Firmware 1.0 -> 1.5 ?

[Fr0en]

Im having trouble with installing anything on my PSP.

So i heard that 1.5 can run the most or i could emulate a higher firmware on the 1.5.. dax wont work on 1.0..

Is it wise to use this?

What would you recommend? upgrade to 2.0 and downgrade it? or just install 1.5 from the link above?

I got a 1.0 jap PSP.
