Preliminary Notes

they will have version endpoint that returns a version file that just says the current version like 1002 for example and then it has .inc files per version that seem to tell you what files need to exist or not for a particular version.

note every single one of these is text files other than the patch contents itself.

So like v-100.inc will have a header that says:

# 902 1002 27033968

and a list of files and I havent discerned what this means but my guess is this set will let you update from 902 to 1002 and then it just has a bunch of lines that are like:

!78fb0446c5fee2c7116d2a238a180e8e /Y29uZmlncw==/YnVmZl9pY29uLnR4dA==
!4c8dff71d38b7ee408c41f8af06592c2 YnVmZl9zdHIudHh0
!28399910eac8b6c5f9d2c274c66ccec0 ZWxlbWVudF9jbGllbnQuY2Zn
!1a94e997ccf9ea21a25fb54d1f7bdd48 aW5zdGFuY2UudHh0

where theres an md5 of the file and a prefix that can be !,+,- and my best guess is that its a diff type thing where its like overwrite, add, remove? and then the end is a path with parts encoded as b64 to the file on the server and the path it belongs in the game.

so the first line in my example is configs/buff_icon.txt so you would download it at updateuri.com/update/${element || patcher || launcher}/Y29uZmlncw==/YnVmZl9pY29uLnR4dA== and then patcher saves it as and compress it into the configs.pck at configs/buff_icon.txt

the files are zlib compressed.
