I've been exploring the ways to get a multiregion MegaCD on the go. It seems the only ways are Datel CD-X carts or the MultiBIOS mod.
But then I realised that I'm only gonna be getting Japanese MD/MCD games anyway, and the MD will permanently be set to 60Hz/Jpn. It just seems that as and when NTSC-J MD/MCDs show up on Ebay, they go for a fair amount; whereas PAL ones go for very cheap. So, basically I'll stop rambling and ask my actual questions -
* I've heared that some Model 1 MCD units have socketed BIOS? Can anyone confirm this (makes things easier).....?
* What eprom would I need to use to just put the Japanese BIOS on (131,072bytes)? So I can transform a PAL MCD completely into a Japanese one.
*What eprom would I need to use so I can have 4 switchable partitions and do the multiBIOS mod myself?
Cool. Thanks very much[/url]

I put a multibios in my Sega CD, and it works great. It was a model 2, though, so I can't comment on the model 1. For 128k, you'd need a 64k * 16 EPROM, which is a 27210. For 4 BIOSes, you'd need 256k * 16, which is a 27240. Personally I only installed the Japanese and US BIOSes, since I didn't see any UK-only Sega CD games worth playing.
