OK, so I was able to solve it; a couple of steps I think were necessary, the others I did as precautions.

Basically, the main issue was that my runcommand-onstart.sh and runcommand-onend.sh files were empty; these need lines to trigger xboxdrvstart.sh, which in turn should allow the GPI controls to be recognised by Mame4All. Here's what I did:

In /opt/retropie/configs/all/runcommand-onstart.sh I added the following:

#!/bin/sh

source /opt/retropie/configs/all/xboxdrvstart.sh > /dev/null 2>&1
sudo pkill -STOP mpg123 > /dev/null 2>&1
fbset -g 320 240 640 480 16

In /opt/retropie/configs/all/runcommand-onend.sh I added the following:

#!/bin/sh

source /opt/retropie/configs/all/xboxdrvend.sh > /dev/null 2>&1
sudo pkill -CONT mpg123 > /dev/null 2>&1
fbset -g 320 240 320 240 8
fbset -g 320 240 320 240 32

(the lines about mpg123 are, I think, related to background music or something like that; probably not needed, but I borrowed these from a pre-made GPI image so thought safer just to copy everything.)

Then, after a restart/reboot, I switched the GPi's D-Pad to axis mode by by pressing START+DPAD LEFT for 5 seconds, until the purple light flashed.

I deleted default.cfg in /opt/retropie/configs/mame-mame4all/cfg

Finally, I the went to GPI's 'Controls Updater Menu' and ran that script, just in case.

Just tested it and It does work in regular 2003 also.

ok cool appreciate your help.

Just managed to figure out!! I SSH'ed into the box running retropi and ran emulationstation from that console . When i did that, emulationstation appeared on TV (great). When i ran game, i saw a menu that says to press a button to configure, and there I've seen to run with verbose logging. When game exited, i opened up /dev/shm/runcommand.log file and saw that umk3-u2.bin file was missing. So I've kept on looking for 0.78 romset mk3 files until i found that there is umk3-u2.bin file in one of them ! When i found it, I've copied that one to arcade dir and ran it without issues!!!

I love mk3 ! Now all i have to do is find my notebook with special moves written on it for every character which i collected during old days ! Ahhhh, that takes me back!

Thank you, all of you for assisting ! Would not have done it without you!

I was testing the controller parsing utility of LEDSpicer when I found that was not working for that emulator on the retropie, so I used a different approach, now is working, I found out that I cannot depend on other programs functionality.

@arcadez2003 i see, thx for Info.
My Problem is that i cant stop once i have speed and the whole game becomes terrible hectic.
But maybe i just have to practice 😉

@jarhead0313 I wouldn't post multiple times about the same issue. Which MAME emulator? Seems like you have mapped the buttons incorrectly. Tell us more about the setup according to https://retropie.org.uk/forum/topic/3/read-this-first How did you configure?

@shoebox low voltage can cause big problems, underclocking is one of them. I would skip the canakit power supply as they are one of the less reliable and go straight to the official raspberry pi power supply.

I am not sure if you are still having the same issue, but I was experiencing the same thing after the latest update. I was able to fix the issue in the input settings by setting throttle, frameskip dec, and frameskip inc to ‘none’ (which can be achieved by hitting esc). For some reason when hit joystick directions I was randomly registering F## keyboard presses as well. I noticed this when binding some other controls. Not sure why, but those options above are tied to f8, f9, and f10 and seemed to be causing the problem.

I hope this helps.

Was there any resolution to this? I just got a GRS Yoke and the DEADZONE is killing any usability of this.

@pandamkii

There's a lot that you need to go over and learn when first dealing with MAME. You should start here and move forward into the docs as needed.

@m0riarty Better response might be from the better performance of the emulator tested. MAME4ALL is based on an old mame version is no longer developed, things have improved over time.
If you wish to investigate more, head on over to the docs and you can see all the available arcade emulators on RetroPie - https://retropie.org.uk/docs/Arcade/

@neo-rio said in Closing mame4all with select+start not working?:

lr-mame2000 nearly runs full speed and is blockier

Only because you choose it to be. https://retropie.org.uk/docs/Shaders-and-Smoothing/

@norbit2 said in Need Help with getting a B-Wings ROM to work in MAME4ALL:

Does anyone have a link to a B-Wing ROM that would work for me?

I think your issue is mame4all nor lr-mame2000 support B-Wings. You'll need to upgrade to lr-mame2003 for it to work.

Figured out how to do it indirectly.

In \retropie\configs\all\emulationstation\es_systems.cfg
<system>
<name>mame-mame4all</name>
<fullname>Multiple Arcade Machine Emulator</fullname>
<path>/home/pi/RetroPie/roms/mame-mame4all/roms</path>
<extension>.zip .ZIP</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 SYS mame-mame4all %ROM%</command>
<platform>arcade</platform>
<theme>mame-mame4all</theme>
</system>

In \retropie\configs\mame-mame4all\mame.cfg
rompath=/home/pi/RetroPie/roms/mame-mame4all
samplepath=/home/pi/RetroPie/roms/mame-mame4all/samples

Put all game zips in /home/pi/RetroPie/roms/mame-mame4all/
Duplicate empty zero byte zip file names under /home/pi/RetroPie/roms/mame-mame4all/roms to generate the menu in subdirs.

This also fixes issue where sample.zips shows up in emulation station menu.

After using ClrMamePro and updating my ROM set... and finding out that i didn't have to go through all of that....
i already had the correct ROM set version. All i had to do was copy over dkong.zip and then ReStart EmulationStation.
Donkey Kong showed up and played just fine after that. Thanks for all the Great Advice.!!!!!

@starfry said in Can I limit the frame rate of MAME emulation?:

here is a list of games that I've tried in MAME and found to play fast:

dkong.zip galaga.zip mrdo.zip pacman.zip invaders.zip phoenix.zip scramble.zip

we have a compatibility sheet which doesn't seem to detail any issues with these games: https://docs.google.com/spreadsheets/d/1SHspjyHavY9-PKbO2swDr52BS2Wl_mB_Vjx2Z1SXiD8/edit#gid=828747670

my only guess is that you have a keyboard or some other device that is pressing F10, which apparently toggles the throttle: see readme at https://github.com/RetroPie/mame4all-pi

@eskodisk Out of curiosity... I was looking through some of the Arcade1up forums. Apparently some of them use Mame2000 (as well as other Mame versions, RetroArch, and remnants of Retropie). Their are problems already identified that may be helpful. High-scores was one of them.

The guy who is leading the 1UP hacking charge has a thread on Reddit, but he doesn't know anything about Retropie, RetroArch, or Libreto, and was asking for help... if anyone wants to help him. ; )

@andrewlee32 Listen, MAME has made better men than you weep for their mothers! Your best bet for a good grounding is getting ROMs from the MAME 0.78 reference set, maybe you could google that... Put them in the Arcade folder and choose lr-mame2003 as the default. That is my VERY quick start guide to MAME.
