Astrocademo - a demo for the Bally Astrocade

[Sdw]

My first demo for this (at least around my part of the world) completely unknown console!

If you want the binary to run in MAME/MESS - or perhaps on your own Astrocade - it can be found here:

Fantastic demo!

 

Would you consider sharing the source code?

Haha! I knew if someone would do it, that would be Sdw.

Amazing! So, how was the music made?

[Sdw]

Music was composed as an XM module (with severe restrictions of course) then put through a converter I wrote to output raw data that I can then use to feed the sound registers.

I actually thought that you made the values without a converter and that you typed in the values of the frequencies into the assembly file directly, but an XM converter for the Astrocade's music processor is impressive! Maybe if you ever make another demo for the Astrocade, you could have more emphasis on the sound capabilities of this obscure system, by showing off its AM modulation, and that the volume registers exist lol (seriously, no piece of music for the system that I've heard has any notes decay, but I've heard sfx in games increasing and decreasing the volumes of the channels).
