New Crash Alert!! Teh Gelnika crashes when you enter it with the hi-res cloud. Even worse, its doing it in Win98, so this isn't another XP-related annoyance.
But, I have a theory for why it's crashing there.
Based on what I've read in
this thread, it appears the game will crash if one of the player characters somehow gets placed outside of the "Walkmesh" (the area on the field screens that's defined as where the characters can move around.
Now, when you enter the Gelnika, you're placed on a latter, and probably extremely close to the edge of the walkmesh. The normal models work fine because they're small enough to not go "over the edge". With the hi-res cloud, it could be that the increased size is just enough to spill out over the walkmesh, triggering the crash.
As far as the other crash areas reported are concerned, something similar may be going on there as well. I don't know if fixing the alignment of the field backgrounds and the hi-res models will help, but it could help fix the problem -- or, for that matter, modifying the walkmesh data to account for the increased size of the models.
