What cheat file does M3 Sakura use?
(Top) A: It uses the same cheat file as the M3 Real (cheat.db). Download, extract and copy the file to the SYSTEM folder (overwrite the old one if present) and you’re all set! Access the cheat menu by sliding NDS ROMs to the left, or by highlighting the NDS ROM and pressing Y. You can always get the latest cheat compilation file from the GBATemp Cheat Database, maintained by Narin. Note that cheats will not work if Download Play is set to “Enable” (thanks for the tip AXYPB). Some cheats do not work, even with Download Play disabled.
