I am not certain if this applies to all 7800 versions, but it worked on mine. I personally did not like it, because the sound separation just made things sound “off,” as the 7800 was designed around mono sound. However if you add the pokey audio to this connection, you would have to choose either the left or right channel only for POKEY audio to retain the effect. Seriously, the best picture I’ve seen with a composite mod kit. The end result is an astonishingly clear picture on a LCD TV.

Half the work is done for you so it is easy to install and you don’t even have to modify the case. You can also connect the bottoms of R5 and R6 to different audio channels (one to left, one to right audio) for a “Fake stereo” effect. This is by far the best composite mod on the market. The initial version is a direct port with as few changes possible to make the game function on the Atari the same as the Pet. Now, I have all audio channels, and Xevious and Midnight Mutants both sound as they should. This repository is for the Pet Frogger game ported to the Atari 8-bit computers. Once I found R5 (fortunately, I desoldered it instead of cutting it out) and re-installed it, I bridged R5 and R6 at the bottom and soldered the sound wire to the bridge, instead of the indicated hole toward the bottom of the board. Then I came across the post from Tue 3:52 PM from “River Patroller” at Also, some 2600 games had no sound or distorted sound. The most obvious example was the 7800 version of Xevious.


There was a BIG improvement in image quality after I did this mod, however, I noticed that afterward, I was missing one channel of TIA sound. I would recommend a change to the audio connection:
