This system (known as 'SPI') consists of a main board and a plug-in
cartridge containing the game software. The games on SPI hardware can
be swapped by changing the top cartridge and then moving jumper JP072
to the alternative position. This re-flashes some ROMs for a few minutes
(accompanied by a techno music track). Afterwards, a message tells you to
put the jumper back to the original position and reboot the PCB. The new
game then plays.

There were a few revisions of this hardware, though most are the same with only
minor changes such as different IC revisions etc.
