oh, i wrote a temporary fix to make the dialog choices hack work with bitsy 7.0.
it works fine with regular bitsy, but when i tried it with bitsy 3d, i realized that when the old script tags are replaced, the patched functions are replaced too, so you still need to reapply the patches, or at least that's what i think is happening (a script tag will be executed when it's attached to the document, right? i may be wrong, i'm terrible at this)
see the screenshot - the dialog choices hack needs to alter the updateInput function (this is in the original hack, not something i added), so it replaces the tag that contains it, which in turn breaks the patched update function (and also restarts the renderer)
so if i'm right, it'd be safer to find a way to apply patches after the hacks, if i'm wrong, well, that's embarrassing, sorry about wasting your time
