Hey my name is Jake and Id really like to start coding for psp, I have some background coding in basic and c++ and Id like to know what software Id need to start coding, I was searching the forums and I found some outdated news related to the gta exploit. What would I need to began coding a new application, are there and guides or anything?

Has some tutorials related to psp programming. I was going to start programming in general on there, but after the first tutorial I realized it would probably be better to learn general C++ first so I know what it all means.
