After further investigation, I think the source of the problem for the ghosted step, walk, ran was a loose connection on the filtering capacity on pins 2 and 4.  I should buy a pack of 0.1 uF and a pack of 1.0 uF capacitors and stick them in a parts bin.  Actually, what I should really do is bite the bullet and buy the PDB.  The debug seems to be a little more sensitive to power issues than simply loading and running the program.  Maybe the physical connection of the power supply or the SX-Key pins are loose on your board?  For some reason, the 7805 voltage regulator I'm using seems to need more than 6VDC input.

Anyway, my main point is that you may want to check your power.
