i have 3 nintendo vs boards and i have 3 different versions or so it says on the top of the board. one is mds-03-cpu, mds-04-cpu and finally mds-05-cpu. is there a difference between them? they look the same except for mds 3 which has a different chip at 6e and 1e which is smaller? im just curious as i have a gumshoe that im trying to get to work but it seems to freeze alot in the current 04 board. and they do have the memory boost mod already on them.
