The best type-in I ever typed in: Crossroads, for Commodore 64 (c64 magazine game 6502 assembly) (homeip.net | ia)

    > Every ninth hexadecimal number was a checksum byte. So you actually had to type in more like 6,700 two-character sequences, but those checksum bytes let MLX alert you if you’d made a mistake in the last eight digits.

    The crazy thing is that the checksum was a late addition to the type-in process. It used to be even harder!

      Indeed it was. Without the checksums, there was a good bet you'd make a mistake and the program wouldn't work. If you know, you know.

    This was such a great game. There was so much diversity among the enemies and they would attack each other as well as you. Non-stop action and so much going on at once, you couldn't turn your attention away from it for a second.
