In Emulators / NES ROMs

I have tryed Rocknes but all the NES Games run to damn SLOW!!! it must be my PC! anyways is there any Nes Emu's that run on 80%-100% on crappy computers?

Try not to run them in full screen.

a little part of the screen is the game and the rest is all black.

Click that

I dunno, you might wanna try FCEU

To my knowledge, JNES is pretty low impact as far as emulators go. Try that out, it doesn't require a very POWerful computer.

How crappy is your computer?

Even on my old PC I could play NES and SNES emus with no problems.

Whoa...nes going slow on a comp never heard of that. But on my old slow comp i used jnes and had no problems. Try that out.
