Last night I bought an N64 Passport Plus from someone on eBay, as there's a bigger range on N64 games, and some that I just can't find in Australia.
While researching the Passport, I noticed that there are four revisions - N64 Passport, N64 Passport Plus, and N64 Passport Plus II and III.
Are there any differences in versions, asides from what wikipedia lists in terms of game compatibility, and the original Passport not having Gameshark?
