from the Readme:

This is a modification of COry 1492s Open Source Nand Dumper.
I cross-compiled on ecplipse and minimalist pspsdk.

Currently, all this does at the moment, (hence the v1), is make a complete dump of the nand.
All you have to do is open up the program, and its doing it for you!!

My future plans are -
1. Have a restore function
2. Have an extras menu, with a currency converter, weather viewer, etc etc.
3. CLean up the menu interface, and add customization and configuration options
4. Complete rewrite, and optimize every last damn bit of code.
