They both fit btw. I use a model II plate on my model I sega genesis on my model II sega cd
Yeah but will a Model 2 plate fit on a Model 1 Genesis w/ Model 1 CD unit?
Nope. The Underside's Locking Tabs won't line up properly, and there are no holes under the CD's EXT Connector, so the two prongs that stick out of the Metal Plate, will hit up against plastic.
Here are the combos that'll work:
A) Model 1 Genesis + Model 1 Plate + Model 1 CD.
B) Model 2 Genesis + Model 1 Plate + Model 1 CD.
C) Model 1 Genesis + Model 2 Plate + Model 2 CD.
D) Model 2 Genesis + Model 2 Plate + Model 2 CD.
~ Notes about Combo A ~You need to remove the 4 Rubber Feet, and the one Rubber Circle, on the bottom of the Model 2 Genesis,
before attaching a Model 1 Metal Plate.
Also, there's no need to use the metal snap-on bracket for the EXT Port, on any Genesis that you connect to the Model 1 CD.
That bracket is only for when you are using the Model 2 CD.
However, the thing that snaps in to the Vent Holes, on the Underside of either Genesis, will need to be used with both CDs.
