There is an equipment based solution as well.

Per UT a translation program with Native ability is Complexity 5 or only 4 if one of the languages involved is an artificial construct designed for easy translation. SW's "Basic" probably counts as such.

Each language involved requires a 100 GB database so that means C-3PO would have to store c. 600,000,000 GB of data. This is not actually a problem. the storage capacity of a TL11 Personal computer is 100,000,000,000 GB. You could even do it at TL10 if you bought extra storage capacity or used a bigger computer.

The droid's brain would be a base Complexity 8 at TL11 s hit could only run 20,000 of those translation programs at the same time but I think you can probably get by with that.

You do need to assume that those 6 million translation programs are freeware but in a setting so old there's lots of time for copyright to expire. Races that don't speak Basic might hand out their own translation program the same way Adobe hands out the Acrobat Reader.

There's also the (rather cinematic) TL11 Universal Translator program but that does require a C9 computer.
