Repair Header

[harumazzz]

There are multiple things we can do with the header. Example: RSGP header are very easily to be broken, but that's not impossible to repair. In the first place, they trying to change compression flag 0x01 and 0x03 to an random hex byte number, but now it can be more corrupt since the entire header has been corrupted. Also, 1BSR Header which is known as the smart path has the version number can easily be changed from 04 to any other number. Try to make the tool recover the magic by return it to 0x04

Compression flag will be repairable again. (I'll re-implement the functionality for that)
The rest of the header too.
The version number isn't used by the game, so repairing will simply fix other tools.
And I'm not sure how this can be figured out (pvzfree vs. pvz2 ipad3):

Hey guys, how can I fix the headers?

[nineteendo]

I don't know.

[denny4-user]

@Haruma-VN Does he know?

[denny4-user]

I understand the principle itself, but I don't have the programming skills to write such a script.

[nineteendo]

RSB1 is a proprietary data format, that the modding community tries to reverse engineer. If it was simple, it would already be implemented in PyVZ2.

I'm not saying that I'm a better programmer than you or others, I just want to help you if I can.

OK, but right now I'm improving the rton2json and json2rton conversion. As well as implementing json patching:

There's a lot left to do with these arguably simpler data formats.
