I'm still working through how to deal with languages between thunderc and sniper. The thunderc can really only accept English and Spanish or it grows too large. The current quattrimus code simply removed other language files. But the sniper folks have requested other languages, so I need to figure out how to make those coexist.
In the meantime, I've uploaded a CM9 test ROM to see how the multi-rom thing goes. It's built from a new tree on the server, but should be pretty much the same as the old tree (hopefully). This contains the multi-rom stuff, of course, and also the conditional code for the RIL that does baseband magic for thunderc and 3G magic for sniper.
You may notice that it's a bit larger than beta2. About half of the difference is due to the multi-rom files, and half due to the inclusion of FR, IT, and DE dictionaries in LatinIME (because I haven't sorted those out yet).
This is not well tested. Have a backup handy!
