This is a simple to use and add to any software you develope for the PSP device, it is also works well without any issue of anykind with BenHur's intraFont so here is the SXLibary (coreXLib Replacment) that I mainly coded for myself.
I will be, now on! sharing my code online to any that would like it.
Please note that this library has just started and so will grow overtime and the GUI functions and Transition functions were not ready to be fully usable so excluded them untill ready.
Mac OS X / PC support will follow soon after v1.0
Simply add sxlib.c & sxlib.h files to your project and download a copy intraFont v0.26 from http://www.psp-programming.com/benhur/
