I think you should release it all. It would make the memento team lower their 80$ price tag, Hell, maybe they would even release their memento fw to all types of memory cards seeing as how they wouldn't be making any money anymore.:lol:
Making the game think there is PS2DVD in the drive is very easy... But unfortunately game itself is not the problem. I tried many things, and there doesn't seem to exist a solution that would make burned, not patched ps2dvd discs to not be rejected. Anyway, I have a solution that makes the dvdv patched games running just fine, as well as homebrew apps (and it's much better than memento, since it works with all the games that memento has problems with). But I haven't decided yet if/when/what form it will be released (though, I think at least the homebrew version will be released soon, once the gui is done - so all homebrew apps that use cdvd should be able to read dvdvideo/dvdvideo patched discs without any changes to their code... I'm not yet sure about the games - well, it's legal by itself, because it's done completely with homebrew ps2sdk...).
