lr-mame2014 and lr-mame not working

[Melvin.FoX]

@edmaul69 I managed to run few things on mame2014 like pacman, frogger just to see if it works. However when I tried to run this Die Hard Arcade I just got this white border as I told you and it freezed so I had to ssh reboot the RPi.

As for gcc (which is a Gnu Compiler Collection) it's a bunch of tools needed to compile (make) some binary from source. I tried it some nasty with installing it from a newer Raspberry repo but after that my whole system screwed up :/
You will have to compile it all by yourself (just Google Raspberry Pi - Install GCC 6 and compile C++14 and C++17 programs) but it takes a lot of time (from 6 to even 24 hours) and can always crash so I am not sure if it's worth an effort.

For now on I will leave Die Hard (and just install Sega Saturn port) and I will try to get back to it after some time (maybe gcc 5 will be implemented or raspberry will get a core update?). Thanks for your help guys!

saturn will perform even worse :) https://github.com/retropie/retropie-setup/wiki/saturn#emulator-lr-yabause-small_red_triangle

Some facts you'll have to accept :
Saturn / stvbios won't run at decent speed on current raspberry without a jit/dynarec, search "High Level Emulation" if you wanna learn more about that.
MAME won't add a jit/dynarec to their emulator since anything which is not "Low Level Emulation" is against their policy.
Yabause standalone have some preliminary jit/dynarec (it was added a few months ago), but as far as i know, it is far from finished. Yabause libretro currently don't have this jit/dynarec.

@Melvin.FoX yeah i cant even get the mame2014 to even try to run on anything. It just goes to a black screen and back to the gamelist.

@edmaul69 so try to do this in bash (you can try with ssh). Type this command:

/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame2014/mame2014_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%

and swap %ROM% with full path eg.:

/home/pi/RetroPie/roms/arcade/pacman.zip

Then you'll see what's going on. If there is segmentation fault as I had then it was compiled with some errors (probably compiler couldn't find or download some needed library). Paste what's going on when turning on some rom.

@Melvin.FoX i will let you know when i test it. Thank you.

/home/pi/RetroPie/roms/arcade/pacman.zip

when i type it in withe the correct info to my setup (my roms are on an external harddrive and work because i have mame2010 and mame2003 running the roms just fine) i immediately get a "segmentation fault"

@edmaul69 So it's the very same problem that I had! You have some problems with mame2014 compilation. First of all You should check your log (I know it's long... but use Find option and look for keywords like error, invalid, can't, couldn't, not etc.). You can find it in ~/RetroPie-Setup/logs/.
In my case there was a problem with connection (so it couldn't check and find necessary libraries to compile mame2014) because I made a typo in wget app config (wget is a program that downloads a file directly to your hard drive). You can edit file /etc/wgetrc and add there line withinet4_only = on. In my case that solved any further problems.
Do be careful after taking any further steps because I screwed my whole setup after some updates (do backup!).

You should do some updates:

sudo apt-get update
sudo apt-get upgrade

This will update the list of possible packages and their versions from repository and then will download and install if anything will be found.
If everything is up to date and connection to all needed repositories works than You should be able to compile mame2014 without problems.

Try steps I gave You. If it still doesn't work than You have to try set strict DNS settings. Easier will be to set it on your Internet access device (wireless or wired router). Set DNS to 8.8.8.8 or 8.8.4.4 and set that this address will be forced to all devices. If it doesn't work or You have no access than You have to set it up on your RetroPie system.

@Melvin.FoX i will do that. Thank you very much.

@edmaul69 hope it works :) Share with us what You found out.

[edmaul69]

@Melvin.FoX i will. And if i still have issues i will post them.
