Half-Byte Loader for Patapon 2 (up to OFW 6.20)

Important announcement

I am not supporting the HBL for the Patapon exploit anymore for now, and this page will not be updated anymore. For the new HBL versions, please check the HBL main page. The information below is outdated but remains for archive reasons.

What is it?

Note: although HBL might still be useful to some people, we now recommend to 6.20 users that you use a Homebrew Enabler which will enhance your experience.

This page is for HBL on the Patapon2 exploit. This exploit works for PSPs on firmware up to 6.20 included. If you have a firmware higher than 6.20, please go back to the HBL main page and select the version that matches your firmware
This page is the official Download page for Half-Byte Loader. If you have questions please check the FAQ. For the latest news about Half Byte Loader, check the HBL Category on this blog.
Half-Byte Loader (HBL) is an open source Homebrew Loader for the Sony PSP. It allows to play fan-made games on any PSP up to firmware 6.31. HBL allows to run emulators for the Game Boy, Game Boy Advance, Nintendo 64, Sega Megadrive, NES, Super NES… and many other applications.

On this page you will find my own works related to the HBL: downloads for the latest version, patched games that improve compatibility, the savegame necessary to trigger the Patapon exploit, and other cool stuff.

More Info

HBL is a work in progress and sometimes it might fail to load your favorite homebrew. However we believe it is harmless for your PSP and I personally test my work on several PSPs before releasing it. We are also confident that this program cannot “brick” your psp and it will not void your Sony Warranty.

HBL is open source, the compiled versions I provide are a compiled version of the sources available freely here

When my friends give me a link in my msn messenger, it opens up firefox and it works fine, I’m able to browse the internet normally. What do I do? I already uninstalled and reinstalled it..
