@marqs – Massive thanks. No pressure, I’m just glad it’s still on your radar. 🙂
@paulb_nl – Thank you again! And yeah, the mask is definitely not behaving the same way in every mode. Hopefully there will be a work-around for the H centering being off.
I’d personally take a fixed optim. 320p/256p over a misaglined 480p, mainly because I’ve never seen a PS2/GameCube/XBOX game displaying any colored (or non black) overscan area, so I don’t even use H. mask with those systems, in general.
Huge thanks again, guys. ^_-
