If you can save normally nothing will happen later on unless you get some kind of memory corruption which while rare, is always a possibility especially if you would never restart the emulation and reload the game normally. Game wouldn't really recognize a corruption from cheating, also usually anti-cheat systems are actually there to avoid saving corrupted data, so in a way that's a good thing.

I'm at my third playthrough with only few records missing still and added uniforms on like 2nd chapter during my first playthrough, so yeah I wouldn't worry about editing inventory as long as you do it the right way ~ on save screen;]. Also if you're playing translated game, it's all on a single umd image.
