PEC question

Ok so i installed PEC, i select the cheats i want to use, i hit send cheats to plugin, but when i start the game, and enter a battle the emu lags horribly, and not to mention when i close the emu the music keeps playing, lol.

Which emulator are you using? If you here the music playing in the background the emulator is not closed. Try closing it out through the task manager.
