Hi :)

The next idea would be to put images of the different Rom Boards of the games, to
see where they find the good locations of the EPROM & MASK-ROM for possible
conversions & update revisions :saint: .


With bonus a small image of the Security Chip related to the game if it is existing 8)

Sega Model 2 : Virtua Fighter 2.1

MODEL 2 A-CRX CPU BD / MODEL 2 A-CRX ROM BD




Sega Model 2 : Dead or Alive

MODEL 2 A-CRX CPU BD / MODEL 2 A-CRX ROM BD



Security Chip :




Sega Model 2 : Virtua Stiker

MODEL 2 B-CRX CPU BD / MODEL 2 B-CRX ROM BD

in the mame driver it mentions a scsi interface.
these boards dont access all those roms as a solid-state scsi-drive do they??
*that* would open a whole shitload of interesting possibilitys!!!!
 
anyone have a copy of photos, which is gone now ?
I'm interested to see Dead or Alive security board.
 
looking for the jumper settings for Dead or Alive and Zero Gunner, both on Model 2 B-CRX.
 
Do you need eprom locations for DOA?
let me know, they are in my manual
 
thanks a lot for the snaps. Those confirm my findings. So my DIP settings look ok. I took the eprom locations from the MAME source code. So that should be fine on my end.
