Metal Gear Solid: Peace Walker

[blutar]

Hey guys, I encountered a strange problem in this game today.
I quickly wanted to finish extra ops 17 (Fulton Recovery mission), and something went wrong here. I have a quicksave just before the end. When I finish the mission, either one of the following things happens (depending on how I mess around with the settings):
- it locks up after a second of loading my quicksave, only task manager helps me out - this is when I disable the JIT.
- it crashes immediately after the mission successful message, but before the results (you know, the default windows ëncountered a problem, look online for a solution, close the program) - this is when I run all default settings that worked until now.
- it goes to the results, it saves my game, but then it just presents me with a wonderfully emulated and rendered black screen. If I restart ppsspp, it tries to load this save game and just stays black too, never showing me the msf base menu. - this is when I disable Fast Memory

I use 1.0.1, happens both in 32 and 64 versions. I am able to return to mission select, but no matter which mission I select after this, it gets the same issue. Anyone have any ideas?
