I was talking about pokemon white but it isn't working for any Pokemon game

It might be the rom

Whenever I try to hold a button for a cheat e.g. hold l to get max money, doesn't work

Oh also the rom wasn't deleting my save files before

The save was only getting erased recently, it might be due to a combination of cheats or I remember I tried to change my time but I just set it back to my phones, also I got the rom from EmulatorGames.net, is their something wrong with that sites roms?

I can't do trial and error because I have to save the game and restart to disable cheats but whenever I do that my save file gets erased, also im using the saves on the menu not savestates because I read that I wasn't supposed to

What cheats could be corrupting it?

I'm playing Pokemon white and whenever I reset it says "your file will be erased due to corruption or damage, how do I fix this?
