Bad ROMs on NAOMI carts
« on: October 23, 2020, 02:10:29 PM »
I found bad ROMs on some recently acquired NAOMI carts.

Are they worth repairing or are they pretty much trash?

Thanks

depends on the board, but most likely its bad mux chips, not roms.

Yeah, they were part of a package deal and presumed working, but I had no way to test when I picked them up. ¯\_(ツ)_/¯

So here's what I get from running a ROM BORAD [sic] test on Marvel vs. Capcom 2, and I get a similar result on the Dead or Alive 2 cart. Any way to tell from this how much work it would be to rescue them?
