(HP48) Looking for Dissasembler / Debugger

[Hiwi]

I am looking for a Dissasembler / Debugger for my HP48 G. ROM Version R.
I have MetaKernel 2.3 and using MASD, like it very much. I played around with some tools but they are not working or crashing the machine like RPL48.

Jazz does not work with Metakernel due do installation restrictions (Port1)

A debugger is not in the first place of my wishlst but a memory browser or dissasembler for entry points would be nice.
Any recommendations?
