you missunderstood something in his post
he was uploading the game in revision r25298 including the maps of revision r25206, because nothing has changed for the maps till then
additionally he is uploading the maps as stand-alone-package of this same installer
(PS: read the whole line:
I am also including my recompilation of the maps, as of revision, R25298 (Last full recompilation as of R25206) here.
so it is the map-package of the the r25206 )
so the first is the installer AND the maps in 1 package (nearly 600 MB), the second is ONLY the maps (nearly 90MB) without any other...
if you are downloading the installer, there will be no need to download the maps again (because they are also included in the installer of same version)
update:
i'm currently redownloading the maps o i can tell you, how to use them if you still want took, re-downloaded the extra-map-package by odie
to use this in the installer-package (which still both are the same) you have to do several things:
-install the game
-look into the base-folder
-rename the 0maps.pk3 into 0maps.zip so you can extract it with archiver of your choice (7zip, winrar, whatever...)
-you're getting 2 folder:s maps and materials, delete the maps-folder and also delete the 0maps.zip file
-copy the maps-archive into your base-folder
-extract it
-done
many many many work and you don't get any advantage of it, because the maps-folder inside this extra-archive is the same as the maps-folder inside the 0maps-file by the installer !
