I found out I had 1.1 ... :-( so I bought 1.4 on Steam and added the sums:

https://github.com/a-detiste/game-data-packager/commit/adaccc086d595972c24ae64e3b88825416a6cda8

so now we have 2 working sets of files known for wl6 & none for wl6a.

can you also give me the size/ cksums / sha1sum / sha256sum of your alternative

 vgadict.wl6 / vgagraph.wl6 / vgahead.wl6 / vswap.wl6

Simon has added support for alternatives in the python engine
because RTCW had been localised;
so we should be able to follow this example:

[ files:
[   main/sp_pak1.pk3:
[     install: true
[     alternatives:
[     - main/sp_pak1.pk3_en
[     - main/sp_pak1.pk3_fr
