uPSPD (unofficial PSP documentation) was a project of making a full documentation for PSP.
In an effort to avoid documentation fragmentation, the contents to the wiki have been moved to the PSP dev wiki and this repository shouldn't be used anymore.
The old documentation remains in the "Wiki" tab of this page.
We uploaded useful information to our Github repository: http://uofw.github.io/upspd/docs/
Furthermore, you can find useful information to complete this documentation on these sites:
- PSP Dev Wiki - the most complete documentation wiki as of now
- ps2dev.org - archived, another website and mostly forum which holds a lot of information too
- wololo.net, a blog and forum about more PSP stuff
http://mrmrice.fx-world.org/vfpu.html, with information about the VFPUhttp://wiki.fx-world.org/doku.php?do=index, with details about the VFPU instructions and registers- Kirk engine, a project of imitating KIRK's behavior, holding information about how it works (also available here: https://code.google.com/p/kirk-engine/)
