Saturn USB Mod

Something curious is that the address space appears to be used to configure the behavior of CS2. It is even possible to configure wait cycles, which could be useful for increasing transfer speeds.

so I got the 4MB cart working with the CS2 address lines and just grounding data pins. Just need to get the circuity to work.

Another question I have been asking myself is why not just place the FLAGs on the higher part of the data bus? Then I can eliminate the octal bus all together

Nevermind, the reason why I need the octal bus is because there is no other way to stop RXF and TXE from outputting on the dataline.
