The hardware for many pre-cps1 capcom games were reverse engineered by Jose Tejada (jotego) for his FPGA recreations last year and this year. The ones you mentioned are included in his work "942, 1943, Commando, Black Tiger"

He was trying to do all of the pre-cps1 hardware that had something in common with cps1. Like some games have the 384x224 resolution. Some games have the same sound chip. Etc. He recently finished CPS1 and is doing some other stuff while he works on the DSP chip needed for qsound.

This is all done at the logic level because that's how FPGA stuff is done. He uses the "many files to implement a thing" approach that all of the professional ic designers favor. It makes it hard to read for me, but maybe you can do better.

This is his main repo: https://github.com/jotego/jt_gng

The video hardware (and other things common to multiple games) is in here: https://github.com/jotego/jt_gng/tree/stable/modules

And he's on twitter here: https://twitter.com/topapate/
