You have to enable hidden folders and files in kodi settings. IALR addon must point to gamestarter.sh script, not retroarch binary. Did you run IARL settings wizard?
I didn't run the wizard...it doesn't seem to start...i can sort of highlight it...but it doesn't seem to execute..the ok button works up in the box though..but that doesn't seem to trigger it ..? As far as the IARL addon is concered, it seems like it points only to a folder where retroarch is located. not a specific file in the addon settings. One other question..is it possible to upgrade retroarch binary to 1.3.4?
