I want to use the Sony HDD to load REO and SocomII faster. The problem is that I have a messiah 2 pro chip installed on the system. So I am planning to replace the chip with DMS3v2. I have look at both installation guide for version 7 of the PS2 and it seems that both uses the same PS2 motherboard pins, the question is would there be any problem if I just cut off the Messiah 2 pro and just use the same wire? I would just need to solder the wires to the DMS3 chip and leave the wires to the motherboard alone.
