Get the ROM Running the Easy Way
Longtime GBAtemp member iNFiNiTY has released an Action Replay code made for the Grand Theft Auto: Chinatown Wars Nintendo DS ROM that will enable it to run on any flashcart without any problems. This method does not require any ARM7 patching for most popular Slot-1 flashcarts (CycloDS, Acekard 2, etc.).
YGXE DEE4AA12 is the Game ID and 020FCB3C 22329203 is the Action Replay code you need to add to the GTA: CW ROM so it will function normally on your flashcart.
Remember, all flashcarts require different methods of inserting Action replay codes.
