Well, I'd tried it without the DAC sound chip on. Obviously, some sounds go away (I'd recorded NBA Jam). Unfortunately, it did skip, but it was much further on in the recording, instead of happening right away, so that's good, but I think that I might have figured out why it's been skipping (I'd even seen it skip, while I was recording).
I'd put the game on slow motion so that I could steal the ball, and make a slam dunk, as usual, but what I had done at some points is turn off slow motion while it was still recording (not a problem, you believe), but...when I turn slow motion back on, the recording game pauses, so I'd press it again and it'd go back to normal speed (so that I'd be able to press it again to have it go back in slow motion). What I'd noticed, from then on, is when I'd change it to normal speed, slow motion would still be checked off, as if Gens 9a had thought that it was still on, when it really wasn't.
It'd still work like normal, but some of the time, when playing on normal speed, slow motion would be checked, as I'd just previously stated. If anyone else has noticed this happening, then inform me, because if it's happening to others, then it might be a good idea to fix this for the next version that could be released.
