Here in the UK your can buy an Atari 2600 style joystick with a load of Atari 2600 games on it ... you plug it into your TV and hey presto retro gaming! I think they cost around £25. The bit pity is that they do not have Combat on them :/
They were for sale on our outdoor market at one time, I don't need one though, I have two 2600's in my cupboard, one boxed and complete and the other is my playing machine. :lol:
To let you know there is a Atari 2600 emulator in the works. Actually 2. One done by Atari Age which is metinoed in the news section. Also another being done by GP32emu. They should be out soon.
