Looks like there's a new official firmware version out, and it's got a critical bug with SNES save states - avoid this one!
Updated the tools I host to support the new firmware, complete with warnings about it. Also updated the main Github document with the first details about the firmware, more will come later when my own download of it has completed.
Updated CFW FAQ with the latest details. Corrected a detail about the relationship between arcade `.zfb` files and the `.zip` files they point to (thanks `.ericgoldstein`!). Added a note to the Firmware section about the official firmware update process wiping the microSD card, and a note to the Save States section about how to back up game saves (thanks for the suggestion @uli42! Closes#10). Added a simple firmware version checking tool, so that folks don't have to use the boot logo changer to check (which always seemed clunky to me). Added a link to `dteyn`'s silent sounds pack. Fixed some small typos.
