I've got an adaptor for foreign games, but it doesn't work for games out later than Banjo-Kazooie, so I've got to buy an other adaptor... I've seen Universal Games Adaptor v4 and Passport III, but which is the best of these?
Best choice: Bulk N64 Console - Your Power Supply Unit works fine with it, no need to change it. 100% compatibility with all games. +- 25€ / $ for Bulk unit.
Second choice: Blaze v4 - Very good compatibility - Expensive +- 60 € / $
I had a Passport III, it was alright until it just stopped working. Apparantly i'm not the only who had that, so i'd say it's not reliable.
I use the Universal Games Adaptor v4 ever since and i must say i'm quite pleased with it. I haven't encountered any problems and it's relativily cheap (i believe it's somewhere around €25 or so).
