Hey fellow DKF'ers, thought some of you here might be interested in this.
In a nutshell - the circuitry that produces jumpman's running and ladder climbing sound effects had en error in it, on the first run of 2-board sets (TKG4-11). Rather than the multi-tone sound effect that is intended, TKG4-11's produce a "flat" sound effect. Mike from Mike's Arcade flushed this out, as well as figuring out the fix. I mucked through it, and hopefully the instructions are now straight forward and complete. 20-30 minutes of re-working the board, a few pieces of jumper wire, and a decent solder station is all it takes. :)
Full details are at the link below, with the complete instructions at post #16.

That sounds much better - the variable walk/climb sound has more character.
I have a TKG4-11 on my test bench and it too has the flat walk sound. I have thought about modifying the walk sound circuit to vary the sound but so far it hasn't driven me crazy enough... The monotonous sound does have some effect on my crazy level, tho. Since the modification seems not too difficult, it's worth the effort.

Yeah, I didn't really know any better til I got my red cab, and from then on it bothered me. FailFish
