What you need: A dump of Kingdom Hearts: Chain of Memories for the Game Boy Advance from your own cartridge: the European (B8CP), US (B8CE) or Japanese (B8CJ) version. The launcher checks it by SHA-1.
SHA-1 of a correct dump:
- Europe (B8CP): `8db73586cdb11b3795907edebf43228dbcd3e6b2`
- USA (B8CE): `10729bd884f8fdca7a310b6d606c52e46657aa48`
- Japan (B8CJ): `59ec0a0a4ccd1e6acb3bbd7bfb21d63988958cfa`

ReKHCoM is a PC port of Kingdom Hearts: Chain of Memories for the Game Boy Advance, built on Pheenoh's matching decompilation of the game. The decompiled C code is compiled into a 32-bit Windows program with its own renderer, sound mixer and launcher, while the game's graphics, sound and text are read from the player's own cartridge dump at start-up.

Fields and battles widen to fill 16:9 and ultrawide screens up to 32:9 without stretching, and menus that stay at their original size are framed with art extended from their own edges. The game runs at the cartridge's own speed, with optional audio smoothing, full-screen movies and an HD font for dialogue, subtitles and menus. Each new game can be the original exactly as on the cartridge or Re:Chain of Memories, which brings in ideas from the PlayStation 2 remake: Beginner, Standard and Proud difficulty, faster dialogue and a one-button dodge and card stock.

The European, US and Japanese cartridges all work, in every language they contain, and each keeps its own save. The launcher installs and checks the dump, imports Game Boy Advance saves and backs them up. A browser version is in alpha. The download includes the project's launcher artwork but no ROM or game data.

## How to set it up

1. Download the Windows zip and extract it into a folder you can write to.
2. Run `ReKHCoM.exe` and choose **Install ROM...**, or drag your dump onto the window. It is checked and copied into the `roms` folder.
3. Pick the version, language, graphics, sound and controls in the launcher, then press **Play**.
4. When starting a new game, choose Original or Re:Chain of Memories. START + SELECT changes the settings later.
