Retropie 4.5 mk_arcade_joystick driver doesn't works

nicsil

Hi, i tried to install Retropie 4.5 on my GBA SP with RPi Zero, SPI display and GPIO wired with the buttons on original MB's GBA SP, only GPIO buttons are not detected as a connected controller.
All works good with Retropie 4.4 and Recalbox 6

Looks like a similar situation with the gamecon driver - the driver is not updated for recent Linux kernel versions and the compilation fails.

@nicsil I have a modified version of the driver, which should work with the new RetroPie version - will you be willing to give it a try ? It involves some command line action, but it should be fairly easy to get it running.

@mitu latest RetroPie setup downgrades kernel if updating system packages. That would be a quick fix.

@nicsil you also have the alternative @buzz offered (whilst still using RetroPie 4.5).
If you want to try my fix, then you'll need a few commands, which you can issue from the command line - exiting from Emulationstation or via SSH.

cd $HOME/RetroPie-Setup
git remote add cmitu https://github.com/cmitu/RetroPie-Setup/
git checkout --track cmitu/mk-update

# install the fixed driver
sudo ./retropie_packages.sh mkarcadejoystick

If the last command is successful, then the driver is installed - you can check with

dkms status

Make sure the driver is configured and see if it work with your GPIO setup.

To revert to the default RetroPie repository, run again

cd $HOME/RetroPie-Setup
git checkout origin/master
git remote remove cmitu

EDIT: before running the commands, check your kernel version with

uname -r

The fix applies to versions 4.15 and up, so if you have 4.14.something, then you don't need the fix.

@mitu said in Retropie 4.5 mk_arcade_joystick driver doesn't works:

git checkout --track cmitu/mk-update

this is my output:

pi@retropie:~/RetroPie-Setup $ git checkout --track cmitu/mk-update
fatal: Cannot update paths and switch to branch 'mk-update' at the same time.
Did you intend to checkout 'cmitu/mk-update' which can not be resolved as commi?

mitu

@nicsil I think I forgot one command. Run

git fetch --all

before 2nd command, the git checkout .... command.

@mitu it's ok, works good thanks

mitu

@nicsil That's great. Can you run uname -r and post the output, just to be sure what Linux Kernal version you're using ?

pi@retropie:~ $ uname -r
