The 3rd Birthday

[Ordinario]

I'm having problems with the game. I'm not sure if it's because of the cheats or not but the problem is there are times that the background freezes along with the enemies except for Aya and she will run continually even I'm not holding the analog pad. There are also some time whenever she falls on the floor and she won't get up anymore. How can I fix this? Anybody knows how? Please help me. I tried to deactivate all the cheats yet this glitch(?) keeps on happening.
