@mitu I've tried both .bin and .zip, the hash file for astrocde says .bin files as well as all the BIOS files zipped in the roms directory as well as being in the main BIOS directory. Still no dice.

@tobas I used the binary install on a 3b. So I know it works that way. Check the experimental install menu, I think the binary install is in there.

@rkoster Cheers, but as I said, unfortunately I'm unable to install lr-mess for reasons I don't understand.

Nobody? Not asking for any solutions, just want to know if it runs properly for anyone else...

I finally figured it out, and in case anyone needs to know for future reference:

Option 1: Go into "Slot Devices" by pressing TAB to get into the MAME config menu and choose "Joy" under "ctrl2" - This is not set by default.

Option 2: Add -ctrl2 joy to your command line in emulators.cfg - This will force a controller to put put into controller port 2. So for example, my command line for Astrocade looks like this:

lr-mess-astrocade = "/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/astrocade/retroarch.cfg astrocde /home/pi/RetroPie/BIOS -ctrl2 joy -cart %ROM%"

@teller B-Em uses the library Allegro 4.x and other libraries so I think it would need Raspbian installed.

I'll leave the astrocade to you ;)

Done and done. GitHub isn't nearly as scary as I had imagined. I hope to work my way up to a script module submission when I have some time to learn a bit more. For now, I made some small revisions to my previous Astrocade artwork to make everything read a bit more cleanly.
