I haven't touched my PSP in months and I really want to get back into playing it but at the moment I have custom firmware 3.52 M3 and I'm not sure if it's compatible with the newer (UMD) games that require the newer firmwares.
I have the old, fatter PSP. How can I upgrade to the latest custom firmware that works with the newer games? I'm on a dial-up connection so I'd rather avoid downloading things as much as possible but I realize there are going to be 20MB+ updates involved in the process.
Where do I start? I can't remember anything from the previous time I installed custom firmware but all I know is I'm on 3.52 M33. Should I upgrade or will the newer games like God of War: Chains of Olympus work with this firmware?
