Kingdom Hearts Birth By Sleep

[KingdomHearts4L]

Okay so I am really new to ppsspp but, I do have other emulators. The ONLY reason I use emulators is to complete the kingdom hearts series in consecutive order. The psp kh is the 1st one (storyline wise). Anyway I downloaded version 1.2.2 (ppsspp) and everything was working perfectly, I was playing, it was no lag, cutscenes were perfect all of that. Until one day I was having trouble with a boss so I decided to enter a cheat and I went into the memstick folder cheats and pasted my cheats for the game on the notepad thing. only one cheat worked at the time which was infinite money so I looked for other cheats because I thought the others weren't compatible or w.e. I do believe I found some that work BUT whn I entered the cheats in notepad and tried to load my save game not save state (I did save game with cheats enabled and a cheat running) it said ppsspp not working and windows is looking for resolution blah blah close program and I even tried to load it with cheats disabled still didn't work and I tried loading a new game with cheats disabled and it worked for a little while and then the ppsspp not working thing came up again HELP PLZ I would like for cheats to work and game to run anyone have any ideas I'm using windows 8 btw and its a USA iso version of kingdom hearts birth by sleep THANKS!!!
