Yeah, but I doubt the Saturn could have run much backups, seeing how it couldn't read a simple music CD I burned...
Oh yeah I remember the Dreamcast, I had a DC-X, 40-something original games (including Ikaruga, KoF 2000 and 2001 and the Sakura Taisen Collection limited box), then I got some autoboot isos, and I burned a Utopia 1.3 for some non-autobootable backups I had. Man that was my favourite console, I liked it better than my PS2. Someday I'll fire it up back and play my old games again. I still have my 7 or 8 VMUs and my Nexus Memory Card... \o/
An old friend of mine had found a swap trick, and he was among the first people to play GGX on Dreamcast in France at the time.
Anyways I might have the swap trick videos on an older hard drive somewhere over the rainbow -nah just in my old laptop. Basically you need to trick the weight lock open to let the lid up, start your regular game, remove it when the SEGA logo is displayed, then put your desired game, then swap it for the regular again, then another swap, and it's all based on listening to the noise the CD player makes while spinning, it's precise and demanding, but apparently it works... Maybe you can find it by lurking on YouTube...
