GTA Advance Native

An experimental Windows native recompilation of the USA (BGTE) edition of Grand Theft Auto Advance, with a higher-resolution scene renderer and camera controls.

Development snapshot — October 18, 2026. This is not a finished full-game port.

Download and run

Download the Windows preview archive from this repository's Releases page, extract it, and follow the included START-HERE.txt. Supply your own USA ROM and GBA BIOS in the assets folder. Neither file is included.

The main preview offers Original, 720p, 1080p, 1440p and 4K resolutions, Original/60/120 presentation options, and 1.00x/0.75x/0.50x/0.25x zoom. Rendering preserves the original aspect ratio; the 4K scene is 3240 × 2160 inside the selected display.

The preview's 120 setting repeats frames. True 120 FPS motion and consistent frame pacing remain unfinished. The latest development source includes experimental temporal rendering, but its most recent build and timing test failed. It has not replaced the playable preview.

What is here

• gta-native/: game integration, renderer, tests and baseline generated C++.
• generated/: native gameplay and RAM-code variants used by the completed preview builds.
• runtime-overlay/: current modified runtime source files, applied over the pinned GBARecomp dependency.
• ui-overlay/: current launcher/runtime UI files, applied over the pinned UI dependency.
• scripts/: dependency preparation and source-check scripts.
• docs/STATUS.md: verified results and known limitations.
• docs/BUILD.md: build layout and dependencies.

Generated C++ translates code from the user-supplied game. The game executable still requires the original ROM for assets and data. No ROM image, BIOS image, save state, user save, credentials, local compiler installation or capture dump is included.
