Sega SG-1000 & Mark III: R/F doesn't work!

You should need a manual switchbox if that's the case. Try using a Video AV Cable(yellow) with one of these:

This works in the States. Not sure about Japan.

You'd screw this into the back of your TV and then plug the video cable from the system to it like you would a manual switchbox. Except, you don't need to keep going back to switch from game to TV and you'll notice that the video quality is MUCH better! Just tune in like you would if you were using the regular switchbox.

A big advantage of owning one of these is that since it's a single part, it'll last much longer than a switchbox. I've used one of these for my game systems that needed it for a few years now and haven't had a problem. I use this with my 2600, 5200, Intellivision, and my newest acquisition: The Atari XE Game System. No problems! Joe usually gives these out at the store when buying a loose system that didn't come with a switchbox(like the 5200, which is how I got my spare).

Give it a shot and see if that works.

BTW, for the controllers, that is the case. Some games don't work with it. I had this problem with Phantasy Star with the SMS. It was very awkward using the Genesis controller with that game.

Thanks Ghost Rider. I'll look around for one of those, and eventually order one if I can't find it. I'm pretty sure a trip to Akihabara would net me one... it's just finding one there amongst the huge amounts of small electronic shops that takes so much time!

A question about it though. I'd plug that Coaxial (F-Type) to Female RCA Adapter into the TV... but what goes from the system to the adapter? Sorry if it seems like an ignorant question, but the only things I use a coaxial adapter for are my PC Engine, Famicom, NES, and I used to use one for my SNES and Genesis until I started using AV for them. I haven't touched my TI 94/A in years, but I'm pretty sure that had a switchbox. Unfortunately, it's halfway around the world from me now. In other words, most of my experience with RF switchboxes are with automatic switches.

Nice to have another confirmation about my controller ports not being broken. Thanks for that.
