Internally, the super board maps the game data rom in all the external addresses the non-superboard had not used. After tracing the schematics, I determined the addresses are $1000, $3000, $5000, $7000, $9000, $B000, $D000 and $F000. So even though the game rom is stored on a 64k chip, only every other page actually can contain data. This essentually adds 32K of information to the superboard romsets.

With these changes added to the driver, I can now support the rather large list of superboard roms too. The slot pictured above is the Triple Triple Diamond Video Slot (XS000006) romset for the superboard. The slot driver uncovered some additional issues with video processing that I had not encountered before. Once I figured out the issue, the slot reels lined up nicely and the gameplay was correct.
Another romset now supported is the Deuces Wild Video Poker (XP000019). It is similar to many of the video poker romsets but has a few different graphics and gameplay with 2's being wild.

At this point I am finding some small issues with the coin hopper timing when the machine tries to payout coins. I sometimes get a hopper empty or coin-out timeout message. It appears I will need to do something similar as the ABC optics for the coin-in mechanism, but not as complex. Some initial code appears to work on the non-superboard romsets.

YES, you are GOD.
Been waiting for these to be emulated
for what seems a lifetime.
Keep up the great work.
P.S
I Think these deserve to be on a standalone emulator, but thats just my opinion.
