Just wanted to tell you that if you want pure roms,not that many pop-up crap,go to www.edgeemu.com like Joe said,www.vimm.net won´t probably do bad either.
GO TO www.zsnes.com for Super Nintendo emulator,go to files section and download the new piece of emulating.
If you want nintendo 8-bit roms,go to the same adresses,after downloading those emulators,create a directory for them,and place those roms there too.
Zsnes is the best emulator for Snes,easy to use and works very well.
Nesticle is quite good for basic nes(nintendo)
or you may use Jnes.
You need DirectX8 to play with Zsnes.
Yeah,that´s enough about all the mouthing off…
I personally had success with RockNes, its simple and works really well too
Are you on crack? None of those sites had ROMS. It is so **** hard to find a friggin place that has ROMS.
www.emuchina.net
www.emulando.com.br
www.emumaniacos.com.br
To decryptate the cps2 roms (found on other sites) use:
www.cps2shock.com
geeks.. 
http://www.theroms.com/ isn’t to bad, thanks Skarbromantis. Has anyone used any good N64 emulators?
