Irem M92-A boards compatability

From this list I see different versions, earlier games like Gunforce M92-A and later games like Gunforce M92-G ( and other versions in between)

Is the main board interchangable from 91-94 games. Will GF2 work on a GF mother board. There are some jumpers, guess they may have to be switched ?
