PS3 Assassin's Creed Brotherhood Save Editing

Well, I wanted to post in an old thread I was participating in but my account seems restricted. Just wanted to let everyone know I've managed to decode the OPTIONS files for ACB. It's got three sections compressed with a unique lzss algorithm with an ADLER32 checksum in their headers. When decompressed it allows for adding the uplay rewards to your account. I'm mapping it out right now and will post more when I get this up on my github, but hoping to break open the actual save file to add the unique facebook capes next.

Nice. I guess this information could be of interest for @bucanero and Apollo Save Tool

Uploaded current progress. It's missing the PS3 checksum that I assume exists, but I'll see if I can figure that out real quick for a quick push in a moment. It was just easier to test it out on the PC copy which is missing that checksum.

It also looks like a lot of the work also flows into the ACB save file itself so that might turn out easier than I thought it'd be.
I'll wrap it up in a pretty GUI once I have the rest of the process figured out.

Note: some of the mapping is incomplete as I don't have access to multiplayer to test the character unlocks. Does MP even exist anymore on any platform?

I've split it into two different repos for right now.

I have full roundtrip on both PC and PS3 OPTIONS files with the majority of the uPlay unlockables mapped out. (PS3 untested at this moment)

I have full roundtrip and the ability to unlock both Medici and Venetian (facebook capes) in the GameSave for PC. I also have most of the entire save structure decompiled and documented out if anyone is interested, but I'm personally not going to go much further than changing name or unlocking the capes. PS3 unlocking will be coming soon.

Going to finish work on this AC:Wild World letter injector to decompress before I finish up the PS3 roundtrip and then package it all together.
