You don't have to list it in the app store. Last time I looked (which was, admittedly years ago) TIC80 would violate the terms for the App Store anyway due to carts being downloaded and using a scripting language.
I think it would be easier to have a cart export for something like Cordova (especially since html export is already supported), which could be used to target iOS, but I don't have very much experience with that.
