Welp... I had SMBX 1.3 and it worked fairly well. I just got SMBX 1.4.3 and no cheats will work. This may be my stupidity, my PC, or the game... Still, please try to help me with this one... :P BTW, just... Literally none work. I may not know how to access them, but I don't know what to do about this.
