1 second freeze/stutter

[satur9dreamer]

So i have been playing Star Ocean : First Departure and Persona 1 on ppsspp.

I have owned these games physically for many years so i had no qualms in regards to finding iso's for them.

i had no problems at all playing both of these games for a couple of days.
it all looks great, sounds great and plays great. it's like playing on an actual psp aside from the obvious resolution that looks sort of stretched, but that's natural.

anyway, suddenly the games starts to freeze for exactly one second and then starts again. everything stops, from sound to gameplay and then resumes.

this happens approx. every minute or so which is now ruining my experience.

but i cannot understand what is happening. i played for over 20 hours without this happening at all.
now i am utterly unable to enjoy playing these games on ppsspp.

i have tried to tweak with the settings, but i am honestly not very savvy with that kind of thing. but i cannot see how settings would matter as i did not fiddle with them at all during the many hours i played without any problems at all.

...anybody have any ideas?
