@finhead - which roms you wanted testing I have the whole set give me few titles and I will load them no need to upload them since I have full set
I know it sounds silly but have you tried to reinstall advancemame emulator via emulationstation binary?
It's NOT the ROMS, I have them fully working prefectly in Emulation Station. I don't need ROMS tested I was offering to load them IF Omega didn't happen to have them on hand.
What I am looking for is the paths entered in Attract Mode to run the AdvMAME emulator.
I have tried quit a few combonations but these are the 2 I tried that I thought might work but didn't.
args -L /opt/retropie/emulators/advmame/0.94.0/bin/advmame --config /opt/retropie/configs/mame-advmame/advmame-0.94.0.rc "[romfilename]"
That one didn't work as Omega pointed out Advmame is a stand alone install not a libretrocore. So I tried his suggestion which also did not work.
arg /opt/retropie/emulators/advmame/0.94.0/bin/advmame "[romfilename]"
