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?
If memory serves that would be in the bios/mame 2003-plus/samples folder to be more precise.
Thanks for the clarification
