Yes I know there's emulators but I'm wanting to build a emulator pc but boot different game system OS's from a bootable flashdrive or windows. Pretty much I'm wondering if I can get a pc running that can run games from NES to PS2 but is there a way to extract the OS from the system or make a copy of it? Sure I don't mind running things from roms to actual discs. Or is there a "Homebrew channel" kind of thing where I can download and launch roms from it or have a emulator read a disc and run it in possibly multiple formats? Also I don't really know the best place to post this so sorry if this is the wrong place. Thanks
