I can confirm that using the dotsarecool tool to customize the menu does NOT work currently. It results in garbage at the top. Despite that and the config loading issue, wow, what an update! Star Fox feels almost right now in Normal mode, and in Fast mode, it is pretty crazy.
I think I will do a test capture in a few minutes comparing the cart and the SD2SNES side-by-side to investigate further, but I will note that in normal mode, there is still a wee bit of excessive delay between the second and third ship boosting off at the beginning of level one. It seems better than past revisions though. So I think Normal speed is still slow, but getting closer to where it should be!
