The game's original code was translated into native code ahead of time, so it runs at modern resolutions, frame rates and aspect ratios while playing exactly like the original.

You need your own copy of the game. No game data is included. Repocalypse reads everything from a disc image you dump yourself: Apocalypse (USA), SLUS-00373.

Features

Up to 4K resolution
Anti-aliasing: supersampling, MSAA and FXAA
High fps: native 60 fps support at the engine level, and interpolated 75, 90 and 120 fps on top
Aspect ratios: 4:3, 16:9, 16:10, 21:9 and 32:9
Native GTE: a native renderer with full floating-point precision for every polygon, effect and shadow, exact and perspective-correct textures, and a depth buffer, on OpenGL and Vulkan backends
Controls: keyboard and mouse added, plus full XInput controller support, with full rebinding for both, with low input lag
Draw distance: reworked to support a much larger draw distance than the original
Asset replacements: support for custom textures and FMV replacements
Saving: autosave at every checkpoint, and memory card saves compatible with emulators
One-liners: subtitles for the voice lines, printed on screen with effects
Cheats: added a dedicated new menu for in-game cheats
Cosmetics: CRT filter, the game's own font at any size, FPS counter, sound filter
Extras: chapter select, save states

Install

Download the latest release for your system from Releases and unzip it anywhere.
Put your disc image in assets/image/: its .cue and .bin files (any names), or only the .bin files.
Run repocalypse.exe (Windows) or repocalypse (Linux).

Saves and settings.ini are kept next to the program.

Steam Deck: use the Linux build, add repocalypse to Steam as a non-Steam game and play in Game Mode.

Optional extras

Folder	What goes in it
`assets/replacements/textures`	HD textures and full-screen pictures
`assets/replacements/fmvs`	HD movies (`INTRO.mp4`, `SEWER.mkv`, ...) that play instead of the disc's

HD texture pack: download it from either mirror and unzip it into assets/replacements/textures assets/replacements/fmvs. Turn it on or off in Recomp Enhancements -> Performance.

Problems?

Ask on Discord.
Attach debug/repocalypse.log (and any debug/crash_*.log) from the game folder.
An error on first start almost always means the disc image is missing or wrong: check that the .bin files are in assets/image/ and are a dump of the USA version.
