Samsung QN49Q70RAFXZA 49″ 2019 Q70 series
Tested Genesis & SNES (NTSC)
GEN (model 1 VA6 stock)
Passthru/Lx2/x3/x4/x5 works (incl. all resolutions on x5)
SNES (1-CHIP-01 stock)
Passthru/Lx2/x5 works* (*caveat, temporary black screen, 1-2sec on specific portions of the Mystic Quest demo in the Bone Dungeon and battles when Blizzard is used, guessing this is due to jitter)
Lx3/x4 do not work
Will test & repost after de-jittering the 1-chip.
