Not much new to report today. I updated the driver to support a new romset, PP0188 - Standard Draw Poker. A screenshot of it is pictured here with the paytable option on. This rom also has an AutoHold feature, but was disabled. It has been suggested that depending on a casino's location and policies, that they will sometimes enable or disable this feature.
I had to apply the same code hacks as the PP0516 driver to make it work. But it does work as far as the others go.
I just updated my driver against the MAME .120 source and submitted it again. Hopefully the next revision will have some of the changes and bug fixes I made to the 8051 core.
