Dependencies
SDL
|
1 |
aptitude install libsdl-console-dev (update) |
at least one libretro implementation
pkgconfig
Optional dependencies
libxml2 – For XML shaders and cheat support.
freetype – TTF font rendering
ffmpeg/libavcodec – FFmpeg recording
nvidia-cg-toolkit – Cg shaders
Some other libraries can be built support for as well, please refer to ./configure --help.
You can download either the official repository (https://github.com/Themaister/RetroArch) or my experimental repository (https://github.com/ToadKing/RetroArch-Rpi) (which at the moment is basically the same as the official one, but will have future Raspberry Pi changes before the main repository.)
I’ve tested the following emulator cores and they run at or near full speed:
- https://github.com/libretro/libretro-prboom (Doom WADs)
- https://github.com/libretro/fceu-next (NES, only tested the FCEUmm build)
- https://github.com/libretro/imame4all-libretro (Arcade)
- https://github.com/libretro/gambatte-libretro (GameBoy)
- https://github.com/ToadKing/pocketsnes-libretro (SNES)
RetroArch on the Raspberry Pi has some issues though:
- Audio uses ALSA, and due to the alpha nature of the Raspberry Pi’s ALSA driver, audio is not perfect. Expect popping and static.
i will compile the SNES lib:
|
1 2 |
git clone https://github.com/ToadKing/pocketsnes-libretro.git make |
|
1 |
the specific .so lib will be inside of the directory belongs to pocketsnes |
Building RetroArchPi
Once dependencies are installed, you can pull and install from Git:
|
1 2 3 4 5 |
git clone https://github.com/ToadKing/RetroArch-Rpi.git cd RetroArch ./configure # Script will autodetect features. Refer to --help if you want to override anything, such as --prefix. make sudo make install |
retroarch.cfg this file will be created in $HOME/.retroarch.cfg
if you got the following error:
|
1 2 3 4 5 6 |
In file included from /usr/include/libpng12/png.h:538:0, from screenshot.c:30: /usr/include/libpng12/pngconf.h:371:21: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before â.â token /usr/include/libpng12/pngconf.h:372:12: error: unknown type name â__dont__â /usr/include/libpng12/pngconf.h:372:29: error: expected â=â, â,â, â;â, âasmâ or â__attribute__â before âitâ /usr/include/libpng12/pngconf.h:372:29: error: unknown type name âitâ |
Solution: Try configuring RetroArch to not use libpng.
|
1 |
./configure --disable-libpng |
To run the retroarch emulator do it with pi user and using a interactive terminal, never with Xwindows Terminals
|
1 2 3 |
./retroarch -L path_to_core.so path_to_rom Example: |
|
1 |
./retroarch -L /usr/src/pocketsnes-libretro/libretro.so /home/pi/SuperMarco.smc |
update: fix for the problem : RetroArch [ERROR] :: Assertion failed at gfx/rpi.c:157.
split the memory 50% arm and 50% video with the raspi-config tool and will fix the problem
Thanks to toad king for his knowledge

Great Work!
Can you help me where i get SDL and the pkg config ?
Im tryin to run Openelec on my RPi with the rom collection browser..
dou you have an idea what i have to do, that i can run a emulator in that browser ?
@kevin i never used Openelec and unfortunately OpenELEC isn’t based on Ubuntu, Debian or Arch. According to the Retroarch’s Main developer in order to get the emulator up and running the first step will be install an stable distro in this case Debian. :S on the other hand of you want to have both in the same debian here the link for OPENELEC 4 DEBIAN
i hope this can help you! cheers
A good idea but i dont know if the memory split is the best solution.
Maybe a bootloader would be more efficient
But thanks anyway
Hi everyone, just to let you know I have created a automated script for the installation process, also a python console application (works, but need further dev) to help you find and run your roms. Check it out at
http://www.frost-software.com/blog/2012/7/20/super-nintendo-for-the-raspberry-pi.html
@thomascrha i saw your script and what happen if the compilation fails? it can’t take decision about it
example :
if the retroarch compilation fails because the png support ?
or if the retroarch fails to run because the share memory ?
Hello,
Everything is working as described but when I try to run it on my Rpi I have an assertion failure:
RetroArch assertion failed at gfx/rpi.c L 157
Can someone help me ?
Thanks
Yann
@yann do you have a log file for this error or more details about the error
Hello root,
I tried different .smc files (eg: Super Mario World.smc) and get the same failure:
No ROM file header found.
‘SUPER MARIOWORLD’ [checksum ok] (…)
RetroArch [ERROR] :: Assertion failed at gfx/rpi.c:157.
Any ideas ?
@yann are you using rapbian? or arch?
I am using the official Raspberry Pi Debian.
@yann ok at this moment i will compile the retroarch again using the latest raspbian whezzy out the box, let me try and i will back to you asap
Don’t know if it’s relevant but I use RCA output and not HDMI…
@yann no, i used the same conf at the very beginning without any problem let me finnish to compile and i will back to you
@yann i did my research and i found the solution to your problem
update: fix for the problem : RetroArch [ERROR] :: Assertion failed at gfx/rpi.c:157.
split the memory 50% arm and 50% video with the raspi-config tool and will fix the problem
Thanks a lot root !
In fact I changed this setting to get fuse compiling.
I will try your setting tomorrow and give you my feedback.
Thanks a lot for your help !!
Great !!
It’s running !!! Thanks for that.
The problem now is that I only see about the top left quarter of the screen…
I tried the “-f” option to get full screen, but without any effect.
Is my TV’s resolution the problem ? Is there a way to reduce display ?
@yann try to use the overlap option in the /boot/config.txt
overscan_left=20
overscan_right=20
overscan_top=20
overscan_bottom=20
This is a setting I already have. In fact my desktop looks good.
It’s only retroarch that is running with some different resolution. I also tried the settings in the .cfg file, but they don’t have any effect…
@yann i got a widescreen TV, and the retroarch appears in the middle, like a square obviously is not a widescreen game but it runs reasonably
I updated to Raspbian, and now it works !
@yann how did you update it? with
I installed the Raspbian from the RPI Download link, and built all again.
Now, everything seems OK.
I had some trouble with my gamepad, but my manual settings did it !
Thanks again for all your help.
@yann could you please share the setting for you gamepad? will be usefull for the rest of visitors
Here are my settings in retroarch.cfg:
input_player1_joypad_index = “0″
input_player1_a_btn = “1″
input_player1_b_btn = “2″
input_player1_x_btn = “0″
input_player1_y_btn = “3″
input_player1_l_btn = “h0left”
input_player1_r_btn = “h0right”
input_player1_start_btn = “9″
input_player1_select_btn = “8″
input_player1_left_axis = “-0″
input_player1_up_axis = “-1″
input_player1_right_axis = “+0″
input_player1_down_axis = “+1″
They are working if I turn off the Analog functions.
As I configured it with retroarch-joyconfig, there were some controls inversed or missing…

this is what i get when i try to run it pointing to the pocketsnes core (i used teh main git repo as the experimental one fails to compile with this as a message http://pastebin.com/75h4n88c )
any idea? as i’d like to try and get to playing some ol fashioned Earthbound on my Pi :3
@caelthunderwing try running the configure like this
./configure –disable-libpng
i used this to get it fixed http://www.frost-software.com/blog/2012/7/20/super-nintendo-for-the-raspberry-pi.html
strangely unless its in /emu/snes/games i get that %HOME/.retroarch.cfg error
but OMG X_X anyway to fix sound? i had the unforunate mistake of having headphones on when i launched earthbound X_X
@CaelThunderwing try creating a blank file in /home/pi/ with the name .retroarch.cfg don’t forget the dot at the begging
and about the script, i don’t have any against the automated version but, first need to fix some details in order to work FULLY well.
unfortunately the sound is in ALPHA state so we have to wait a little bit more to run games with a decent sound
does everygame have nasty sound and are there adjustments i could make?
sorry i dont know how to make reply edits, BUT the Alsa driver for USB Soundcard is upto the task .
just tested a generic USB Cheapie i got for 5$ off ebay, no wi have two scenarios for it,
a: my buzzing i had at first is relate dto power issue (USB Hub may of remidied this!) or.
b: the USB Extention cable i used for it is Bad. will test when i can. (i dont like using this hub for extended peroids gives me a bad vibe when i use it for the Pi. (since oddly the hub is delivering power INTO the USB Ports.)
but when on the USB Hub. i had perfect Sound! so for now i supose we nee dto use a usb device for sound till support for the pi’s own audio hardware is improved.
@CaelThunderwing thanks for your feedback i got an USB audio card here too, i will try, but when i use the HDMI sound is sounds crappy :S
[...] implementation on the Raspberry you can expect some creacking. For now, one solution for that seems to be the use of an external USB soundcard until the problems with the ALSA implementation are [...]
Hello,
When I wanted to compile the SNES liberto, it failed to find the ‘zlib.h’ as the error is :
src/port.h:67:23: error: zlib.h: No such file or directory
Any help please?
@bigbobbie need to install the zlib package in order to fix the problem
http://packages.debian.org/source/sid/zlib
remember the package need to be for arm try looking with aptitude search zlib
Thanks but it worked once I closed chromium (for some strange reason).
Now it works I have some more questions. First the image does not fit the screen (it’s way to large). Where does I configure this ?
Thanks for your replay anyway
@bigbobbie you are using RCA or HDMI ? please check this URL
http://elinux.org/RPi_config.txt#Video_mode_configuration
http://img404.imageshack.us/img404/2404/earthbboundpi.png
looks like a smaaaal cutoff on RCA out.but that buzzing i mentioned the last time? it was the one USB soundcard i had, i have one that draws a lil less power and now i have perfect audio.
Hi,
anybody else facing the problem that the time in super mario games (snes or nes) is running to fast?
@mats what you mean running to fast?
In the game there is a time going down to 0. One step every second but in the emulated game the time goes down by one every 0,5 second. This means that 10 real seconds are only 5-7 seconds in the game…

I hope people are still checking this. I just installed everything I can run a rom, but nothing I press on my keyboard works. I figure it has something to do with the .retroarch.cfg file. It’s in the same dir as the executable.
Am I missing something?
Hey I have installed RetroArch and pocketsnes on my R Pi. Trouble is, when I load up to Super Mario World the keyboard does nothing and I have not way to control the game (I’ve tried pressing every key lol) Any ideas why this may be happening? I looked at the config file and saw the key mappings, and they aren’t working. Thanks!!!
