@shift838 said in No Movement using MAME or MAME4ALL:

The only issue I seem to be having now is even though I have 2 joystics any game with MAME if selecting 2 player all plays off the first joystick. but so far I have only tested games that had only one joystick. I still need to test games that had multiple joysticks for players to play at the same exact time.

That's completely normal if you've ever played the actual arcade games. The only time you'll have the second controller active is on games where both players play at once.

@johna4242 I had the same issue on a new setup with a Pi 3B+. I had to replace mame2000_libretro.so using an old file from another Retropie Setup from a year ago and it works OK.

Current lr-mame2000 doesn't work (segfaults).

Hello

Ok

for a reason that i don't understand, all my rom working using mame2000 emulator.

Maybe my old raspberry 1 b is not enough powerful for the mame4all emulator ...

So if it could help someone to have this info...

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.
