Josh Bassett @nullobject has been hard at work, and is bringing another title to his Cave core, this time it is Donpachi

Josh will release a beta for testing once he has the sound working, if you wish to help with testing sign up to his Patreon here:

This is one of my favorite arcade games! I’m excited to see nullobject resurrect this forgotten classic.

Great game and good work!

I'm noticing some audio oddities with the volume cycling up and down a bit, almost like sidechain ducking at times. Also some odd spikey transients on some sample, perhaps when multiple samples are triggered nearly simultaneously. The latter also sounds like exaggerated sidechain ducking with a fast attack constant.

When I compare it to DonPachi on my Tiny Arcade machine the audio seems a bit more erratic in the MiSTer version. Maybe this is exactly how the game was designed and it's simply easier to notice these oddities now.

I haven't played the original arcade so my only reference is my other machine with DonPachi and my general audio experience as an engineer.

Noticed that shift in volume too. Completely unaware how that behaves on a real pcb.
