I honestly don't know how I did it. I've gotten 6.07, two 6.01s, and countless other variations. I just used a emulator until I ordered a 2600 that has been modded for composite and today was an excellent day. I don't know if it's cheating that I:
A. Use a new retro-bit controller,
B. Use it upside-down (thanks, cerebral palsy!) But, I don't know how I can improve the score. Perhaps I can hit a 5.57...
