I have an SVA and an Inty II w/ECS. I also have an LTO Flash cart and the MTE201 diagnostic ROM. I have seen, though, that the MTE201 seems to work differently between the SVA and the Inty II. I'm sure this must be because of the consolidated chips on the Inty II. I recapped an Inty II recently and saw the differences firsthand.
I've looked online but can't find a separate diagnostic ROM for the Inty II. Is there such a thing? If so, can someone point me in the right direction? It'd be a valuable resource for us Inty II owners that can make use of it.
