Any way getting Cuse of monkey island to work stable?

[STASKO]

i Have Firmware 3.03 OE ( something like that)

And i have the whole game on my PSP now!

But i also saw when i used The demo looked better and that The Demo was also playing much faster!

I Use Scumm 0.9.1 but it makes Curse Of Monkey Island impossible too play! (You can but it is very very slow)


- Speech is slower then the images!
- Very long loading times between the text of people
- Long loading times for switching area!


What did happen?? Why cant you play this game?????
