Fire Red cheat codes keep freezing my game

Trying a few codes on an old Action Replay with my Fire Red cart, mostly rare candy and wild encounter ones. Half of them freeze on the title screen. Do the codes need a master code first, or does the order you enter them matter?

what emulator? some are a lot fussier with cheats than others. if a code works for everyone else and freezes yours, try it on a different emulator before writing it off. add codes one at a time as well, so when it freezes you know which one did it.

Most freezes come from a few things: - the code is for the wrong version of the ROM. Fire Red 1.0 and 1.1 need different codes, so check which one you have - codes for a different cheat format. GameShark and CodeBreaker codes aren't interchangeable, and a lot of emulators want you to pick the right type when adding them - missing master code, if your emulator needs one - too many codes on at once. Walk through walls in particular causes all sorts of problems Also save normally before turning any code on, and switch it off before saving again. A code left running when you save is how people end up with a corrupted file.
