The replay requires the custom data addon AND Junio Sonic addon in order for it to load properly. (load Junio Sonic and then the save file addon for it to work)

Custom data: https://mb.srb2.org/threads/custom-gamedata-allows-you-to-create-save-files-with-addons.27064/ Junio Sonic: https://mb.srb2.org/threads/junio-sonic.28511/
