Pi4 MAME2010 crashing on Tab menu > Inputs

pjft

@grant2258 no issues whatsoever - just sharing that note as it could be helpful:)

Best of luck with the barcade setup!

I wont be using this on a pi 3 to be honest just want to get it usable fror a pi4 if people want to use it.

Ok the updating is done there is one fix in here for the pi 4. Its a one line paragma and the rest of the updates are for the input that never worked right so it applies to all platforms. I only updated this because there might be a need for it to be usable.

There is a core option to enable auto mapping this will set selected games to automap its off by default you need to restart the core when you enable/disable this setting.

how to compile for pi4

git clone https://github.com/grant2258/mame2010-libretro.git
git checkout input
make platform=rpi4 -j8
sudo cp mame2010_libretro.so /opt/retropie/libretrocores/lr-mame2010/

you can also patch the official repo with this

wget https://github.com/grant2258/mame2010-libretro/commit/eb1d80d0625c5ecd493c9e001a5e9f3a1fd8ec18.diff
git apply eb1d80d0625c5ecd493c9e001a5e9f3a1fd8ec18.diff

@pjft let me know if you find any issues i will look out for sensible way to add the digital hats at some point!

pjft

@grant2258 Oh my, I did not get notified of these changes/edits to your post, so only now did I come back to update this.

I ended up digging into the actual issue there - thank to yours and @mitu's guidance - and came up with a smaller fix for the crash on the Pi4, on the actual struct that was causing the problems. There might be more memory leaks or wrong accesses, but at least from what I tested nothing is crashing for the moment.

https://github.com/pjft/mame2010-libretro/commit/5b689b6351b602102967dd953237fb85fbb59244

I am just running a final test on compiling from scratch and then if it works well I'll submit it upstream.

I'll test out your patch tomorrow or weekend the latest, for sure.

For the actual compilation scripts, I'd love to get other (definitely more knowledgeable) people's inputs on those -- @mitu being clearly one of them. :)

Thanks for these - they'll make the lr-mame2010 experience a lot better for 2 player games and for customizing the inputs!

grant2258

the only fix needed for the pi4 crash is #pragma i sent you. The rest of the updates is fixing the input thats badly broke and not finished

pjft

@grant2258 Correct - I ended up just narrowing it down to what was the exact struct that was being accessed incorrectly, and apply the __packed qualifier to it only, in case the repository maintainers would object to applying it to the entire file for some reason.

Thanks for putting these together!

I have one more check on the code and noticed a little boo boo the latest updates will be in the input branch if you want them it works like it should now. If you find any issues let me know. Ill check the code over in the next few days and play some games. I dont think there is any maintainers. The defaults are stored in src/emu/inpttype.h if you want to have a look at changing them. In my experience this is the hardest part to deal with there is always going to be someone that doesnt like your changes.

Ive looked at this there is two ways to do the dpad you can set it up as a button and map it in the .h file you would for digital you would need to map the dpad to all alalog controls dial,xaxis,yaxis,paddle ect. This basically means you would loose the extra buttons on the dpad because they are already mapped and you really need it for games like hard driving ect.

I think a better way of doing this would be use of a controller file if the code for that hasnt been ripped out it wil basically do the same as above but you could have a core option to enable it or not of course a restart would be required.

I'm having problems compiling or patching.
Can you help me with what i might be doing wrong.

error: Makefile: No such file or directory
error: src/emu/uimenu.c: No such file or directory

i get the above message.
Thanks

just do this

git clone https://github.com/grant2258/mame2010-libretro.git
cd mame2010-libretro
git checkout input
make platform=rpi4 -j8
sudo cp mame2010_libretro.so /opt/retropie/libretrocores/lr-mame2010/

git clone https://github.com/grant2258/mame2010-libretro.git
fatal: destination path 'mame2010-libretro' already exists and is not an empty directory.

im not sure what im doing wrong still, I tried uninstalling lr-mame2010 and still had same issue. No folder in libretrocores for lr-mame2010.
Hope you can help.
Thanks Sim

grant2258

rm -rf mame2010-libretro

then do the above

Simrose

@grant2258 said in Pi4 MAME2010 crashing on Tab menu > Inputs:

rm -f mame2010-libretro
rm: cannot remove 'mame2010-libretro': Is a directory

grant2258

its rm -rf you posted that as i was editing it. I think ill compile a binary for people probably easier that way

Simrose

cd mame2010-libretro
git checkout input

sudo cp mame2010_libretro.so /opt/retropie/libretrocores/lr-mame2010/

Thanks its installing now.

The remove command worked and used this post you made
git clone https://github.com/grant2258/mame2010-libretro.git
cd mame2010-libretro
git checkout input
make platform=rpi4 -j8
sudo cp mame2010_libretro.so /opt/retropie/libretrocores/lr-mame2010/

Im hopeing this will help with player 2 controls for some reason mortal kombat 2 etc the circle button does not do anything. Cant low kick on player 2. It will be great if it works afterwards.

Thanks
Sim

grant2258

should be good for 4 players :)

@grant2258
It was compiling but at the end it didnt install
ill have to do it again as i closed putty and show message thanks.

pi@retropie:~ $ git clone https://github.com/grant2258/mame2010-libretro
fatal: destination path 'mame2010-libretro' already exists and is not anirectory.
pi@retropie:~ $ cd mame2010-libretro

cp: cannot create regular file '/opt/retropie/libretrocores/lr-mame2010/': Not a directory

EDIT
I just had to create a lr-mame2010 directory and it worked now to test
mame2010_libretro is in the lr-mame2010 folder from your install

So I have the new core installed from you, I just need some config to launch the emulator. As before installing i removed the emulator from setup, I can see in retropie setup it says installed via unknown lr-mame2010 so i must be close in getting it working.

I think i solved it the long way around sorry im not really confident with this.

I backed up the new core you made then installed via binary
so i have the config to launch the emulator
then run just this code

git clone https://github.com/grant2258/mame2010-libretro.git
cd mame2010-libretro
git checkout input
make platform=rpi4 -j8
now its doing its installing lots of code
when that finishes ill copy over the new core over the binary one as root user
so hopefully when finished it will all be good.

grant2258

yes you need to install the mame2010 package first on thing to note if it stops compiling just go back to the mame2010-libretro
directory

the other commands before this just grabed the source and checkout the branch no need to worry about them again

make platform=rpi4 -j8
sudo cp mame2010_libretro.so /opt/retropie/libretrocores/lr-mame2010/

@grant2258
So the Controls are wrong for Mortal kombwt
Compared to arcade and mame 2003, megadrive etc
But they all can be mapped now which is wonderful
Thanks
Sim

This is how I set it now for Mortal kombat to be the same as mame 2003 and layout of how Mortal kombat games are on most platforms.

Auto 0 key z button 4
Auto 3 key a button 1
Auto 1 key x button 5
Auto 2 key S button 3
Auto 4 key q button 2
Auto 5 key w button 6
Auto 6 button 8
Auto 7 button 7

Its working really well
Thank you again

Is their a way to get dpad working and not just analog.

Thanks
Sim

grant2258

there is some mapping that was there you need to turn it on in the options and restart the core. I left them off by default because i havent tested them. So if you turn it on (then restart) and load up street fighter 2 it should map properly. Again this isint my mapping its what was there

Simrose

@grant2258
Can you please explain where options how to enable
Thanks
Sim

grant2258

@Simrose like any other retroarch core option select +x to get to rgui

then goto options

its the first option automapping turn it on close the core and restart
