I don't know if it's the best place to do that, but at least i know this might interrest some people here. Since wow has been released i got verry interrested in wrinting some mpq viewer, and have finally been able to come up with something working more or less correctly. What i have so far is a library (c#) that should handle correctly every post-warcraft3 mpq archives, supporting only 3 compression formats: PKWare, Zlib and BZip2 (though seeming to be used only by wow patches). It will only be complete when the remaining compression formats will be implemented, but i focused on reading the archives I had access to. Upon that library i created an archive explorer looking like MyWarcraftStudio, and a "toy", wow world map viewer. Both are still missing some features i'd like to add, but my archive explorer should be a great help (at least it has been for me) for understanding fields in dbc files.
I am not sure wether I will continue to work on this, but since it has reached a fairly correct stage of usability, I thought it may be a good idea to release it to the community before I stop working on it for months, what already happened 2-3 times :) I plan to release the source too, but i'm still not sure of which license to use.
So feel free to play with these and contribute any idea you have to improve these toys :p
By the way, if i am nt bored before, my next toy should be a spell explorer...
