oh man. do you guys even read?
x3 bios's big thing is being able to change all settings directly on the chip. this hacked bios doesn't support that. so you have a bios with some default settings which you can't change in any way, and a way, way, way old build of it (one of the first, buggy ones) to boot. which makes this utterly, completely USELESS.
and it's 1 MB too so it won't even fit on most of the basic chips (aladdin etc).
