Changing to Japanese mode on MVS

After reading some posts about how playing games in US mode, disables some nice features I was wondering how to change an MVS 4 slot to work in japanese?

I bought all my MVS boards (2 4 slots and 2 1 slots) from arcade infinity. I have 1 4 slot in japanese and 1 4 slot in US mode. Jack Tao changed 1 chip on one of the 4 slots to make it work in US mode. I was wondering where I can get a chip to make it work in japanese and if there are any faqs/diagrams showing what chip to switch.

Thanks in advance, any help would be greatly appreciated.

You need the UNIVERSE BIOS, see web page in my sig.

Raz

Yep, you need Raz's unibios, they're definately HIGHLY recommended around here. Only takes about 30 seconds TOPS to switch it out too, couldn't get any easier.
