Mapping java games in Retropie with joy2key

Elias

Hi,

I play to java games in Retropie.

I would like mapping a GamePad to a KeyBoard, I have tried use joy2key but don't work.

I have this:

emulators.cfg:

java = "/opt/retropie/configs/java/joy2key_init.sh; sudo xinit -e 'java -Xms384M -Xmx384M -jar %ROM%' -- :0"
default = "java"

joy2key_init.sh

echo "Init joy2key_init.sh" >> /dev/shm/runcommand.log

sudo pkill -f joy2key
echo "Kill possible running joy2key processes" >> /dev/shm/runcommand.log
sleep 5

readonly JOY2KEY_SCRIPTLOC="/home/pi/RetroPie-Setup/scriptmodules/helpers.sh"

# Config:
# DPAD = Cursors	(kcub1 kcuf1 kcuu1 kcud1)
# A = Space			(ASCII 32 -> HEXADECIMAL 0x20)
# B = Enter			(ASCII 10 -> HEXADECIMAL 0x0a)
# X = Escape		(ASCII 27 -> HEXADECIMAL 0x1b)
# Y = F1			(kf1)
readonly CONFIG=(kcub1 kcuf1 kcuu1 kcud1 0x20 0x0a 0x1b kf1)

if [[ -f $JOY2KEY_SCRIPTLOC ]]; then
	echo "Script $JOY2KEY_SCRIPTLOC found" >> /dev/shm/runcommand.log
	
	source "$JOY2KEY_SCRIPTLOC"
	scriptdir="/home/pi/RetroPie-Setup"
	joy2keyStart ${CONFIG[@]}
	echo "joy2key throw" >> /dev/shm/runcommand.log
else
	echo "Script $JOY2KEY_SCRIPTLOC NOT found" >> /dev/shm/runcommand.log
fi

echo "Exit joy2key_init.sh" >> /dev/shm/runcommand.log

I know that the script runs correctly, because I have threw Midnight Commander after of joy2key_init.sh and works with GamePad, but java games no.

Any idea??

Thanks

joy2key is working with the console terminal, not with X11 applications.
Also, don't use sudo to run any emulators or xinit, it's not necessary and it will cause permissions issues.

Elias

@mitu thanks a lot.

Oks, I will remove sudo.

Do you know any application to mapping keys that works with X11??

Elias

Hi,

I have read this in the Joy2key official documentation:

"joy2key monitors the joystick (normally /dev/input/js0) and sends keyboard events to an X window, terminal, or raw console. In the case of X, xwininfo(1) is used to retrive the window ID, which should not be a problem as this is a standard utility in most X11 distributions."

Then, does Joy2key must works with xinit??

mitu

@elias Which documentation are you referring to ?

Elias

Hi @mitu ,

I have tried with joy2key python script (joy2key.py) and with joy2key application (apt-get install joy2key).

The documentation where I have seen X window is the application documentation:
http://manpages.ubuntu.com/manpages/xenial/man1/joy2key.1.html

@elias said in Mapping java games in Retropie with joy2key:

http://manpages.ubuntu.com/manpages/xenial/man1/joy2key.1.html

This is a different application, same name though, than the one shipped with RetroPie.

Elias

Hi @mitu ,

Yes, I know.

First, I tried with joy2key python script (joy2key.py) shipped with RetroPie, doesn't works.

Second, I tried with joy2key application (apt-get install joy2key), neither works.

What do you advise me?

Elias

Hi,

This is my configuration to joy2key application:

emulators.cfg (like in python script ):

java = "/opt/retropie/configs/java/joy2key_init.sh; sudo xinit -e 'java -Xms384M -Xmx384M -jar %ROM%' -- :0"
default = "java"

joy2key_init.sh

echo "Init joy2key_init.sh" >> /dev/shm/runcommand.log

sudo pkill -f joy2key
echo "Kill possible running joy2key processes" >> /dev/shm/runcommand.log
sleep 5

joy2key -rcfile /opt/retropie/configs/java/joy2keyrc -config java

echo "Exit joy2key_init.sh" >> /dev/shm/runcommand.log

joy2keyrc:

COMMON
-thresh -32767 32767 -32767 32767

START java
-X
-dev /dev/input/js0
-buttons Space Escape Return
-axis Left Right Up Down

Like in python script , if I throw Midnight Commander after of joy2key_init.sh then works with GamePad, but if I throw java games no.

I'm going to try with rejoystick (http://rejoystick.sourceforge.net/)

Do we know it?
