Lately I'm pretty hooked on playing ST-V games. While exploring all the functionalities in the bios, I came across this option: "ST-V multi-cartridge". After checking system16 I found out that the ST-V manual also mentions this functionality. Unfortuatly I can't find anything about how to connect multiple carts to one MB. Did it ever get supported by SEGA? Or did anyone attempt to make it work?
Also I was wondering if anyone knows the purpose of the little extra PCB bottom-right on the picture:
[ I'm asking this becouse I also have a ST-V board without this PCB, and it works 100% the same ]
