- controls / dips need to be completed and better arranged
- currently stuck at the call assistant screen due to vendor test failing (printer / hopper?), but can enter test mode.
To test the games, it's possible to get the attract mode running by enabling the hack in the memory map at 0xe0004-0xe0005.
tvphoned will go back to the call assistant screen shortly after starting (both believed to be because of missing printer or hopper emulation)
