I had the same problem with the rock band demo (requires 5.03+) since I have CFW 5.00 m33-6 on mine. Found a prog called NP decyrpt which runs from my psp and used it to decrypt the demo. Was strangely like 2.5x the orginal size after that but it works
If your running 5.00 M33-6 boot into recovery menu (right trigger whilst turning on psp), change USB mode to flash0 and "use version.txt" to enable. Then reboot psp, use computer to navigate to flash0/vsh/version.txt and change "release:5.00:" to release:5.50: , reboot and resistance demo works fine (presumable along with any other "Minimum firmware" demos. I know this also works for the final fantasy psn download.
I have done this myself on my psp "fat", and it worked fine, but messing with flash0 can end up with a semi-brick - so at your own risk etc etc....
The game is officially out in the UK on Friday and I'm really looking forward to it as I enjoyed the demo a lot (I'm a massive fan the "real" Rock Band game, which probably helped). I think I'll just start on Easy and work my way up.
I liked the game, but being into thump along electronic stuff, without the interaction of guitar, not enough to push me into a must buy territory. Certainly not with the huge amount of games coming out in the near future for the PSP
