There is updates out. I have downloaded one of them. But they are packed for 3.60. The tools will probably be a batch file that puts all the updated stuff into the right files and puts the eboot.bin where it needs to go.
Heard some comments here and there about the multi release being a bad dump, with the files still encrypted or what not. Doesn't make sense to me; if a clean retail disc was copied using multiman, shouldn't it work fine? I've never heard much of anything about ps3 game files being encrypted.
Maybe the uploader was refering to the so called pslight pkg 3.6+ signing tools, soon to be released by gitbrew. The uploader of Battlefield 3 stated the same thing I remember.
