Okay this isn't actually for me but a mate of mine

I have a DS emulator, but I don't play the only game I have for it, (diamond) because its SO SLOW.
Any help on why that might be?

That's what he wrote, now I don't have the problem myself cause I got it fixed but my memory sucks so I can't remember the info/details of how to fix it and know the forum I found the information on and will try and track it down, but it's a big pretty big forum and I don't know how long it'll take so I thought you guys might be able to help quicker.
