I really love this idea, but I have questions. I own a Duo, which doesn't have that expansion port, so would this include a cable that would allow me to use this?
Also, will this box cause any input delay while playing? I had a bad experience where I tried a SCART-to-HDMI box that caused input delay depending on the system.
And by the way, the Genesis 2 and 32X have a different video connector from the Genesis 1 and Master System. Have you considered that?
If this box will work without any issues on my Duo-RX, Sega Master System, Sega Genesis (with Sega CD and 32X), and SNES, without lag, I would most likely buy one.
