    Hey guys,

    Got myself a Pal Mega CD II unit.
    Just wanting to try out the different BIOS using my everdrive cart.

    i just get a blank screen when I use Russell-region-free-cd-bios.bin file.

    i have tried a few different ones but still get a blank screen once run.
    Any ideas on getting this going?

    Thanks for that but I think the link is dead.
    I found a bios on Krikzz web page so I am good to go now.

    If the bios file is meant to be burnt on a EPROM (I think that's the case with the Russel PAL-MEGA-CD bios) it won't work on Everdrive because it will be byteswapped. :thumbsup:

    KRIKzz, I have Sega Multi-Mega PAL-Asia. Japan region games working on it. With your Russell-region-free-cd-bios.bin most of games works fine, but the Silpheed doesn't. Can I load on MDEverdrive PAL BIOS? And where can I find it?

    It for unknown for me reason plays only Japan region games. So I'm patching ISO region to Japan before burning CD-R. But yesterday I've bought Silpheed PAL(UK standart), and it didn't play when I'm loading free-cd-bios. After I've try my Silpheed.iso PAL in which I've changed region to Japan, and without free-cd-bios - it wirks fine, with free-cd-bios it doesn't work.

    So can I load PAL bios on EverdriveMD and run the game?
