog cause remains open; this release does not claim universal stability.

Framework pins: psxrecomp a51c9aa7 (rework-master).

v0.2.0

Experimental renewed-combat release: integrated optional combat profile, verified arm-recovery transition, wider camera, roster unlock, opt-in Windows sampling, and the compiled Windows package. Two original-mode package tests exited through the watchdog; that intermittent cause remained open.

Framework pins: psxrecomp 835f1902 (rework-master), recomp-ui 0546fbcb, and nested recomp-net 55269a62.

v0.1.1

Maintenance release: refreshed the psxrecomp and recomp-ui submodule pins, rebuilt the setup-host package, and added narrow recovery for a stale cleared IRQ callback. A manual session completed Piccolo vs Goku and proceeded to the Little Goku Super Saiyan fight without a hang. The session logs predate the new callback counter, so they do not establish whether that recovery path ran; this result covers the tested sequence and is not a universal no-hang guarantee.

Framework pins: psxrecomp 7d70880d (rework-master), recomp-ui 01bff947, and nested recomp-net c2338c63.

v0.1.0

First playable and validated release, with the updated runtime, overlay cache, stretch-only widescreen, experimental Vulkan and compiled netplay support.

The original v0.0.1 publication was withdrawn because it was too unstable, with crashes/freezes during menu and fight transitions and insufficient validation to present it as a supported release.
