Grandia constantly streams from disc and is very picky with burning speeds, your lens being tired don't help either. To have a proper working Grandia burned disc you need to burn it at 1-2x max (you need an old burner), or at least new lens to alleviate these problems.Hi. Finally got a Pseudo Saturn Kai cart for my launch model US Saturn. I have the original Japanese game, and that plays flawlessly. I burned disc 1 of the English patched game on a Taiyo Yuden lacquer CDR. Other burned games play fine, but English patched Grandia frequently freezes on a black screen when accessing the save menu or items menu (music continues playing). Especially the A button menu, seems to freeze 9 times out of 10. Those are the only times the game ever freezes.
I'm still using my original laser lens, and it's kind of flakey, but works for other games. I just found it odd that it's always the same particular actions that seem to lock the game.
