Not that I know of.

But you can play demos/games of some of the games on this site.

Uum.. this isn't really the place for these types of questions, but since it's already here..

You could try TPPC, it's better than PokemonCrater ever was in my opnion. :/

That's the Game Development Forum. They don't use ROMs.
