Hello, the nes emulator i had for my dreamcast allowed me to save whenever in the middle of the game but the one for the ps2 doesn't allow you to do that? or i just can't figure out how to do it...
which emulator do ou have? their should be a in game menu that you can access by pulling the analog stick right and pressing select or start.Then you can chose something like "save state" and that will save to your memory card.Remember always read the readme files that come with the emulators they will say the features of the program.
