I just changed from MinUI to OnionOS on my Miyoo Mini+ to try more forms of emulation such as Arcade. I specifically want to play Bosconian. I got it running via the core “MAME 2003-Plus” using two different ROMsets, “bosco” and “boscomd” from the Archive.org “MAME 2003-Plus Reference Full Non-Merged ROMsets” page.

However, I’m having the same issue with both being “Warning: audo sample(s) not found”.

Did I happen to pick two bad ROMsets or is there some larger issue I’m having? Is this a common issue that people know how to fix?
