Shortly after the game loads its title screen, Medusa crashes. I've attached the last logs I can get before it happens:
The version is 9379290 (32-bit since the 64-bit nightly refuses to open), but the bug is also there on medusa-a1, 64-bit.
To be precise, once the game shows its title screen, both the game and the GUI start hanging (good old "This program is not responding").
I'm not really Windows GUI-savvy so I don't know what usually triggers that kind of behavior (infinite loop?), but it does affect the whole emulator and not just the game.
