i played a few of the SM recompile port anons posted here earlier, it isnt bad and is 1:1, plus 60 FPS and keyboard is more responsive than RA, i had to "improv" a bit with reshade due to the aspect ratio this port has.
as they said above, wish someone could pick this up and update it to work with rom hacks and the Widescreen patch.
SM on PC is still quite huge, but Prime trilogy would be the tits.
