Subject: Re: Manic Miner: Format of title-screen tune
Couple of typos in my previous message, corrected below in CAPITALISED text:
"Then the duration is fed into the C register, which is then DECREMENTED 256 times by the inner loop, until it once again reaches zero to signify that it's time to move onto the next pair of notes.
The relative jump at #930D causes the inner loop to repeat if the Zero Flag is not set, and the first DECREMENTATION of C takes it from 0 to 255 without setting the Zero Flag."
Anyway, I've tested it out now and you can indeed have a note of duration 256, by selecting a value of 0 for the first of a triple of MM title-tune bytes.
