Forgive me if I am getting this wrong, but is it the upgrade that is flawed (beta) or simply the inability to get your modern computers to spit out the sys-ex and load it correctly?

If the upgrade to the HarmonyM works once you manage to load it, it ain't the problem.

Problem seems to be getting a reliable sys-ex dump (which used to be a no-brainer) rather than the upgrade itself, yes?
