Disgaea 2: Dark Hero Days

[QuizmasterBos]

I have encountered two issues while playing both Disgaea games on ppsspp.

First of all, this happens quite irregularly, but when a combo goes on for long enough (I suspect about 8 or 9 in a row) the game would crash. Not that big of a problem, luckily.

The other happens more often though, but far more in the second game. During cutscenes with voice-acting, the voices would randomly cut out, with the rest of the sounds still playing. This happens in about every cutscene in the second game, but doesn't happen as often in the first game. It appears to happen during particularly long cutscenes (such as the first one) or when you've seen a cutscene, play a bit of the game and do another cutscene.

Strangely, it appears to fix itself (briefly) when I reset the emulator with ctrl+B.

I haven't heard anyone else about this, so I suspect it's an emulator issue, but I can't find anything that would cause this to happen. Does anyone have any idea?

My specifications and settings are:
OS: Windows 7 64-bit
Version ppsspp: v1.0 64-bit

As for the emulator settings, these images ought to tell it best.
