Models

Models are arranged chronologically. There are no revisions.

“32X MK-84000” (1994-????)

These 32Xs have some problems with Model 2 Genesis consoles of VA3 or 4 revisions. If nothing is plugged into the side expansion slot (typically used by the Sega CD), many 32X games will refuse to work. While one could plug a Sega CD in to resolve this issue, there is also a “32X Extension Unit” available, which simply filled that side slot with nothing. These may also have a narrower cartridge slot, but this needs to be verified with measurements.


“32X MK-84000A” (????-1996)

The compatibility issues with VA3 and VA4 Model 2 Genesis consoles have been fixed with this version. To identify this, just open the cart slot and see if the PCB’s code ends with “A”. Furthermore, these may have a slightly wider cartridge slot, but this needs to be verified with measurements.
