Model2新進展！

"Stalling till infinity …"

Starting to work on Sega Model 2 HW, which definitely deserved some love
for the importance that this HW went in mid-90s. With some aid from from
Haze, providing snippets of information from ElSemi’s code here goes
some WIP snaps:

Of course it’s still a long way to go. And anyway, main problem lies in
FIFO comms: BOTH CPUs stalls at arbitrary points in several games (Virtua
Fighter 2, Fighting Vipers and so on), trying to read an empty FIFO
instead of alternating between reads and writes.
