Did anyone ever support RAINE/EmuDX on Retropie/Retroarch?

[JimmyFromTheBay]

One of the coolest things in arcade emulation was EmuDX, which 20-odd years ago ran super-enhanced versions of a handful of classic arcade titles with new graphics and music patched in:

It seems a tragedy that this has been lost to history. It'd seem to be ripe for adding to something like Retropie-Extra. Has anyone ever tackled RAINE?

[gomisensei]

@JimmyFromTheBay There is a pure c version of raine on it's github, that theoretically should be able to compile, but, someone with a bit more c,ompile-fu than me will have to look at it, i get an error on linking the executable.

I'll include the error context just in case someone can point me in the right direction.

/usr/bin/ld: linux-gnu-sdl2/object/sdl/sasound.o: in function `my_callback':
sasound.c:(.text+0x134c): undefined reference to `ProfileStop'
/usr/bin/ld: sasound.c:(.text+0x137c): undefined reference to `ProfileStart'
collect2: error: ld returned 1 exit status
make: *** [makefile:1498: raine] Error 1

[Lolonois]

It can be done. Anyone who wants to push this further feel free to take it from here:

I had some success with Bookworm (aarch64) and RetroPie, 32-Bit ARM should also work.

With aarch64 (rpi5), RaspiOS Bookworm (RaspiOS 12)

• install sdl2 from RetroPie setupscript
• sudo apt install nasm liblua5.4-dev libcurl4-gnutls-dev libssl-dev libpng-dev (there may be others, but the build will tell you, apt-file is your friend)
• Checkout sources from [1]
• Apply diff/patch
  • Set NO_ASM to 1
  • source/sdl/sasound.c::my_callback(): Lines with ProfileStart / ProfileEnd -> remove or disable
  • source/sdl/sasound.c::detect_soundcard(): Stripped down to SDL soundcard autodetect (may have knock-on effects, see below)
• Changes as patch:

• cp incl. folder from git repo fonts/ to /root/.raine/
• put <yourgame.zip> to /root/.raine/roms/
• Exit ES: On the console, run as root: xinit $(where xterm), then xrandr -s 640x480, then launch raine
• Config file will be in /root/.raine/configs/rainex_sdl.cfg

Known Limitations

• With SDL2.0.10 it can't be done (i.e. RaspiOS Buster based RetroPie), see: [0]
• Optimized string functions SIMD needed [2] to use properly detect_soundcard() or changes in Makefile to use standard string functions.
• No Audio / Crash when accessing sound options in Raine Menu (most likely due to short-cutted detect_soundcard() function)
• Must be run as root (did not further investigate on this)
• I guess from here it is best to ask specific questions in the Raine forum, from what I have read they are helpful, if your question is to the point
• If you run it as a project, please share your (github) fork link here

Fun fact: The question if this Emulator (it is still maintained!) always pops up after a time if it can be supported in RetroPie: here or here

[gomisensei]

@Lolonois thanks for the diff, commenting the profile lines made it compile. It crashed, so I removed the autodetect stuff, and then it worked.

It works in userland for me, not sure why you needed to use root.

No crashes around the sound menu...

my Dual Shock 4 controller is auto setup perfectly.

EmuDX works if you download the dx2 files from raine webpage, and configure the directories right in config.

[Lolonois]

@gomisensei Nice. Do you start it when a GUI (X/Wayland) is already running? That would be my guess for the differences (root/non-root) from the distance.

[gomisensei]

@Lolonois yeah, i added it to emulationstation, it works fine from there, as long as all the files are in /home/pi/.raine it works first thing, it even downloaded the roms when i started a game before i pointed it to my arcade dir.

[JimmyFromTheBay]

@gomisensei This is great news :) Hopefully someone will add it in to Retropie in a way dopes like me can understand :D

[Folly]

It took some time but I have it working too.
I had a failure at compiling first but somehow compiling worked later.
I got it working on a x64 with debian12.
That is really nice as the source-code seems to be future proof.
The roms or emudx paths can be changed in the config file :
/home/pi/.raine/config/rainex_sdl.cfg
I did not have any knowledge of the emudx files so I didn't know you need 2 files 1 for graphics and 1 for sound.
So for frogger you need :
froggerg.dx2 (graphics)
froggerm.dx2 (music)
I think that is useful information.

@JimmyFromTheBay

I created an initial base module-script with a data-folder for patching and copying the config file.
It's probably not perfect but it after many tests it worked for me.
I must admit I have used a few hackish methods.
I used my own differences files as the one from @Lolonois didn't work for me as "patch" failed to apply patches with that diff.
I also cannot make a "git diff" file like @Lolonois did, not sure how to do that yet so I created and used regular diff files.
It might be that we need to add more packages to the depends.
Also, the SDL package isn't installed by the script.
The Chance is that SDL is already installed otherwise you need to install it from the RetroPie-Setup from the dependency packages.
Not sure yet how to add SDL correctly yet.

That said it probably needs some improvements or adjustments but it's a start.

Here are the files :
https://github.com/FollyMaddy/RetroPie-raine-modulescript/tree/main

Just push the raine.sh file and the raine folder in the emulators scriptmodules folder.

Use it on your own risk.

p.s.
The paths can be viewed in the config file.

Edit:
These SDL packages are needed to compile raine :
libsdl2-dev
libsdl2-image-dev
These packages are not installed by the module-script !

@Folly sweet. I'll test it on Monday

Awesome, cheers :)

Sadly on reading the thread more closely I noticed that it needs Bookworm and I'm still on Buster and I'm not sure my Pi can handle Bookworm :(

(Whenever I try to read stuff about it to see how to/whether I can update, it's all just ARGLE WARGLE FLARGLE BARGLE and I run away sobbing.)

I think it will run on Buster as raine is old source-code.

and I'm still on Buster and I'm not sure my Pi can handle Bookworm :(

All pi's are supported :
https://www.raspberrypi.com/software/operating-systems/
But the best is to use a pi4 or pi5 and 64bit os.

Just start with a clean OS and install RetroPie manually :

Nice. Thanks for taking this further.
Positively, a few notes from a cursory look:

• The link to the License file in rp_module_licence is not right (yields HTTP 404).
• For applying the diff there exists the applyPatch function from RetroPie.
• The indent is not right in L72-74.
• IIRC chown should be changed to $__user:$__group instead of $user:$user

@Folly said in Did anyone ever support RAINE/EmuDX on Retropie/Retroarch?:

I think it will run on Buster as raine is old source-code.

It could, but it requires a more recent SDL, which would mean a manual SDL2 install which in turn will have knock-on effects on the rest of a otherwise Buster-based RetroPie installation.

Others have been down the road trying to get Raine compiled with an older SDL2: https://www.1emulation.com/forums/topic/37608-is-it-possible-to-compile-raine-on-arm-device-retropie/

Thanks, I noticed a few myself too and fixed them.

• fixed help (3th commit)
• added depends for the xgettext and msgfmt commands (5th and 6th commit) (didn't work correctly so removed in 7th to 9th commit)
• added comments (3th commit)
• lowered swap (9th commit)

• The link to the License file in rp_module_licence is not right (yields HTTP 404).

Replace with the only thing I could find :
unknown https://raw.githubusercontent.com/zelurker/raine/refs/heads/master/source/Musashi/readme.txt
Fixed in the 3th commit

• For applying the diff there exists the applyPatch function from RetroPie.

Adding applyPatch needs to be done later as it needs a proper diff file.
My earlier attempt with using applyPatch with your diff file failed.

• The indent is not right in L72-74.

Fixed in the 4th commit

• IIRC chown should be changed to $__user:$__group instead of $user:$user

Fixed in the 3th commit
