The last public release was almost 2 months ago, it was an entry for the psp hacks competition.

This time it's an entry for the PSP Updates Homebrew Contest. This seems a small release but it's not.

This version has 105 new/changed features (NOT 105 NEW FEATURES)
For this version I created my own file format which is .upt. It is used by the network updater to know the information about the latest update which is hosted in consoleworld.net's server.

You can understand now, why it took me almost 2 months to finish this.

The readme was re-written ALTHOUGH IT DOES NOT EXPLAIN EVERYTHING. The wiki has more information than the readme, keep that in mind.

This time me and my beta testers decided I am going to create a few chat rooms for instant help.
Check this thread for more information.

NervOS Official Forum here.

Thanks to my beta testers and to everybody who contributed to this project.

If you find a bug, report immediately but report it in the official forum please.

I hope I haven't forgot the the splashscreen :P

If you want to give some suggestions, post them here.

This will not brick your PSP if you DO NOT shut down the psp while installing or do anything stupid like that. This only uses flash1 and memory card so it will not touch flash0.

@Nacos, I did not make the image.
@V1, it was removed from the control panel, it is under applications now.

I did not add UMD video yet as my feature list was deleted from my forum so I forgot to add it :(

No, not from you.

105 different things adjusted and/or added. I stopped reading at like 35. :P

Nice work, been waiting soo long for this.. Thanks.
