If we count obsolete movies, the total is 345 published runs. Of which NES/GB/GBC account for 307 of them. 345 is ~7.2% of all published runs when including obsoleted. Either way, very good progress. And much of that progress was made just in the last 2 years.
I'm still planning to explore both Genesis and GB/C (potentially GBA too). Genesis is likely what I'll do first, though. From everything I've managed to research so far, Genesis seems like something that hasn't really been delved into much in the public space. There's a few verifications out there; but little to no information about the problems (if any) faced by those people, or what they used for staying in sync. During this last SGDQ, I talked briefly with
numbers about his Gauntlet IV work-in-progress TAS. He described something odd about how some games read controller inputs. Along the lines of games causing the console to poll the controllers multiple times, but not always actually reading their state from memory.
However, based on official documentation from SEGA, the pins on the controller ports are directly accessible in memory. It's just that in order to read the entire controller state, the mode/select pin must be toggled in order to access some of the buttons (there are more buttons than available pins). Whatever the case, it should be easy to detect what's happening using memory callbacks in Lua (assuming the emulator core actually supports that in bizhawk).
And then there's concerns about initial state and all that fun stuff too heh. If it's just a matter of initial RAM, or something like that, it should be possible to initialize state ourselves, similar to
ViGrey's RAM initialization ROM. The Genesis cartridges are extremely simple, even compared to the Atari 2600, so designing/programming a cart for this shouldn't be too hard.
In the mean time, this week I've been catching up on recent NES publications (and some submissions). Verified 9 movies in the past few days. And continuing to grind away at the remaining NES games. Also been working on some tooling projects for dumping Quality-of-Life. Particularly
VeriTAS which has the ability to take a TASVideos Pub/Sub ID number, or a local movie, and automatically run the entire dump procedure (including dumping multiple movies in parallel). It does work,
but it needs some polishing before it's useful for the public. And ViGrey and I still need to finalize the new dump format we were working on last year.
