I've asked all this before and got no response at all, including when I emailed the dev directly requesting help. A step-by-step guide would be nice, as for a start I don't know what cheat codes can be used. All the ones I've tried so far have frozen up the emulator whenever I've tried to input them.

I see Fpse has the ability to use cheat codes.

However I can't figure out what I need to do with them - where do I get the codes from? When do I enter them?

Is it game shark/action repla codes or something different ?
