// The original minimig had the keyboard connected to the FPGA. Thus all key events (even for OSD)
// came from the FPGA core. The MIST has the keyboard attached to the arm controller. To be compatible
// with the minimig core all keys (incl. OSD!) are forwarded to the FPGA and the OSD keys are returned.
// These keys are tagged with the "OSD" flag
// The atari/mist core does not forwards keys through the FPGA but queues them inside the arm controller.
// These keys are tagged with the "OSD_LOC" flag. The keycodes itself used are identical between OSD
// and OSD_LOC
