It seems like YSM3 can't handle cheat codes created using DB and D8 (no effect) Type 0xDB 8-Bit Load DB000000 XXXXXXXX Loads the byte at [XXXXXXXX+offset] and stores it in the'Dx data register'. This is a bugged code type. Check 'AR Hack #0' for the fix. Type 0xD8 8-Bit Incrementive Write D8000000 XXXXXXXX Writes the 'Dx data' byte to [XXXXXXXX+offset], and increments the offset by 1. example: Plants vs Zombies Always begin at Final Wave 922a17c0 00000001 DB000000 022a17a4 D8000000 022a17c0 D2000000 00000000 922a1860 00000001 DB000000 022a1844 D8000000 022a1860 D2000000 00000000 Above Code works 100% in M3Sakua and AKAIO Wonder if it's just a YSM3 bug or YSMENU bug itself????
