    (or passing multiple of the same immediate value/0 to any opcode)

    Is not being able to do SEND 0,0 a bug in the assembler, or is it actually not possible?

    No, I just use the normal assembler. Anyway, I reduced the size of the program by 5 cells by avoiding immediate values. I'm not sure how much smaller it can get without doing something crazy like self modifying code.

    Hmm I meant AND + 0x1000. Anyway, manual fixed.

    Wait ... you program it with the PROP tool? ... Man you're tough.

    Hmm, right you are! It's actually CMP + 0x4000, which is a flag that tells the R1 to not store the result. Makes me wonder how many typos there are in the manual :P

    I think there's a mistake in the documentation; It says TEST is [1100 01pp psss f..g] when it seems to actually be [1101 01pp psss f..g]

    After it guesses correctly, you can press [resume] to play again.
