There are instructions on how to modify JS so that it will work with the new wrapper, in the installation guide section of the Map Mods forum
(The link is inoperative)

Credits to Maraz for the method. I just copied it, and added notes to cover the bits I went wrong on.

Good stuff, Asheshouse. I've been using JSGME for a while and was reluctant to give it up for the new wrapper system. Will try out this new method. Thanks.
