If you're late to the Project4 party, allow Auraomega himself to explain what the shell is all about:
Project4 is currently the only true XMB replacement for the Sony PSP. It completely replaces Sony's XMB, and works directly and independently from the NAND flash. Contrary to the common shell for the PSP, Project4 physically removes the S-XMB from loading, and replaces it with code specifically designed to work all from flash without ever needing a memory card.
The shell has a couple of extras, such as a calendar, calculator, and stopwatch, which might be buggy at this time but will be improved upon in future versions of the shell. For now, think of them as placeholder applications.
Furthermore, Project4 has been made more user-friendly. The configuration file is easier to read, shortcut buttons are now enabled, and there's now some plugin support for files. More information on each of these additions can be found in the linked forum page which details the changes we've outlined here, as well as in the extensive readme file included in the file.
Lastly, Auraomega is once again taking in donations to help subsidize the cost of buying a new computer, as his current computer is on the road to conking out completely. If you like what he's made, feel free to visit the sourced link below and donate to his computer fund.
Once again, thanks to Auraomega for the email, and stay safe on your hiking trip!
