Anyways WarioLand HP is a great game and one of the most impressive technically speaking. You wrote it alone?

After some questioning I came to the conclusion that it will not be possible to implement all 255
duty cycle values as this would mean a step of 490ns per duty cycle for a 8KHz playback frequency. This cannot be achieved as saturn clock period is around 250ns (4Mhz). The number of duty cycles may therefore be compressed onto 4 bits, requiring 7,8µs per steps which is a more realistic value.

hey thank you, I was a 16 y old kid with plenty of free time at the time, this project was made almost straight from level editor to pixel arts to game engine, not the best gameplay though and also I just cant imagine it has been almost 21 years ago.. time flies.

You should port your great audio project to the HP Prime maybe didn't you ?

Sincerely,
