Posted yesterday on the Hacking forum, the Sega CD BIOS has been disassembled. From this point it would be fairly easy to create a bios that has NO country select, which could be added to a modded Sega CD. You can download it here.

Hey all you people. Hey all you people. Hey all you people why don't you listen to meeeee? I just made a disasm, but no ordinary disasm, a disasm that needs your editing. If anybody can help to clean this up, add comments, anything like that, please let me know, or not, I don't really care =P

Hey segaloco, can I ask you question?

I have dumped my mobile phone firmware (LG KP501 cookie), and managed to change the IMEI number and found the network unlock codes.

I'm also trying to see what hacks could I make to my satellite tv receiver firmware (echostar 8100). So far I found the number of the node it dials when buying pay per view movies and the username and password it uses to connect. But I wonder how far I could go with a disasm.

So the question is, how do you disasm bioses/programs that are not for standard processors? I just want to know where could I start looking.

IDA Pro. If your CPU isn't supported, look for an extension. Sorry this post isn't long, IPB3 is a bitch on PSP.

Your post fails it, but I assume I know what you are talking about: the MultiBIOS. It is just the three region bios mashed together with Columns into a 512kb file for EPROM writing. Uses switches for region switching, so it's not really hacked, other than the custom logo.
