Given the amount of time people spent trying to implement something interesting in Malbolge (unshackled), I would also be very interested in a detailed explanation, perhaps a blog post, of how you achieved this.

Otherwise I am inclined to believe that this must be the result of exploiting a loophole, perhaps the interpreter not implementing the malbolge specification or something.

You're free to run this with alternative Malbolge Unshackled interpreters to verify it (although you'd probably be better off using an optimised one, that fixes to some rotation width - otherwise the code will be orders of magnitude slower).
