I just downloaded a glide2x.dll whatever thing. I tried out the emulator, it said a message about it not being able to run properly, and then it ran. The message only popped up once, and now it runs without the message popping up. Perfectly.
So, I guess I'm all set. Thanks anyway.
EDIT-- Wait, the program shuts itself down all of the sudden all the time.
You know what, fuck this. I'll just play the crappy ZSNES emulator that I have, which makes the screen jitter sometimes and makes half the sprites not appear some of the time.
