"VS GAME" was changed to "COM-LINK" in the American release. A trademark was added to the American logo, and the copyright details were modified.
The five vowels and Y were removed for the English version; the passwords are functionally identical, just with the order of letters shuffled around (Japan's "CCBCAAEA" becomes USA's "DDCDBBGB" - see passwords). The Japanese level passwords never use letters U to Z, so nothing is lost.
The computer monitor was widened by one tile and the text crammed right up to the borders in the English version.
