Birdman has a new version of his font pack ready for use. It has well over 102 custom fonts for your PSP's xMB. Birdman1's font pack allows for easy installation of fonts. Just be sure to read the included readme file for additional information and needed precautions.

It isn't really that hard to install the fonts, the readme file had this to say:

STEPS:

1. Pick a font. Open the fontmod folder inside and copy the file inside.("ltn0.pgf")
2. Go to the fontmod folder in the Root if the zipped file. Place your recently copied font in there.
3. If it asks you to replace a file say ok.
4. Place that Fontmod folder with your font you picked in the Root of your psp's memory stick.
5. Use either X-Flash, or some kinda or program that can edit your fonts.
6. Once you run that program you should have your custom font.

If this somehow fails you can check out Birdman1's youtube profile. He has instructional videos there.
This font pack was based off the hack originally developed by Skylark, FreePlay and TeamOverload.
