Dont forget that any emulators that exist for the Amiga will also run on the Amiga core, so we'll be able to run stuff for the 68k Mac, Speccy, BBC, etc from there until native cores become available.
But with Retrode you can jack in the original game pads too.
No need for keyboard steering (although the controls is presented as an USB keyboard) or building your own interface for the FPGA Arcade. :idea:
