i forgot to say, this is a 2600 jr.
I am also going to be building a sega master system controller for it soon, using a cable from a genesis controller. Why? the master system controller doesnt have all pins wired and i want to add a reset and a select button to the controller and also dont want to deal with the matrix yet.
I changed this idea for the master system controller. I ordered a programmable remote relay kit for this so i should be able to use a remote control for power, reset, and pause. Ill let you know how it goes.
Also - i noticed that theres an issue with the video that bugs me a bit.
Newer crt tvs have more lines than when the atari 2600 came out, And i get slight borders around my picture with this kit.
If someone could point me in the right direction, for a circuit that would make the picture go fullscreen that would be great.
