What Operating System are you on? Did you install DLPortIO (mentioned at

The parallel port linker is a thorn in the side of just about anyone that owns them. There is a new USB linker being developed that ought to work with your flash cart, but it's not ready quite yet.
Oh, and when you get it all working, I'd suggest grabbing the "PD Multipac 12-12-01" that's on the same page as PocketSend. It has a whole bunch of homebrew to try all in one package.
