Sure, ban missinghud, but then also ban the not ingame itemtracker EVERYONE uses. These are an advantage on EVERY single eden run, keeping track of transformations that would otherwise require additional mental resources, etc. This is far more impactful, and yet you are fine with it but address missinghud? And please ban everyone in racing modding their game files outside of what you can do in the option menus, removing filters, etc. Or do you want to seem completely hypocritical?

I don't think read only should be allowed. You're not running the vanilla game if you do this. How is this even a question, honestly? It's modding the game. Since when is that fair game in any speedrun ever? It doesn't matter too much on its own, sure, but that shouldn't be an argument. You can do any run you'd ever want within 3x999 cents savefiles that are easy to prepare and don't require any kind of "cheating" during the run.

Combining this with the donation overflow however is insanely strong and thus boring. I would actually stop running the game if stuff like this becomes standard. Free money instantaneously for 1 cent investment, no downside like bombing the donation machine currently has (costing time to do so). Also, if the file is read only, why would you only be able to do it once per run? shouldn't the machine be back to 999 if you reenter the shop or any other shop? But even if not, that doesn't weaken cac toaster runs considering it takes like a minute normally to get all the money, and 84 cents are completely enough on most seeds if you play somewhat smartly.

I also feel similar about the coop baby glitches, these are single player runs after all. but that's a different topic (that should also be discussed at some point though)
