I downloaded a 161 romset and used all of the updates to bring it to 175. I believe I have all of the needed BIOS files for all of the games I want to play as well, even though I think the following games don't utilize any BIOS files.

These remaining 5 files are driving me crazy. They try to run, but then immediately crash to my front end.

I solved some ROM issues with a qsound file, so I'm wondering if these maybe need a file that I'm unaware of?

Pole Position
Quantum
Spy Hunter
