Gakken Compact Vision TV Boy (TVボーイ)
|
||||
|
||||
Hardware notes:
|
||||
- HD6801V0P or MC6801U4 @ 3.57MHz
|
||||
- MC6847, MC1372
|
||||
- 2KB RAM (HM6116)
|
||||
- 1-bit sound with volume filter
|
||||
- cartridge slot
|
||||
|
||||
There is no CPU inside the console. The MCU is on the cartridge, the console
|
||||
itself has the video hardware and buttons.
|
||||
|
||||
TODO:
|
||||
- add softwarelist
|
||||
- add volume decay (frogger uses it according to a video)
|
||||
- some games don't work yet, assuming it's due to MCU emulation
