lr-mess running pv-2000 cannot find BIOS file

[theburgerking]

I am using an excellent replacement RetroPie-Setup script by @valerino to explore some less common systems.

I am not able to run Casio PV-2000 roms out of the box. The system is attempting to run:

/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/pv2000/retroarch.cfg pv2000 /home/pi/RetroPie/BIOS -cart %ROM%"

This looks good, and the bios file is in place in the specified bios directory in both zipped and unzipped forms (pv2000.zip and hn613128pc64.bin). In addition another copy of each of those files is in the pv2000 roms directory alongside the actual roms.

The output I get is:
<snip>
[libretro INFO] Starting game from command line:pv2000 -rp /home/pi/RetroPie/BIOS -cfg_directory

</snip>

Note that if I launch manually like this, I can get the game up and running (but this will not work for roms that have multiple sub-entries in the hash files so is not a solution):

/opt/retropie/emulators/retroarch/bin/retroarch --verbose --config /opt/retropie/configs/pv2000/retroarch.cfg -L /opt/retropie/libretrocores/lr-mess/mess_libretro.so /home/pi/RetroPie/roms/pv2000/rocnrope.zip

I am looking through /home/pi/RetroPie-Setup/scriptmodules/run_mess.sh but do not see anything obviously off. I did get this one error higher in the run:
[.] parameters dump

Try 'dirname --help' for more information.
\t_romdir: /home/pi/RetroPie/roms/pv2000

however light debugging did not yield a solution.

Please help point me in the right direction here, I am up for trying instrumented scripts or anything else. Thanks.

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.
