Bug explanation:

When loading into an NTSC backup game on a PAL PS2 with a PAL entry point game, the loaded game has a sort of green shifted color palette, and the screen is also incorrectly positioned, making it so the top parts of the game aren’t visible. I have confirmed that this issue doesn’t occur when loading into a PAL game, nor does it occur on a PS1.

Hello. Thanks for the bug report. I will be closing, though, since it is a duplicate of #25 - the PS2 will not let a PS1 game (at least without some dirty tricks I've not tried to uncover) to change the video mode. Changes to PS1 video mode registers are totally ignored.
