Here's a special bonus: a small CHD (830KB) that runs perfectly on the MESS Saturn driver (use SVN #2600 or later to fix a regression that struck in 0.124u4). It's also a previously unreleased "rarity" - the QSound Inc official demo for the Saturn made by game audio legend Brian Schmidt. Our current Saturn audio emulation happens to finally be good enough to reproduce it as it's meant to run, so it seemed like a good idea to put it out and about.http://rbelmont.mameworld.info/qsound.chd
(copy/paste the URL if necessary).
On commandline MESS, that's mess saturn -cdrom qsound.chd
then follow the demo's on-screen instructions.
