A quick update on the game's status: I've been playing with r7081 since that fog problem started, but today I've upgraded to r7458 and was glad to find that there seem to be no graphical glitches now, don't know when the fog was fixed... Also, the game's about 15-20% faster than with r7081, which is great, especially when in CPU-intensive overworlds of Chozo Ruins and Phendrana Drifts. So far I'm at 46% of the game and still had no crashes, except sometimes when using quicksaves, but that's expected...
