Trouble running ADAM roms on lr-mess

[theburgerking]

I have the TOSEC ADAM rom set and I am extremely excited to play some of these games but very very few run for me. The ones that fail all fail with the same error (see the last line of this log clip:

[libretro INFO] Starting game from command line:adam -rp /home/pi/RetroPie/BIOS -cfg_directory /opt/retropie/configs/adam "-flop1" "/home/pi/RetroPie/roms/adam/Super Zaxxon (1984)(Sega - Coleco).zip"

I've tried specifying both the zip and the dsk file within with the same results.

I have also had success with some of the roms included in the set, which helped me validate my approach and bios files and locations.

My lr-mess was installed from source 2 days ago so should be considered current.

Any ADAM experts out there have debugging steps for me? Thanks in advance.
