With GTA, SCUMMVM, SNES, ToE, DGEN, etc. my playbook is pretty booked up for the next 3 or 4 months. I can wait on a quality BoFIII translation.
About zinc, you're right, they haven't released the source.
But imagine being able to play the list of games found on the following link:

Playing the actual ARCADE VERSIONS of the games themselves would be nice. Like MAME, only for newer games. I run it on my PC and it's damn fast and looks excellent.
Now, the M1 Modeler emulator for a different set of Sega Arcade systems and the games that run on them will have its source code released (comment on their forum dated 25 OCT 05) as soon as version 0.8, so that could be looked at.
You could always email the zinc author and see if he would be kind enough to give you the source to try your hand at a port.
