[Guide][DIY] Wine and Retropie - Legacy driver - Raspberry Pi 3B+

If you have the opportunity try first running a plain Diablo II on a Raspbian installation. it is the easiest.

--> Step by step gives hope :-)

ExarKunIv

@thepigamer i did get diablo 2 to work on Raspbian.

i did mess with it on retropie but i ended up getting a error about something missing,
i do think im missing some driver or something, ill give it another go since i know that it does in fact work

thepigamer

@exarkuniv
Is it RetroPie from PINN?
Did you succeed in setting FAKE-KMS in raspi-config and starting emulationstation afterwards?

Can you try exiting emulationstation, starting an xterm session (startx xterm) and running your "raspbian"-bound diablo 2 shell script? (with diablo 2 specific mesa drivers handy?)

You might have to start startx xterm with classic fake-kms drivers and once its started override the drivers with the ones from diablo 2...

ExarKunIv

@thepigamer so it seems that my problem was i did not install mesa correctly.
i fixed that issue
so now i got it to start.

not sure if the sound was working or not. since i have BGM and i was launching it by command line. so the music did not turn off. lol

but im getting there

@thepigamer thank you so much. I got a bit busy this week but I will give this a shot. I'll let you know how it goes

thepigamer

@exarkuniv
WTG,
Here I confirm that the legacy driver blocks ARM-diablo2 from launching in RetroPie (I tried on my 3B+ so if there was some troubleshooting I could help you but it's a nogo :-( ).

Diablo 2 mesa drivers don't start while trying to run it. So hopefully RetroPie team will release a fake-kms compliant RetroPie for older Pi's otherwise Pi 3B+ and older users will have to run Diablo 2 only from Raspbian/LXDE based distros.

There is still some way to go from having it starting from startx xterm to having a bash script which launches itself from ports section or from a custom section.

if xterm needs to be launched first (as in startx LD_LIBRARY_PATH.... wine libd2game_arm_sa.exe.so does not work) you will have to resort doing advanced scripting. this part of my guide may help you:

xterm -hold -e `cd /home/pi/RetroPie/roms/wine/installed/HOMM4_eng;WINEPREFIX=/home/pi/winex86 /home/pi/wine-pol/bin/wine ./heroes4.exe;killall xinit;exit` &
matchbox-window-manager
exit

You will have to replace the heroes 4 launching command by diablo 2 launching command.

If you need further help with that don't hesitate to answer or PM me.

ExarKunIv

@thepigamer still no sound,
i just realized that i did not mentioned how i installed it.
i used piKiss to install it all. and im on a Pi4

so i know that changes it all up.

thepigamer

@exarkuniv
Im blind from now (D2+retropie doesn't work on Pi3b+)
I have 2 tracks to try to help you:

if you are using HDMI check hdmi_group and hdmi_drive in /boot/config.txt
try to get Alsa to work in xterm :
Download a .wav sample file
Install Alsa (I think
sudo apt-get install alsa-utils
Not sure though)
Install pulseaudio (sudo apt-get install pulseaudio)
And try alsamixer command to check your sound is linked.
Then try playing your .wav file inside xterm
With paplay xxx.wav and aplay xxx.wav
If both work diablo2 will work too.

Pikiss shouldn't change anything, just make all easier.

ExarKunIv

@thepigamer ok ill give that a shot.
i did not think that Pikiss changed it, from looking at the script.

thepigamer

@exarkuniv
Oh one last thing... that might sound stupid... but make sure sound is enabled in your arm wineprefix (sound can be tested with winecfg)... :-)

ExarKunIv

@thepigamer i did see the audio tab when i was looking at the winecfg, i did try the test button. but all it did was make a little pop sound.

im thinking i have something else going on with my stuff

thepigamer

@exarkuniv
Pop sound means it works.
Which sound device shows winecfg? Alsa or pulse?
Does Diablo 2 output sound in Raspbian? it might be a problem with Diablo 2 itself.

ExarKunIv

@thepigamer in Raspbian it works and sounds great, no issues with anything

and it says winalsa.drv for winecfg, and it is set for system defaults for all outputs

thepigamer

@exarkuniv
I would focus on getting aplay and paplay to work.

That article hereafter tells you to set hdmi_drive=2 but I guess you already did it.
Tag "Sound does not work at all, or in some applications" could however help you

https://raspberrypi.stackexchange.com/questions/44/why-is-my-audio-sound-output-not-working

Hope it can help. Ive also had problems when trying to install sound from scratch... it's not easy when its not base installed :-/

ExarKunIv

@thepigamer thanks for the info, and yes for now ill work on getting aplay and paplay to work.

ExarKunIv

@thepigamer at this point i have no idea. i think its something to deal with the file that is used to launch the game. i looked at the last thing you linked and going off of what that said, my sound is working fine.

maybe someone who i has more experentce on this or even got it working, but im lost.

time for me to move on to something else.

thanks for all your help

@exarkuniv
Hello,

Maybe this can be a track for you:
https://bbs.archlinux.org/viewtopic.php?id=252174
This is an archlinux thread but such packages might exist as well in debian.

Using winetricks might help you change from alsa to pulse or vice-versa in order to try it ahead.
For some reason box86 redirects sound quite well, no idea why arm-wine has so many problems with this.
That would indeed be cool to run D2 with wine-arm from RetroPie and get a full compatibility.

ExarKunIv

@thepigamer thanks for that, i will have to take a look into it

for right now i just have raspbian with desktop installed and then retropie installed on top of that.
and i have it working good.

i might use a new card and try messing around more with what you have given me to see if there is a different way

thepigamer

@exarkuniv
might be something like
sudo apt-get install -y alsa-lib alsa-plugins libasound2-plugins

ExarKunIv

@thepigamer after some work i have come across what is causing the sound to stop working,
but so far no clue in a work around

it seems when i do a OS update the sound is killed. if i leave the OS alone and only update the EMUs and ports i still have sound.

so i when and manuly updated the OS and what not.
i have found that raspberrypi-kernel is what kills the sound for diablo2
no sure what it is changing
if i have that alone i still have sound.

so for now im leaving it
thanks for all your help on this
