Just a nice little library I cooked up that can convert a number of base a to a number of base b where the bases can be anything you want from base 2 to base 88.
This would be useful for anyone wanting to make their own save/load code system. Which if you're doing that, you can actually very easily write the save load code to a file on their hard drive which you can then go back and copy/paste back into the game. IMO, thats a little nicer than say, just printing it to the screen and forcing them to type it manually.
