PSP analogue nub (noob question, sorry)

[StolenDiagram]

Ok, just got started with scummVM this morning and gave BaSS a quick try. Conversion wise, the game is perfect and am looking forward to giving my favorite lucasarts games a go once I convert them.

I was however wondering if it was possible or not to improve the analogue nub's sensitivity at all? Playing BaSS with it seemed a little slow and could make some puzzles overly difficult to complete.

Thanks for any relevant responses

Would also add that for some reason, I can't manually save my game - I've tried BaSS's in-game which doesn't work. I've also pressed the select button to try and the X button doesn't work
