Won't give me option of two players on atari flashback2

The Atari has video and audio supplied by two RCA style jacks. This connection is not supported by new television technology but you can get converters for it. You should stop at a retail store and see what they have because ordering online you could get the wrong thing. Also some of them are expensive. rca to hdmi converter

It's your rf switch it's bad or not meant for that tv

It does use a slightly different controller. The joystick that comes with the Atari 5200 has 360 degrees of control while the Atari 2600 controler only give you 8 ways of motion. Teh 5200 also has a number pad and buttons for start, pause and reset.

it's a problem of your OS bit version.. install 64bit version

The Atari will not work on a HDtv, it was not designed to.

Well I think that you need the lastest updated rf switch for an atari 2600 console and plug it into either a VCR or a DVD player then for it to work on this tv type.
4 STARS if this Solution is helpful.

Is this an NTSC compatible TV? The result you describe is what can happen if you try to use an NTSC Atari on a PAL TV. The color signals are different.

Well it might be the rf switch so you should buy a new rf box for it then. If its plugged into a digital tv it won't work unless you plug it into a vcr or a dvd player.

in your system programming it gives the option for internal or external music source

There are no local repair centers in your area.If you need some console repair wesites i can give them to you but you will have to ship them your console.
Let me know
