Hi, guys. I just today received my RetroTINK 2X from Mike Chi directly, and I’m seeing the same problem with white flashes.
While I suck too badly at Super Ghouls ‘n Ghosts to check the lightning on its second level, the problem is pretty obvious in Star Fox 64. It happens a couple of times when entering Corneria, and every use of smart bomb on Sector Y results in the screen dropping too. I assume it’s the combination of the black background and the white flash/explosion that triggers the ESD protection.
For the record, I’m running RGB from my consoles through a YPbPr transcoder to the RetroTINK 2X.
I’m happy enough to mod/fix mine if somebody can spell out exactly what needs to be done. I’ve been waiting almost three for this thing, so I’m keen to get it sorted ASAP.
