There is a question if this display supports other than 60Hz video.
as an update, 50 Hz seems to be working for most cores, although, i tried a european mega drive rom, "Aleste" and i got a blank screen, but when i tried the NTSC version "Musha" it worked just fine, but it could have been something else... i didn't really dig into it, since i'd prefer to play 60 hz when i can.
I tested Terranigma on SNES, and that worked just fine at 50 Hz.
