Installation

To run the game on a NDS, you need either FlashME, WifiME or a PassME and some sort of GBA flashcard or the GBA Movie Player with chism firmware update.

If you own a flash card with DLDI support you can change the opening book (the one compiled into the ds-file is very small) to a bigger one by putting it onto your cf or sd card (of course you have to patch DSChess for your device first). It must be called book_small.bin. The book has to be created with PolyGlot.

DSChess saves the game after every play, so you can resume your last played game. This works only if your card supports DLDI with write support.

You can test DSChess without a DS with emulators e.g. DeSmuMe or no$gba.

 DSChess is a homebrew chess game for the Nintendo DS. It builds upon a very strong open source chess engine called Fruit 2.1 by Fabien Letouzey (free again: www.fruitchess.com). The engine was changed to meet the requirements of the Nintendo DS. It is the strongest playing chess game on the Nintendo DS as two representative matches against Chessmaster and Schach has shown.
