I have a feeling you’re pulling my leg here. 🙁
No, not pulling your leg at all. I’ve had my PSP for 4 years and haven’t attempted any kind of modification..
FYI: CSO is compressed ISO.
Custom Firmware allows you to mod your PSP so to play downloaded games directly from the memory stick. Downloaded games normally comes as ISO files but I normally compress it to CSO formats, which custom firmwares also supports. Although arguable, I personally feel CSO formats load faster, probably because of its size. Others argue that CSO should take longer to load because the PSP needs to decompress before it can be processed. That makes sense too.
The purpose of upgrading firmware is to ensure the latest games can be played. I normally do not upgrade until I found a game that I cannot run. The last time I upgraded was over a year ago, at the time upgrade to v3.52 M33 Rev2
How big is are such files usually? My MS Pro Duo is 2GB and a quick look at my PSP reveals I have firmware 2.81. Any suggestions on how to ‘get started’?
Besides ISO files, does a custom firmware support avi divx files? I didn’t enjoy having to convert files to mp4 format just so they can be viewed on the PSP.
