From what I gather from Krikkz's page, aside from region, there isn't a difference in the CIC chip in one game to the next? I may be interested in a N64 ED later on and can do the soldering and such myself. If I picked up a $1.00 sport title, I can use the CIC in an ED? It'll be good to know for next time I spot one in the wild and pick it up for future use.
