Upstream will probably take some time to fix the build problem, but we should have a workaround in RetroPie-Setup for it. Just update RetroPie-Setup and the installation of the core should work.

Update your Retropie-Setup script and then reinstall the PC98 core and restart EmulationStation - after this the .fdd extension should be recognized by EmulationStation automatically.

@mitu Anything I can help with or you want me to check test feel free always to ask

@mitu Yeah, I am sorry... I did something that required it, and then neglected to change it back. Poor form.

@TPR

Did it work ?

@folly Nice!

@phineascage I have a similar problem. What did you do to get the controller input to work?

Added Atari 800, SNES, and Super Famicom.
