Developer's note:

This new revision brings 2 major changes for the user: First, the menu is now a standard eboot. It means that if you are a homebrew coder, you can create your own menu with the usual SDK tools, and are not limited to the Patapon SDK anymore. Second, HBL is now able to come back to the menu once you quit a homebrew. This function is highly experimental for now, so don’t cry if the second homebrew you run doesn’t work as expected… This feature can be disabled by setting return_to_xmb_on_exit=1 in the file hbl/hbl_config.txt. I still recommend revision 85 for now if you are looking for maximum compatibility and performance, but revision 91 sure has some benefits

I especially want to thank Noobz and Fanjita, as most of this new code is a ripoff of their eLoader. (If you have never heard of the noobz eLoader, you missed the PSP’s golden era )
