Changes

The first is the virtual FPS. If this is running at 60/60 then the emulator is running at full speed. The second is the real internal FPS, which is whatever the game actually ran aton real hardware. Most consoles use the following internal FPS based on region:

If you are experiencing a slowdown, it may be that the emulation is too intense for your system. When this happens, both the video and the sound experience slowdown. To counter act counteract this, you can enable speed hacks, use a less intensive emulator/settings or get a new CPU. However, the slowdown may be part of the original game, and will be emulated. As such there is nothing that can be really done, short of reprogramming the game itself or emulating an overclock. When this slowdown occurs, the video will slowdown slow down but the audio will often continue at full speed.

A way to counter real internal slowdown is to overclock the CPU of the emulated system. This , of course , requires a faster CPU to run the emulator of course. It may result in a smoother frame rate, or unintended effects such as speeding up the entire game. It is very game and system dependent. Emulators that support this:
