I've tried SHA-1, TIGER and RIPEMD160. You could try others yourself if you want to, but I'm having the feeling here that not very much people are comprehending what I'm saying. Maybe I'm just wrong, plz correct me if so, but I dunno if someone really understand what I mean if I'm talking about the NULL-block, or other parts of nk.bin's main structure.
Maybe I'll have to take some screens or document everything a bit, so (lazy) people understand what I'm talking about. If I'm totally wrong here, plz say it. Thx
iSE:
Some of us know what you're talking about :P. Though I wouldn't say those who don't are lazy, more have not come across this before and just haven't had any experience with it.

We understand you fine - remember that we have reverse engineered a few other players before this... But I figure there are more than one way to run these hash algorithms on the data (like order of data, range of data, with or without padding etc) so I don't see how any random test-shots can exclude any particular algorithm until more details are discovered.

Yes OK, but I wasn't talking about the hash algorithm cracking; I wasn't sure that you(plural) knew what I was talking about when I mention the NULL block and stuff...
And if I insulted anyone, I'm sorry for that; it wasn't my intention to do so... :)

In the past, how did you figure out more details? Is it best just to keep trying codes and seeing if the match up? To me, that sounds like a lot of guessing.
