Just like bootsector, the last working version for me is SNES_20190204. Something happened between SNES_20190204 and SNES_20190225 to cause this I assume? As the atari forums are gone, so is the change log that Sorgelig maintained so I can't see what he posted. I took a look at the commits between those two versions and there are a lot of changes suffice to say.

Feb 4, 2019 (This commit happened after the release I think?)
- Reduce audio taps.

Feb 11, 2019
- Fix Vsync length

Feb 12, 2019
- Merge pull request #35 from paulb-nl/vsync

Feb 23, 2019
- Merge pull request #14 from MiSTer-devel/master

Feb 24, 2019
- Rewrite the muxer of chips.
- Minor update.
- sys: update scaler, scandoubler. User port definition. Remove VIP.
- Merge pull request #36 from srg320/master
- SA1 support

Hopefully this helps. I do have a new de-10 nano on the way so I'll report back my findings when it arrives.

When I had issues with my SDRAM module, even though it passed memtest, it caused graphical glitches on Super Castlevania once I updated to SNES_20190719.rbf but the build I updated to previously worked fine, SNES_20190609.rbf. I'm guessing maybe the memory speed or area usage changed which brought out the wonkyness of the SDRAM module? Once I replaced the module, all was good. Though, my issue is probably not related to this issue since it affects much more users, figured I'd mention it to try. Not sure if this works for 128MB, because I was using 32MB at the time I think, but do you have issues with SNES_20190609.rbf ?

I can confirm that the HDMI port definitely has issues regarding 5v. I'm using a Moread HDMI to VGA adapter for direct_video output which includes a micro USB port for optionally powering it externally. I tried using it that way once and I think it sent all that 5v straight back to the DE-10 Nano because it lit up like I had powered it on (the board was not plugged into the wall yet, just the adapter). The board also gave out a high pitched whine like a CRT. Needless to say I unplugged it as soon as I could and never tried that again haha
