Half Byte Loader SVN Changelog:
r100
2010/09/08 (Wololo)
- Adpated the code to J416's Exploit in minna no golf, Freddy's Exploit in
Everybody's golf, and Wololo's exploit in hotshots golf. Adapted by JJS and
Wololo
-- This is majorly untested, but I'm afraid of losing the many code changes
involed here. I basically tested this on the patapon exploit and the hotshots
exploit on a psp go 6.20
-- This improves HBL portability, although lots remain to be done
-- This officially makes HBL compatible with OFW 6.30 and 6.31

I hope I'm not forgetting anything, this is a major update ^^;
