Thank you ever so much.
You have no idea how confusing all of this can be to someone as stupid as myself.
I have a 1080i HDTV but the Xbox can only send out 790p, and then there's a 16:9 or 4:3 setting on the TV, not to mention the 10:11 ratio in the emulators that can be used as well. And then you have Cospefogo's formula of subtracting 2 pixels but that was on CRT televisions.
Put those all together and I simply get stumped.
I just want these emus to display on screen so many times it's original resolution with no filters, if that makes any sense.
Keep it old school but on a new screen.
Anyway, thanks for the PM.
I've got a great night coming up for me now.
