I wish to request MAME DEVs to add a SHARP x68000 MIDI expansion device to the HW list being emulated by MAME. I check the source code in MAME for x68000 and found that it does list up the expansion port but I do not think we have implemented any expansion board in MAME. I can buy the old hardware and send it to a MAME DEV personnel so that they can implement it.
Please let me know in case this is the wrong way to ask
