it ɡives me an error with the messaɡe "RPG Maker 2003 RTP is not found", this actually isn't a problem for any of your other games
oh dang, I don't know why this one is doing that while others aren't. you can try downloading the RPG Maker 2003 RTP from here and see if that works https://www.rpgmakerweb.com/run-time-package
