A dump of an internal Sega diagnostic cartridge for the Saturn was recently made available, so I added ROM cartridge support to the MESS driver. The cart boots but you can&#8217;t control it yet for some reason. Hopefully once it&#8217;s controllable this cartridge will lead to improvements in the emulation for both Saturn and ST-V in MAME and MESS.
