Hmmm, the idea of changing the favorites-tab was meant differently, to be honest, but I've not yet decided 100% which way to go, so suggestions are welcome... however, games in case of MESS are actually part of software-lists or device-configurations, which is completely different than in case of MAME (for 99% of all cases -- I know there are a few MAME soft-lists as well), and I don't want to implement that differently depending upon the emulator. Really, that's why there's a "favorites page" in the software-list module, and the ability to store device-configurations in the device-mapper module.
