Bios options - Retail region free?

[segadreamcaster]

Hi all,

As much as I like the region free bios thats available (with dev kiy intro), I would like to have the option to flash to a region free standard retail bios. I know this is possible, but does anybody have this bios and a method of flashing it?

Thanks in advance

Cheers

Ok, solved my own question here...I managed to hex edit the bios files on dreamshell and then burn it using bootdreams and alcohol 120%

The question now is (which I just asked at assember games as well actually) is what is the difference between the retail bios options? Are there any advantages or disadvantages between them?

Cheers

bios is not so easy to change, it is can block GD-ROM.
In any case is no difference.
