Ah, the other advantage/disadvantage between GoMMC and HD.
 
The MMC card unplugs from the GoMMC quite easily (+), but is
often hidden inside the computer.
 
A hard drive can be fiddly to unplug, but with a BBC/Master is
often outside the case.

A Master ROM cartridge card subtly changes the signals available
on the cartridge slot, so plugging something into a catridge card
ROM socket is not identical to plugging into a motherboard ROM
socket.
 
Also, the signals actually available are subtly different to the
signals available at the ROM sockets on the motherboard.
 
I've been meaning to carefully destroy a ROM cartridge to see if I
can modify it to present the correct signals to a GoMMC. I miss my
four banks of sideways RAM :( :(
