Having sorted out problems installing the toolchain an libraries, I have moved on to programming. That is a problem in and of itself. There seems to be very little to no information on PSP specific functions anywhere, and the only set of tutorials (psp-programming.com) I can find approaches the graphics tutorial by giving you a couple of source files instead of teaching the actual PSP functions. The source files aren't even well commented, except to comment on the parameters of each function, leaving you to figure out how each function works by studying the code.
