Currenlty running PIN2DMD firmware 2.50 and no issues.
When I install the PinUp Player 1.2 I need to install dmdext 1.6 prior to the installation (replacing the dmddevice.dll from Lucky). The dmddevice.dll and ini from dmdext are slightly modified via the PinUP 1.2 player during installation to ensure rom interaction for video display. The issue I have with this version of the dmddevice.dll is that some of the color roms do not display the colors correctly (know issue) but I also experience sound issues with DataEast roms like T2, LW3 and Batman. The only solution to solve this currenly is to revert back to the dmddevice.dll from Lucky that relates to the 2.50 firmware.
