Odd Bug for 1.6.3

[[Unknown]]

Strange, especially self destructing. I would suggest checking your anti-virus software - it may show if it detected a threat in the logs.

I would also suggest trying a recent git build from here:
https://buildbot.orphis.net/ppsspp/

This is at least a different (and newer) version that might behave differently, or be detected by your virus scanner differently.

Has it self-destructed more than once? Do you remember which game you last played when this happened - just in case it's somehow an emulation issue?
