Super BetsuBetsu Turbo (Video/Audio splitter + keyremap/autofire)

[buffi]

This is definitely just in the thinking-out-loud phase so far, but have been thinking about doing a version of BetsuBetsu which in addition to audio + video splitting for streaming, also does button remapping + autofire.

Current thinking is support something like:
- Video out (MD2 RGB)
- Audio out (Audio jack)
- Video gain triple pot
- Voltmeter
- P1 and P2 button mapping for four buttons
- Per button autofire support

For autofire allow:
- Tied to CSYNC (or not)
- Multiple inputs mapped to same button, allowing both continous and auto for same button through different inputs
- (Maybe, but probably not) Allow mapping P2 input-buttons to P1 controls. Could be used for extra auto-buttons.
- On-board LED's showing current mapping. Pulsing in autofire frequency if autofire.
- Autofire programming done using two onboard buttons + cabinet buttons

WIP board layout below.
Will not be as DIY solder friendly as current board, since it uses some 0402 components and so on to make routing less bullshit. Will need to use assembly services to put together.
Haven't even started on firmware.

If I actually end up finishing this, it is not likely to be done this year.

Definitely like the addition of the remap/autofire. I am sure some people would rather see VGA for video out.

Look forward to watch the progress.
