@StarLord29 Hello guys, I've just been given the info, these are all Pademonium Cinematics prods...And he only develops on Launchbox! :(

It is absolutely necessary to bring him here this guy has amazing talent !

From what I understand he builds his own media from A to Z to animate them then...I just came across the Zelda ultima, it's in French but jesus marie joseph it's magnificent !

another realization here, and it's just as crazy ..

Ok - I've got SOTN basically playable.

Using the retroarch overlay config GUI (select+X in game) I set:
frameskip to 1
custom viewport width 1440 (x3)
custom viewport height 816 (x3)
integer scale on

other settings:
hw biliner filtering - turning this to off makes the game look significantly better on my big flatscreen from apx 3 meters away, but doesn't seem to impact performance (disclaimer that I prefer a pixelated look to a blurred look for my scalers)

other observations:
loading savestates seems unstable until loading a regular game save. not sure if its related to my settings changes or not.

I have the same issue. Do you have resolution for this problem?
