Mapping Mouse2 from Xtension Plus controller

jlvandusen

I have tried everything. When I edit the retroarch-core-options.cfg and add the line setting the mouse to mouse2.. when trying to load centipede or any game that uses a rollerball. It doesn't see the rollerball.

NOTE: I tested the cat /dev/input/mouse2 and sure enough the rollerball sends data to the screen

I cannot get retroarch to assign the mouse2 as the main mouse for the games that need it.

Please provide more information about your system as requested in https://retropie.org.uk/forum/topic/3/read-this-first.
Did you read the Docs section about mouse/trackball/spinners ?

@jlvandusen Have you tried setting the mouse index in the RGUI (RetroArch menu) instead of editing the .cfg file ?
Start a game/rom with verbose logging enabled (select it in the Runcommand launch menu), test the trackball (and see it's not working), exit the game and then get the /dev/shm/runcommand.log file from the RetroPie sistem and upload it to pastebin.com to take a look.

Ok this has been resolved...
Appears that after wiping the SD and starting over with clean install... It now properly runs with the rollerball acting correctly and I am able to play those glorious games now.

@jlvandusen That's great ! Just for my curiosity - how did you configure the trackball - editing the config file/through the RGUI/etc. ?

@mitu - I was able to use mame4all which sees that roller correctly - very confusing how the retroarch cfg works..
Example:
To see the spinner for arkanoid I had to switch to mame4all and looking at the input shows J1 RetroPad -X and +X for the controls... I don't know how to map that here as the spinner doesn't provide anything like that in the mame config (tab) and when I edit the .cfg file I tried adding the following:
input_player1_left_axis = "-0"
input_player1_right_axis ="+0"

with no luck... still unable to get the spinner working - howbeit the trackball works out of the box with mame4all.... lol

Somebody needs to write up a config walkthrough for retroarch and that joystick system... greatly.
