I've known about ROMS and Emulators for about two years now. Here are some of my favorite games:
SNES
Chrono Trigger
Breath of Fire
Yoshi's Island
Macross: Shattered Valkyrie
Tenchi Muyo! RPG
Super Metroid
Dragonball Z: Hyper Dimension
Mega Man & Bass
TMNT 4: Turtles In Time
Super Mario All-Stars
X-Men: Mutant Apocalypse
Genesis
Streets of Rage 2
Spider-Man
Sonic 3 w/ Knuckles
any of the Shinobi games
GBA
Mega Man Battle Network 2
Sonic Advance
Super Mario World: Super Mario Advance 2
Spider-Man: The Movie
Castlevania: Harmony of Dissonance
As for reliable sites to download ROMS from, you'll have to search around. Whenever I find a site that has a ROM I'm looking for, it's closed whenever I go back. Go figure.
