uOFW

The unofficial Official FirmWare, a complete latest PSP firmware reverse engineering project.
Project page: http://uofw.psnpt.com/
Doxygen documentation: http://uofw.psnpt.com/sdkdoc/
For more information: http://dev.psnpt.com/redmine/projects/uofw/wiki

Getting started

In order to contribute to uOFW, you need advanced knowledge in MIPS ASM and C. Some good MIPS ASM
online resources can be found at: http://www.mips.com/products/product-materials/processor/mips-architecture/
MIPS ASM Instruction Set Reference: http://math-atlas.sourceforge.net/devel/assembly/mips-iv.pdf

In addition, there is a nice MIPS runtime simulator and debugger which can be found at:
http://courses.missouristate.edu/kenvollmar/mars/

The next step is to improve your reverse engineering skills (if needed). We suggest reading the
following excellent guide about reverse engineering for the PSP:

If you have questions, don't hesitate to ask us!

Additional Information

While you reverse-engineer parts of the PSP's kernel, you may will find yourself in a position where you would like to know more about how Operating Systems work in general. We suggest to check out the following webpage: http://wiki.osdev.org/Expanded_Main_Page
