Vita Half-Byte Loader (VHBL) 2.61 : Hack PS Vita avec Half Minute Hero

Hey guys,
with PSVita 3.00 firmware update were apparently quite several exploits (include private ones too) patched, including the private exploit of mine I’ve been using since Everybody’s Tennis was published and fixed.
Indeed Zer01ne used his Uno exploit until it got public, and lately decided to use mine too but unfortunately for him especially, he told me it’s been patched on 3.00 !
Damn Sony, they probably watched my crash logs / PSN game purchases who knows lol.

The game is Half Minute Hero, available in EU / US / JPN PSNs, with exploit working until firmware 2.61, and VHBL too.
However I didn’t update my VHBL for it since a long time, indeed I’m only using it to load eCFW since then.
To make this VHBL usable someone would need to merge it with the official VHBL latest changes, so that files respect the 8.3 CMA name convention and have uppercase file names. I have no time for this ;)
jigsaw also found this exploit himself after me, and we also had an agreement to keep it private, but since Zer01ne verified it’s not usable anymore on 3.00 it’s no use not publishing it anymore.

VHBL info :
This VHBL uses a special GPU unlocking method using sceGeListUpdateStallAddr on the game’s main qid, indeed without it the GPU won’t draw on the screen somehow, making VRAM direct write working only (without this “fix” sceGeListSync and sceGeDrawSync never end to be precise).

Files :
- Binary loaders for EU / US / JPN games : they will load & execute the H.BIN file you put in their save folder
- VHBL r147 for EU game (to make compatible with new CMA 8.3 file format)

Coldbird is to thank for crafting the US / JPN exploit payloads though :)
Have fun ;)
