Apologies for reopening an old topic, but it looks like this was never resolved and I’m exhibiting the exact same issue on my new SD2SNES Pro. I thought that by reviving it and sharing video that perhaps additional troubleshooting could be done for myself, OP and anyone else seeing it.
See below video, anybody else experiencing this? Some people appear to have fixed it by disabling in-game hooks, however for me and OP that is not working.
https://youtu.be/AuiWbzxyiqMUsing latest 1.10.3 firmware on a brand new SD2SNES Pro
In-game hooks are off
SNES is 2/1/3
SD2SNES Pro passes diagnostic firmware and the console passes the burn-in rev D test.
Recently cleaned pin connector of console with a credit card, 99% isopropyl on a microfibre cloth and canned air.
ROMs sources from a no-intro compilation.
As a side note, the reason I’m mildly concerned is that the other night while playing DKC 3 I noticed some sprite corruption during the barrel shield level (corruption of one of the barrel shields while climbing a rope) It fixed itself once it was off screen and I went back so it could be nothing.
