|| MAME 0.120u1
|| R. Belmont, f205v
It's a modified PC running a modified version of mame32. The HD has been converted into a CHD.
Bios has finally been dumped, as well as CPUID.
update 20080508: Update from ANY:
Each HD is bond to a specific motherboard (CPU serial); when an HD crashes the manufacturer can not simply replace the HD, they want to have back the full harness.
Each HD is also somewhat linked to its own datas (model, serial number???); if a clone HD is used on the machine after a while it hangs in test mode.
