to implement a DIVMMC instead of ZXMMC. The resulting setup runs msxdos just nicely:

The board being used is the MiST board and the modified source code is available at:

Thanks for the great esxdos.

I have just once tiny feature request: Can you make the NMI menu usable via a kempston joystick? I mapped the NMI button to the fourth fire button of the USB gamepads i use. If the menu itself would also be joystick usable then the whole setup could be used with nothing but the joystick.
