So I had an R4 (it could also be an action replay) and turned on Max S. Exp code, then saved the game. After that, it crashed everytime I opened the S. Exp screen, the S. Exp wasn't working, and even after I turned off the game and same thing with the cheat. I was quite sad, because other S. Exp cheats didn't work either. So, I rebuilt the cheat to fix this problem. Messed up code: Warning: Spoilers inside! ::Max S. EXP Code: C0000000 00000027 02135AC8 C350C350 02135AD4 C350C350 02135AD8 C350C350 02135AE0 C350C350 DC000000 00000164 D2000000 00000000 Fixed code: Warning: Spoilers inside! ::Max S. Exp Fix Code :::Use if you have used the S. Exp cheat and now it crashes when going into the S. Exp screen Code: C0000000 00000027 02135AC8 0001869F 12135ACC 0001869F 12135AD0 0001869F 02135AD4 0001869F 02135AD8 0001869F 12135ADC 0001869F 02135AE0 0001869F 12135AE4 0001869F DC000000 00000164 D2000000 00000000 Messed up code with why it didnt work: Code: 02135AC8 C350C350 C350 in hex is 50000 but the whole byte is being used, resulting in 3276850000. The game only uses 99999, so obviously it would work. 0001869F converted is 99999, which is the max amount.
