GameSlots - save multi games at the same time

According to @AqeeAqee ‘s github, it says this and may be why my meowbit didn’t work with GameSlots - save multi games at the same time.

F412

The F412 has a different USB module. In the board.h you will most likely want to add like this:

#define BL_F412 1

Now, my meowbit power switch isn’t working as well now, but it isn’t a big deal.
