Made and sent two 8.5 ROMs but not for free; the blanks run about 5 USD and the EPROM adapter was 40 USD. I charged enough to make the ROMs and the drive to the post office worth my time and recoup the cost of the adapter; i also emailed a Hex readout of the ROMs to show version numbers. Shipping was cheap.
I don't worry about copyright issues since you have to own the card to use the ROMs.
P.S., they won't fix termination issues, nor dirty card slots -- tricky little bugger.
