@mitu
tank you...
now , I can play Vigilante 8 with reicast oss.

I am going to answer this one myself in case anyone else needs this info in the future. After looking through the run_mess.sh script itself, I was able to see that the message "hn613128pc64.bin NOT FOUND (tried in pv2000)" was trying to tell me that lr-mess was looking for the BIOS file in a pv2000 subdirectory of the main BIOS directory. Once it was placed there the logic to skip the software list/hash started working properly and I was able to launch roms that did not match the official hashes.

Case sensitivity INSIDE another file has gotten me multiple times.

Hmmm im getting to a point that i think Reinstalling retropie will maybe help
what do you think about reinstalling ?
