Well, I'm finished. My product is a completely generic BaseConverter that works in either direction for base 2 through base 36.

KixGolf score = 591
code:
Function BaseConverter($value,$frombase,$tobase)
...
Endfunction

Time to solve the stated problem: 40 ticks
Time to resolve the inverse: 10 ticks

I am going to see if I can tighten up the code a little tomorrow.
