Most 4 MBit and 8 Mbits rom run perfect from CD to SF7.
However, some got error message "Disk format error" when it was loading on the half way throught.
For example , 32Mbit game, 4 disks - Finish loading disk A 100% and loading disk B up to 30% or 50 % ...error message appear.
Do you have same problem ? Any idea how to fix it?
