Nothing of which I'm aware, other than PinMame emulation.

When Gene released the Big Bang Bar remake I tried VERY hard to locate source code for the game; Gene wasn't aware that he had it, and I was never in a position to dig through his warehouses to look for it. I contacted a few Capcom developers from that time but none had access to the source code.

With the help of a few others I was eventually able to come up with disassembler output of the game code, and was able to patch in a very small change to the lamp matrix table so the game would recognize the credit light added to the apron on Gene's remakes (which the software thought was "unused"). It would take a lot of effort to reconstruct source code from the disassembler output, and I wasn't interested in spending all that time.

While digging through the disassembler output I did find a few copyright strings that identified the compiler vendor ("SDS"); that company was eventually acquired by Wind River.
