Pre-FCC system in a grey case. I have one of these, and there's one on "that auction site". Besides the color difference has the bios been dumped yet?
Not that I know of. I wrote a program that dumps the bios to memory card, you need some way of transfering files from memory card but it means you don't have to risk plugging in an action replay. I can dig out the cd and upload it if you want. It would suprise me if it was much different from the release one. A pre-release japanese one would be much more interesting. A DTL-H500 bios dump is the holy grail.
Assembler mentioned that there's one of these on the other auction site. What site is that and is it still there? I wouldn't mind grabbing one if it has the s-video out built in!
