yep, its a very simple banking. at PIO offset 0x7fffff games writes some value. so at DMA transfer offset calculation you must substract this value * 0x02000000 from dma_offset.
but probably you will not have time to add/change ~3 lines of code to implement this, because I see you are such too busy, so even cant just add 2 Naomi dumps made by rtw about 4 month ago...
add: I even not saying about IRQ handling separation request I've made afair several month ago, having which I can implement (basic) Naomi2 stuff in MAME... but the truth - no one gives shit about this stuff, but not too busy to (primitive) troll about "some stuff Demul guys discovered but hiding" lol
