Version Bytes

[Eric]

Is there any way to retrieve the current version byte from Battle.net after a patch?

[UserLoser.]

No, the only way would to be search the game's files that were extracted from the new MPQ after a new patch

You can [ugh, I hate myself for saying this] use BNLS's BNLS_REQUESTVERSIONBYTE

Actually what i have my client do is automatically increment the version byte by 1 (saved to registry).  Then it automatically downloads the MPQ - but that's pretty much useless  Then if the user adds the new game files for the patch to where they should be, and the user tries to connect to bot; if the bot gets unrecognized version, it adds 1, and does this process over and over to try and guess the version byte a few times - Good enough for me

Packet log the client and manual find it

Unless you're doing a client-side version check, why download the MPQ?  DMBot 3.0.5 auto-downloaded the MPQ's, but only because it did all the version check stuff client side...

You should check the previous version code first before incrementing, otherwise your program won't handle patches that don't change the minor version number (e.g. 1.13a -> 1.13b).  In any case, I don't much see the use for this if you aren't going to automatically run the patches.

Well for that case that was War3, where the bot uses BNLS - Otherwise, oh well.  Maybe somehow i can figure something else out

Edit:  What you said about the minor version number gave me an idea. Looking at the exe's version minor matches the version byte, but only for d2/w3 - maybe all future patches, the exe minor version will be the version byte

Best i can do without knowing how to extract the mpqs or whatever you do~

Quite a few other games have had these kinds of patches, such as Starcraft / Brood War and Diablo II / Lord of Destruction.
