What are the differences between the Converters / Passports (Plus II and III)?Unlike previous versions of converters and Passports, the latest Passport Plus III plays every game on the
N64 from any region. There are no longer any exceptions of games that don't work. In exceptional cases, there were side effects such as "ghosting" (a second image appearing on the screen or a blurry image at certain times).
The newer the Passport, the better it works, the more games it supports, and the better the image quality. However, in practice, the differences are small because the list of poorly or non-working games is very small (see Nelis' submission).
