Apparently, both the R-4 and R-4 Pro share the same reverse polarity issue, with pin negative and sleeve positive. What do people do to reverse polarity using common Wally batteries or similar lithium ions. Do I have to hack the cable, or can this be done with some sort of Rat Shack plug?

If you have an adaptaplug, you can turn it around. Check polarity with a voltmeter.
If you've got a fixed adapter, yes, just hack the cable.
One trick I do is put a bit of red shrinkwrap on the plug if it's polarity if reversed. I have a few wallwarts that were either reversed already, or hacked by me. So I "flag" them with a red band around the plug to indicate they are for UA5, R4, etc.

Off to Rat Shack for an adaptaplug. Thanks. Steve +T

Look around somewhere here (TS) for what tips you need for the adaptaplug before you head off to ratshack. It's the exact same setup you use for a UA5, so look for posts that discuss UA5 powering with DVD batteries. This is what I use BTW, works like a charm.

Adaptaplug "M" and "B" if i remember correctly... and i bought/did this last week.
Both plugs and cable cost a total of ~$17
