Polish localization -> trouble :(

[Aron]

Hi all!

I want to localize tremulous and change menus, building/weapons descriptions to polish (but dont want to make any changes with
building/weapon/evos names). Everything is ok, I'm changing some of files in data*****.pk3/ui (in eg main.menu) and saving. Everything is ok, I
can see polish texts, create server etc. But when I'm trying to join into any server there is an error "invalid game folder".. The only change I have made was changing text "Play" to "Graj".. Can somebody help me?

It's because your main data pk3 does not match with the server's. You ahve to make it a modification. You cannot simply modify main.pk3 and expect it to work; in fact, you shouldn't. All modifications should be just that, mods.

so you are moding main.menu ?
no problem, extract ui folder to /base/ui and mod there, leave the pak3 file vanilla, it will work on every server
