Hm. Still at a loss. Do I have to save the game config to make it work? I would like to make a working configuration on the fly and only save it when it works. Also "User 1 Device Type" - I believe this should stay RetroPad? "User 1 Analog To Digital" - should I fiddle around with that? "User 1 Steering" is set to "Left Analog X" - which sounds reasonable, but does not work...

0.37b5 should provide pretty much everything for 'classic' arcade games and will easily run on the PI3 B, MAME 0.106 is the last release for the PI and this should still work ok for the vast majority of games and will still run on the PI 3B MAME version NEED a specific ROM set as each version of MAME has updates and redumps or better dumps of ROMs that were not working earlier, which is why MAME fails if you don't have the ROMs to match I do have a set of ROMs that I picked up looking for some help on how to create a custom ROM set with only working ROMs and came across the set by accident that has ONLY the working versions of each game, and the best ones of FBA or MAME. with a lot of the redundant games removed. Easy to install and comes with very simple instructions to basically copy over and its ready to go. Try searching for "wills arcade set". Thats all the help I can give Never every unzip the MAME ZIP files. FBA and MAME need the files zipped, one of the few emulators that MUST be zipped for it to work as it should There are a lot of clones and games that are non-working and some where only the clones work. This improved with later revisions of MAME but the PI can't run the later games due to sheer processing power required

@mitu @dankcushions Thanks again for the guidance. I just needed a nudge. I started 1942, got into Retrarch from there, remapped the buttons for MAME to be what essentially is A/X/L on top and B/Y/R on the bottom. This gave me the B/Y buttons the main use for the games I play most - 1942, TMNT, etc. while keeping the standard mapping for all the other systems. Thanks again!

@mitu Just stumbled over this thread because I am a proud owner of two Aimtrak lightguns since last saturday, and I'm searching for any information about their setup. :) Following the links from the video's description, I found the github page of the script in question: https://github.com/Shakz76/Eazy-Hax-RetroPie-Toolkit/ It seems like it modifies an existing Retropie installation and adds some functionality the author deemed to be useful. I didn't dive deeper into it, because I prefer to use Retropie's own tools as long as they get the job done as well. Getting my Aimtraks to work with any kind of MAME is my next goal, but at present I can't help much further.

the problem was that your foundation was wrong i think. my theory: during https://retropie.org.uk/docs/First-Installation/#configure-controllers you bound L bottom/R bottom to your L and R buttons. you should have bound L top and R top. this would probably mean that MK would have had sensible default controls (along with SF2, etc), and it would have also meant that you had no SNES button bound to the MAME menu (not that you should need access to it anyway).

in all honesty its easy to setup but you need to understand ra and it needs documented you can go back to the old way like above or set up up in controls both work im sure mark will get round to documenting it for people

@grant2258 said in History.dat in mame2003-plus?: cp /opt/retropie/libretrocores/lr-mame2003-plus/metadata/history.dat ~/RetroPie/BIOS/mame2003-plus/ Or hardlink the file to save unbelievable 6 MB disk space. :) ln /opt/retropie/libretrocores/lr-mame2003-plus/metadata/history.dat ~/RetroPie/BIOS/mame2003-plus/history.dat (I'm back from a gamer's bar and a bit drunk right now, so cut me some slack, please. :*) ) edit: Aaaand … I forgot the history.dat at the end. Corrected.

@dankcushions I tried lr-mame2003 and the l3 key is not bound there, the problem occurs with lr-mame2010 in /configs/mame-libretro/retroarch.cfg I have: input_player1_l3_btn = "nul" (bound default) in /configs/mame-libretro/MAME2010/s1945.rmp I added input_player16_l3_btn = "9" (remmaping to any another key except the l3 default, but stills mame2010 thinks l3 is the f2 key) in this example when I press "start" button on my gamepad mame bind is: 1 Player Start: Kbd P1 Start when I press "l3"(left thumb) button on my gamepad mame bind is: 2 Player Start: Kbd F2 I have set Service Menu: None. But mame stills brings service menu when I press l3 thumb button.

@vahnxdean Play it on windows with mame or buy it from steam. That game requires a newer version of Mame and I highly doubt it's playable even if you did get it running on the pi.

@amishgamer Did you watch... I watched it as a complete beginner wanting to use that DAT. It worked great for me first time.

@alistaircg which folder are you running the roms from? /roms/mame-libretro?

OK, to answer my own question, I found the problem soon after posting here (Murphy law in action). For some reason I had a file ~/.config/retroarch/config/MAME 2003/MAME 2003.cfg that was overlapping the configs. Removed it and started to work. I don't know WHAT created this file, but I will let the infromation here in case someone has the same problem.

@colebeansbroskie You should start by reading through these links. https://retropie.org.uk/forum/topic/2859/how-to-use-mame-with-retropie-help-guide/34 https://retropie.org.uk/docs/Arcade/

@ApricotRembrandt Is this happening with all MAME titles, or just certain ones. If it's the latter, which games are affect?

@stevefo I'm not sure. I've never tried it before.
