Atmosphere enables all cheats it finds in the cheat file by default. That is probably why you experience that your game doesn't start just by having the cheat file on your SD card. You can disable that by changing the line '; dmnt_cheats_enabled_by_default = u8!0x1' to 'dmnt_cheats_enabled_by_default = u8!0x0' in systems_settings.ini and reboot. If you haven't changed anything in the ini file before you can find it in \atmosphere\config_template on your SD card. Copy the file to \atmosphere\configHaving one of the weirdest issues, Was playing Xenoblade DE, and wanted to shorten the grind I was doing a bit by getting a xp modifier cheat, so I downloaded the tesla overlays for edizon, then used the All In one updater homebrew to download the cheats files, however after I had done that Xenoblade DE refuses to run, it will crash with the software closed because an error occurred error if I try and run it, thought it was the tesla stuff so removed those and rebooted, no dice, thought perhaps me going into edizon manually when the game was running previously perhaps corrupted the game so reinstalled it, no dice, however I noticed if I used the all in one app to delete the cheats file the game suddenly will run again, no idea why just the cheats file itself is breaking things anyone know?
Now you can enable the cheats you want ingame from the Tesla menu.
