The original release of Italy 1990 had a bug where, after the World Cup final
had been played, the game would claim that the losing team won the World Cup.
The Winners Edition corrects this bug.

The version of Italy 1990 on NVG (which can be downloaded at
<ftp://ftp.nvg.ntnu.no/pub/cpc/games/sports/ita1990.zip>) features extra
graphics and animation sequences in the 128K version, and will also run on 64K
machines (albeit without the extra effects). However, this version of Italy
1990 Winners Edition, despite only running on 128K machines, does not have any
extra effects. It will also not run on Plus machines. Basically, XOR's crack
of Italy 1990 is much better than this crack of Italy 1990 Winners Edition.
