Pokémon Sapphire Version

Gen1Recomp

bryanthaboi/gen1recomp

A native Lua/LÖVE recreation of the first three generations of Pokémon: Red, Blue, Yellow, Gold, Silver, Crystal, FireRed, LeafGreen, Ruby, Sapphire, and Emerald. Despite the name, it no longer stops at the first generation. The engine and map behavior are hand-written; the game data and graphics are decoded from a ROM the player supplies. It’s a recreation, not a static recompilation. There are Windows, macOS, Linux, Android, and iOS builds, among others. Beware: the gen1recomp.com website isn’t the project’s, and its author asks people not to download anything from it.

Pokémon Ruby / Sapphire (mstan)

mstan/RubySapphireRecomp

Static recompilation of Pokémon Ruby and Sapphire for Windows with gbarecomp, with a separate executable and download for each game. The ROM’s ARM7TDMI code is translated to C, and the console’s real BIOS is recompiled and run too. Both games boot and get into gameplay, but its author presents it as an early preview and warns that, as the oldest Generation III engine, it should have a few more boot, save, and clock quirks than their FireRed and Emerald recomps. Code the recompiler didn’t cover runs through an interpreter the first time, is compiled to native code on the fly, and is saved to disk for later launches. From the pret/pokeruby decompilation it only takes function names and addresses, not its code. It has a pre-boot launcher to pick the ROM and BIOS and set up video, audio, and controls, save states, and an optional Absolute RTC mod that makes the in-game clock follow your computer’s time. Version 0.0.5 (October 18) updated the engine and launcher. 15 of its 28 commits list Claude as a co-author.
