Sorry for bumping this, but there are json files for the rides that you can edit to add +127 excitement, intensity, and/or nausea, but that is all I know about modifying the core without much coding knowledge. Heck, you can make them never crash/collide or even never have breakdowns or even have them all sheltered by modifying the jsons. Just to be aware, it does require a lot of patience to go through all of those jsons to find what you want. My suggestion for editing them: Use notepadd++ as the integrated one, at least on windows, is terrible. Also take note that they will be updated once in a while, so expect the need to re-edit them.
