Pokémon Emerald (mstan)

Game: Pokémon Emerald Version → (GBA, 2004)

Static recompilation of Pokémon Emerald for Windows, Linux, and Android with gbarecomp. The ROM’s ARM7TDMI code is translated to C, and the console’s real BIOS is recompiled and run too; code the recompiler didn’t cover runs through an interpreter the first time, is compiled to native code, and is saved for later launches. It gets into gameplay, though its author still presents it as a preview. From the pret/pokeemerald decompilation it only takes function names and addresses, not its code. Since 0.1.0 it has two-player netplay, over the internet or LAN, with input delay or rollback: each machine simulates both consoles and the link cable, which has been play-tested; 0.1.1 added the Wireless Adapter for the Union Room, still experimental, with no trades or battles verified that way. It also has an experimental overworld widescreen mod (fit to window, 16:9, 21:9, or 32:9, portrait included) that shows more scenery and characters, another mod that makes the in-game clock follow your computer’s time, and, on Android, its own touch controls: tap to walk, draw a path with your finger, or pick moves directly in battle. Version 0.1.2 came out on October 18. 31 of its 74 commits list Claude as a co-author.

You needYour own US Pokémon Emerald ROM (SHA-1 f3ae088181bf583e55daf962a92bb46f4f1d07b7) and a dump of your Game Boy Advance BIOS. Plus 64-bit Windows, x86-64 Linux, or Android 9 or later on ARM64. For netplay, both players need the same recomp release and the same ROM.
