C:\Users\&USERNAME&\AppData\Local\RuneLite there will be two config.json files one says config.json and one says config_original.json. These tell Jagex launcher which script to run and it will run the config.json file. when you patch for OSBOT to open it creates a new config.json file and renames the runlite config.json file to config_original.json. All you need to do is rename config.json (with the script that opens osbot) to something like config_osbot.json. and then rename config_original.json (the script to start runelite) back to config.json. then when you press play on the jagex launcher it will open runelite not osbot, and inorder to open osbot again just do the opposite. Rename config.json (runelite script) to config_original.json, and then renmae config_osbot.json to config.json and this will open up osbot when you press play on the jagex launcher.
