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:

Fighting Vipers

Last Bronx

Sega Rally (added “Eye Mode”, used by car selection)

Virtua Cop

Virtua Cop 2 (no textures, if it wasn’t clear)

Virtua Striker

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.
