How to install custom firmware patches?

I've received a few mails and private messages from some of my friends regarding the installation of custom firmware patches. These patches are actually created by the developer of the custom firmware to patch errors in the original code or maybe even to add new features to the existing custom firmware.

Now, for this short guide, i'll be using the -2 patch for 40.1M33.

1) Download this patch : 4.01m33-2 Patch

2) Now, extract the files from the .rar file using your favorite rar extracting software. 

3) You should now see a folder named "UPDATE-2".

4) Copy that folder, and paste it in the ms0:/PSP/GAME directory.

5) That's it. Now scroll to game, and run the update!

This applies for nearly every custom firmware update out there. Also, these sort of patches would take barely a few seconds to complete.

Cheers!
