I spent a while being confused at your statements until I realized you were talking about putting a real 32X base on the RetroN5. Dang, I'm slow!

What I was wondering though would be how difficult it would be to simply emulate the 32x using the RetroN5's current specs. The base cart connector would be the same as Gen/MD, so I would presume at least on the side of physical connections one wouldn't need the 32x itself or any kind of passthrough. I would assume that difficulty in emulating the 32x would depend on how they handle the emulation of Genesis itself (IE. if it's as hardware-accurate as something like higan, than 32x is unlikely.).

I was mostly curious about this because the 32x is the one platform they could probably add support for that wouldn't require changing the physical console spec (IE amount of cartridge slots or shape) in any substantial manner.
