Final Fantasy 4 the complete collection crash

[Jeegsawk]

Good morning everybody,
this is my first post, let me extend my compliments for this fantastic community I have been reading for a long time now.

I searched the forum but I am not able to find any help so after a few years I am writing for the first time myself...

I played the game in the subject until first time you can leave underground by flying ship.

Whenever I pass through the volcano to reach surface ppsspp crashes without any message.

I used to do it without a matter with one of old ppsspp versions (too bad did not wrote which one it was).

PPSSPP 1.8.0 (had same issue with 1.7.5), FF4 CC NTSC
Anybody have the same issue?

Any suggestion? Shall I downgrade ppsspp and try again?
Thank-you.
