Banpresto medal games with Seibu customs

Confirmed games (but there are probably several more):
Mario Undoukai
Terebi Denwa Doraemon

The following is from Mario Undoukai PCB pics:

BS9001-2 main PCB + BS9001-A ROM PCB
Main components:
- MC68000P10 main CPU
- 16.000 MHz XTAL (near M68000)
- 8-dip bank
- SEI0160 Seibu custom
- SEI0181 Seibu custom
- SEI0200 Seibu custom
- SEI0211 Seibu custom
- SEI0220BP Seibu custom
- 14.31818 MHz XTAL (near Seibu video customs)
- OKI M6295
The audio section also has unpopulated spaces marked for a Z80, a YM2203 and a SEI01008


TODO:
- printer or hopper emulation
- the GFX emulation was adapted from other drivers using the Seibu customs, it might need more adjustments
- verify Oki banking (needs someone who understands Japanese to check if speech makes sense when it gets called)
- lamps
- 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.
  tvdenwad will go back to the call assistant screen shortly after starting (believed to be because of missing printer or hopper emulation)
