Dragon Ball Z: The Legacy of Goku II Recomp

Dragon Ball Z: The Legacy of Goku II Recomp

Experimental preview. This recompilation is a byproduct of developing gbarecomp: the games are the proving ground, while the reusable framework is the larger goal. This is not a finished commercial port, so expect rough edges and please report problems. For more context, read Recomp + AI: 5 Months Later ».

Static recompilation of Dragon Ball Z: The Legacy of Goku II for Windows, with an optional Adaptive Widescreen mod.

The game ROM and Nintendo GBA BIOS are not included. You must provide your own legally obtained dumps.

Status

The USA release boots through its attract sequence and into gameplay. Its strict-static validation covers attract mode, gameplay, and a 6,000-frame traversal fuzz route without interpreted instructions or missing dispatches. The initial v0.0.1 build is an experimental preview and has not been exhaustively tested through the entire game, so back up important saves.

Quick start

1. Download the Windows zip from Releases and extract it.
2. Run DragonBallZLegacyofGokuIIRecomp.exe.
3. In the launcher, select your Dragon Ball Z: The Legacy of Goku II (USA) ROM and retail GBA BIOS.
4. Configure display, audio, controls, and mods, then select Play.

The launcher remembers valid files after the first setup. Enable Skip launcher on boot if you want later launches to go directly into the game.

Included mod

Legacy of Goku II Adaptive Widescreen is optional and disabled by default. It expands the HUD and overworld as the window is resized, up to a 480×160 logical view, using authored 64×64-tile field planes and widened actor visibility. It does not stretch the original image or change camera and world coordinates.

The faithful 240×160 output remains pixel-identical with the enhancement disabled. Open the launcher's Mods page to enable it.

Features

• Native Windows x64 application
• ROM and BIOS setup through the shared recomp-ui launcher
• Optional Adaptive Widescreen mod with edge-anchored HUD placement
• Keyboard and modern game-controller support
• Windowed and fullscreen play with sharp scaling and optional affine filtering
• In-game settings menu
• Cartridge saves and save states

Controls

GBA control	Keyboard
D-Pad	Arrow keys

Use Shift+F1-F9 to save a state and F1-F9 to load one. Controls can be changed from the launcher.

Building from source

Windows development requires CMake, Ninja, MSYS2 MinGW64, and SDL2:

git clone --recurse-submodules `
  https://github.com/mstan/DragonBallZLegacyofGokuIIRecomp.git
cd DragonBallZLegacyofGokuIIRecomp

cmake -S gbarecomp -B gbarecomp/build -G Ninja
cmake --build gbarecomp/build --target gba_recompile
pwsh tools/regen.ps1
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build --target DragonBallZLegacyofGokuIIRecomp

Generation requires the supported ROM revision and a retail GBA BIOS. Their identities and local development paths are documented in baserom.md and game.toml. ROM-derived generated code, copyrighted inputs, saves, and build output remain local and are never committed.

Contributors can run the validation scripts under tools/ and pwsh tools/make_release.ps1 -Version 0.0.1 to build a sanitized Windows package.
