Log Message:
libretro-fbalpha: Cherry pick some patches from upstream post-0.2.97.43.

Importantly, this fixes DIP switches in quite a few games.

Unfortunately I cannot pull down fixes easily from between 0.2.97.42
and 0.2.97.43, which is a shame because there are some interesting
ones, but I can only do so much without access to the commit log.
