I don't own a PSP yet. I just have games:
Lumines
Ridge Racer
Syphon Filter
Virtua Tennis
...and I want to go after Daxter, Every Extend Extra, Exit, Killzone: Liberation, Loco Roco, and Metal Slug Anthology when its released.
So my questions are:
Is it worth going after a 1.5 PSP? I like the idea not having to carry the UMDs around, and just play the games off of one or two memory cards. Other than PSX, I'm not really in to emulation. Portals sound pretty cool, as well.
Is there an advantage to having a PSP with the most up-to-date Sony firmware? Are there features that you'll find using Sony's firmware that you won't find in homebrew hacks?
Is it difficult to use homebrew applications? I'm talking about converting DVDs to PSP format. Transferring games from UMD to the memory card. Converting PSX games to be played via emulator. Are there places with decently written how-tos to be able to figure this out?
Thanks!
