i listened about compatibility between hd and la riders model 3 step 2 and daytona 2 board step 2.1
so i bought a complete HD for my daytona and tryed to exchange the hd game rom for the DAYTONA 2 , and nothing is working
i would like to ask to people here if i was wrong about compatibility or something wrong to my daytona 2 game rom i tryed to change to the step 2 cpu and video board
Right, just swap the ROM boards and remove the DUSA2 small security PCB. I have done the same exact switch and it works fine. If it doesn't there is something wrong with the ROM board that is not working
