new machines marked as NOT WORKING
--- Goldart (Spain) [Morten Kirkegaard, Ryan Holtz, Clawgrip, David Haywood, Roberto Fresca, Peter Wilhelmsen] video hardware is bitmap based, but seems to have some control registers so palette etc. is set outside of the actual writes, might also disagree with how the ds5002fp core does memory addressing slightly as some bits seem to be fetched from the wrong places. ds5002fp dump we have is good enough to run the attract mode on PCB, only 2 suspicious bytes.
