A unique and fun experience
For MovieCart Atari 2600
The MovieCart is a very unique cartridge for the Atari 2600. There is something comforting about watching a video from your Atari. With the lights down low, the MovieCart's resolution, and a certain amount of suspension of disbelief it is possible to feel transported back in time.
In addition to the board itself, there is a wealth of support. The Github repository holds documentation, how-to videos, patches, and the code itself. The developer "MovieCart Stuff" is also very responsive and supportive if you need to reach out. There is also an open discussion on this topic at AtariAge.
That being said, the cartridge does require some effort on the purchaser's part. All videos will need to be converted to a new format. The how-to videos and documentation make this fairly painless. Also I recommend any purchaser to protect the board either in an old game case or 3D print a new one. The board can be damaged if not properly protected. Also anyone attempting to apply a patch should read through the process very carefully and make sure you have a good patch file. Not all patches can be rolled back.
Overall the MovieCart has been worth the effort. It is not only fun, but I am learning from it as well. And any day you can learn something new is a good day.
