I'm interested in which firmware everyone is running on. It would be very helpful if you could reply to this post with a) which model of PSP you're using ('fat'/slim, revision # if known) and b) which firmware you're using.
I have two PSPs. I have an original Japanese PSP with v1.00 firmware which I use for development, and a UK PSP which usually runs the latest official firmware (v3.72 at the moment.)
I'm interested because I want to know if anyone still requires the v1.50 (kxploit) versions of Daedalus that I release. I also need to figure out if it's worth my time getting a slim PSP for developing with the v3.xx+ firmware.
