How to make custom language pack for user interface?

[MVoloshin]

How can I translate RetroZilla user interface to Russian? I've heard about .xpi language packs, but I doubt that SeaMonkey translation packages will be suitable for RetroZilla.

I do not know much about language packs and how they work, but I can point you in the right direction. The SeaMonkey 1.1.19 language packs might work unmodified or with slight modification. The most likely cause for modification will be changing the version string in install.js in the xpi. You will need to unzip the xpi (7-zip will work fine for this), make your modification, and re-zip the contents back into a zip file with the extension xpi. A version string of 2.2.20190223 should work for the latest 2.2 build posted here. However, I cannot guarantee how well it will actually work. Various UI elements have been replaced/added/removed since RetroZilla was forked from SeaMonkey 1.1.19. Depending on how language packs work, some text strings may still be in English or not display at all. If you would like to read into this more, here is a link to the Mozilla localization page from around the time of SeaMonkey 1.1.19's release.

If you do make a RetroZilla-compatible language pack, please send it to me. I will find a way to make it accessible to any other Russian-speaking users that may want it.

I have installed the Spanish language package from Seamonkey 1.1.19 and then Retrozilla 2.2 has become unusable. Having to uninstall and reinstall Retrozilla.
Is there a language package in Spanish?
The Retrozilla menu "download more" leads to a link that does not work:

Same result with the de-AT language file from http://archive.mozilla.org/pub/seamonkey/releases/1.1.19/contrib-localized/
