How to get lr-mame2016 (mame-libretro) working?

SpudsMcToole

@herb_fargus Finally managed to work out how to get the menu to come up and it hasn't helped. I've set all the games in the mame-libretro folder to run with lr-mame2016, but they still just dump me back to the menu.

What the log now shows is a "segmentation fault":

Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame2016/mamearcade2016_libretro.so --config /opt/retropie/configs/mame-libretro/retroarch.cfg "/home/pi/RetroPie/roms/mame-libretro/checkman.7z" --appendconfig /dev/shm/retroarch.cfg

It's the same for every ROM.

I can run most of my games with lr-fbalpha and lr-mame2003-plus. Is there any particular game that doesn't run on those two? FBA is rather recent from this year. 2003-plus is 2003 with new games supported and old games with problems getting fixes.

@darksavior Example: Cat'n'Mouse.

According to the website, the MAME emulators only support .zip files.

I would suggest unzipping some from .7z and then rezipping to a .zip. I use BandiZip, but there are plenty of free programs out there for this.

The website also warns on mame2016:
Note: This emulator is considered 'experimental' in RetroPie and has limited functionality. It requires more processing power than earlier MAME versions and will not run as many games at full speed on rPi hardware.

It will likely only run a small subset of the MAME 0.174 games.

It might be possible to add Cat'n'Mouse to mame2003-plus -- it was originally agree added in make .100

Feel free to post a new issue in the GitHub repository if you an want to explore this and if you would theoretically be willing to help test. I'm not the expert on backports, though

Already did that. I've tried numerous games in mame2016 but absolutely none even try to boot.

@spudsmctoole Have you tried looking in the log file (/dev/shm/runcommand.log) to see if there's an error hint ? Being a Libretro core, you can enable verbose logging and have a detailed run log.

SpudsMcToole

@mitu Yes, see paste above.

That's not with verbose options enabled, so it's kind of a generic error (emulator doesn't work with the ROM). Just from that log I'd say bad ROM. Run the game with verbose logging chosed in the Runcommand launch menu and then upload the log file to pastebin.com - or just look at it to sport the actual error.

That's not what the WIKI states, and it's also not correct. The default supported extension is zip, true. But 7z is supported by most of the emulators. It would be good if the config file were updated to have that added to the ones that do support 7z. You can always look at the libraries the binary is linked with to determine it. But at a minimum 2016 and truck both do. If I remember correctly, so do 2010 and 2014.

@treaves Good idea. I have at least added .7z support information to the table at the top of the RetroPie MAME docs: https://github.com/RetroPie/RetroPie-Setup/wiki/MAME
