As the title asks, can I flash a TNT2 Pro BIOS on a TNT2 M64 card?
I have a few of these M64s laying around and wondered if the BIOS can be crossflashed to Pro, similar to how the FX5200 can be flashed to 5500.

Pretty certain the architectural differences between the M64 (NV6) and the TNT2/Pro/Ultra (NV5) would scupper the chances of this working properly or possibly at all?
I’ve got no evidence for this though so feel free to try it and prove me wrong!
As far as Wikipedia tells it, it seems the same NV5 chip was also used for the M64, with the exception that instead of 128bit it's on a 64bit bus.

Not according to the Wikipedia article I’m looking at…
well, crosflashing bios would not solve enything but you need to resolder resitors in order to change ID of the card.
maybe additional ram chips on board with unpopulated ram would do something like incrasing memory path from 64bit to full
there is nice bit of info here

i wish i had access to my soldering equipment right now as i am interested in making use of those bunch of useless tnt2 m64s
i had even ordered fast sd ram (~200 mhz) in atempt to voltmod m64 and overclock it to the max
