Bigger jumpholes

Not sure if this’ll work but JH are objects in systems so they have an associated model (3DB), look in SOLAR/DOCKABLE for jumo_hole and have a look using HardCmp.
You could try FLModel Tool and see if’ it’s able to scale up the model to the size you want or use Milkshape to create a larger version.
Other than that you may need to edit the jumphole effect ALE file and about that I haven’t a clue
