Hey guys. I have cheat engine and used it to find different cheats for SMBX, and here are some (tested for smbx 1.3 ONLY): ----- Powerup that mario currently has: 003130A6 (Byte): 1 is small mario 2 is big mario 3 is fire mario 4 is tanooki mario 5 is cat mario 6 is hammer mario 7 is ice mario 8+ is invisible mario EDIT: After restarting I found that the address for Powerup can also be 00CE30EE How many lives are left: 00B2C5AC (Float): Set the value to how many lives Mario has. ----- If anybody wants to submit codes just post and I will add them! EDIT: I might make a program that will attach to SMBX and automatically use these codes. Thanks!
