hm i had the location of the byte 0xEE written down at some point.. i'll see if i can find it.

you could probably get by with another unique byte, for example byte 0x43 will always exist at 0x2005 in an EE bin as part of the DE CORP copyright

that's probably unique enough unless you're putting near every xdf in existance in there; then you may run into collisions.

this doesn't deal with EEB since i think the copyright is in the same spot; but i dont think a good EEB xdf exists anyway, and that mask is pretty rare
