Current state of the PSP world (custom firmware)

[Harrison]

It's not that likely that anything would go wrong during downgrading/upgrading firmware. As long as you first charge the PSP to 100% battery and have it connected to the mains power throughout the process there is little that can go wrong.

As it is a new PSP you might have quite a new firmware version on it. This would require using a copy of the Lumines game. I've not tried this downgrader myself, but might shortly to downgrade my girlfriend's PSP so can let you know how it goes.

Lumines doesn't look like a game I'd usually spend money on but if a lot of people are buying it simply to use to downgrade perhaps eBay might be flooded with them and I can get it cheap off there.

It's probably worth buying if it allows me to sample games before deciding which to purchase. How does it work once you have the custom firmware? Do you put the ISO image on a Memorystick along with some application to run it? Am I right in thinking a 1GB card will provide enough capacity?
