International Superstar Soccer 2000 (officially abbreviated as ISS 2000 and known as Jikkyo J-League 1999: Perfect Striker 2 for the Nintendo 64 and as World Soccer GB 2000 for the Game Boy Color in Japan) is the second game in the Nintendo 64Perfect Striker series and the last in Konami's Jikkyo Soccer series of N64 games developed by Konami Computer Entertainment Osaka. For the North American and European release in 2000 the rosters were updated. It was the first and only game in the series to support the high resolution mode through an expansion pack, however this mode achieved abysmal performance, making the game virtually unplayable.
International Superstar Soccer 2000 features one of the most comprehensive team rosters in football video games, with exactly 100 teams in total. Particularly, every nation affiliated to UEFA at the time is present, since one of the game modes consists of a European Championship on the same format as the UEFA Euro (which had an edition that year), including the qualifying round.
