So, I've earned a fat wad of ca$h, and since I already have DSLite with R4 + 2GB Japan Kingston and an EZ 3-in-1 I was thinking of buying the PSP. I'm thinking of buying the Slim & Lite version. And here are my questions: 1. Are there any specific downsides to the Slim & Lite versus the old Fat one. I know the UMD-hatch is different (simpler). Is this a problem? 2. Are there any diffrences in Firmware betwen S&L and the fat version. 2.5. Are there any diffrences in Firmware between a PSP from Europe or a PSP from the US? I live in Europe (Sweden), can I use US CFW? 3. If i get a Pandorabattery from DealExtreme will I be able to upgrade and downgrade my PSP whichever way I like? (I've read about alternative ways, such as modifying an official battery, but 10$ for an extra, already modified one seems okay to me) 4. Is 1.5 still the only FW that will play ISO's or have the always jolly, hardworking hacking community arranged so that you can run ISO's with the latest CFW? 5. Any good forumthread recommendations? 6. What is the easiest way to modify Firmware? The Battery hack with the restoringconsole or something else?
