Title: How does the FC/FDS switch work in a Twin Famicom ?
Post by: Pit on January 25, 2013, 02:41:44 am
I was wondering, how does that switch work in the sharp twin famicom ?

How does it enable or disable the use of FDS part ?

It will disable FDS BIOS and RAM.

Yeah I guess it just disables the internal "RAM Adapter" electrically (so it's like it's not connected) when turned into cartridge mode. When in disk mode it blocks the cartridge connector but I guess it's possible it also disables it electrically.
