Humble Bazooka has just released an adapter that converts the output of an Atari Jaguar to a Genesis 2-syle MiniDIN. That means ALL Genesis 2 cables should work with the Jaguar – Everything from composite, to RGB SCART, to HD Retrovision. The price is $35 plus shipping, however if you’d like a fully-featured version, with multiple outputs and a JagNet adapter, check out the other options from HB in the main Jaguar page linked below:
I’m really glad there’s now so many choices for the Jaguar! It’s my personal opinion that spending a bit more and getting every analog output might be the best option for most people, but that’s 100% up to you! What if you have a nice scaler like the RetroTINK 5x and an all-RGB setup through a switch? Then those extra outputs would be totally useless to you. And what if you have a setup like that, but also have an extra Genesis 2 RGB cable lying around? Than this adapter is perfect.
Really, just step back, think about your setup for a moment and choose the best option for you. There’s honestly no “wrong” answer, just whichever might be better for you.
