If using era-appropriate hardware, I wonder if you could use archived Kubuntu repos to upgrade one at a time until it’s a modern Linux kernel.

The first thing I did when I migrated was look for foobar2000, as I knew it rivaled Winamp in compatibility. Couldn’t find a Linux client. Only Windows/Mac. Unfortunately it looks like Audio Overload went Mac only, but the legacy 2.0 version is still available for Linux so I might give that a try.

A combination of PSF/NSF/2SF/USF, various PCM streams, along with stuff like VGM, GBS and SPC.

Winamp. It’s the only audio software that supports tons of game audio formats.

I got it running in WINE, but file association has been a pain and every single time WINE launches my system locks up for a good 30 seconds.
