hello,
I don't have that game so I'll only ask question to understand and fix the problem.
Which loader name, which version, which game region ?
How many cheats did you enable ? only one or multiple cheats ?
which one ?
Some cheat code are conflicting with each others
Some cheat code requires that you edit a value and set your own numbers in hexadecimal
some cheat code works only with specific game region
some cheat code works only with specific Cheat Hooktype (VBI, KPAD Read, GXDraw, etc.)
To know which specific setting you need to set, you have to read the comments of that cheat.
Unfortunately, the loaders are not displaying comments.
Either you open the cheat .txt on your computer (or phone) and look if there are any instruction in it to either set a value manually, or use a specific hooktype.
By checking the cheat text for Harvest Moon Animal Parade [RBIEE9] (USA version), it doesn't appear to be any user editable field, nor specific hooktype instruction.
it's leaving either conflicting cheats enabled at the same time, or wrong cheat region (PAL instead of USA, etc.), or game ISO corrupted (check your ISO if you are not playing from disc), or another USB loader's patch incompatible with cheats (480p fix, language patch, aspect ratio, etc.)
