Emulation of SNES, PSX, N64 games are quite new (circa 1998 or above, in the case of the N64 emulators, which is January of this year) and the technology is taken mostly from the video game carts and cds in the advancing world of VIDEOGAMES
"So what?" you say?
Emulation COULD be the next wave of video gaming! I hope so, anyway -- I'd rather spend my money on other things than $80 a pop for a N64 game or something! On this site, demos are coming soon, as well as various rare Japanese ROMs (Bahamut Lagoon, FF2j-FF5j, Dragon Quest, Dragon Ball Z) and various Squaresoft carts (FF1-6).
