changing the DMD ROM in GnR issue
« on: June 20, 2011, 02:57:17 PM »
Just picked up some new English ROMs from John Wart Jr. One for the CPU and the other for the DMD. The new CPU rom is ok but the new DMD rom shows nothing on the DMD. I put the old DMD rom back in and its ok - is there something I'm missing here? !@#

Im sure I put it in the right way.

I noticed some dipswitches on the DMD board - what are they for?
