We can add text and a border to the image after it's off the PS2, but that's it?
Editing the color balance, etc on the TV is fine, but what looks right there won't always look right once it's in the computer. If we aren't allowed to do any curves/levels/color edits, it's probably safest to just leave the PS2 renders alone.
The thing I don't get is we can't even crop it differently? MS Paint can crop, so I'd assume cropping is something most everyone can do...
