Notes

  • Released alongside source code, assets, and design documents.
  • Two alternate versions exist, which are found in the 2002-02-07 B and 2002-02-07 C folders in the Codebound release, and have the file name nba.gb. From here, they will be referred to as Prototype B and Prototype C, respectively:
    • Prototype B is, in terms of coding, the same as Prototype A, but lacks uninitialized memory areas, some of which contain traces of uncompiled source code, and has a standard size of 128kB. It has a last modification date of Feb 7, 2000 13:12:42.
    • Prototype C is, aside from several differences in the header, the same as Prototype B. It has a last modification date of Feb 7, 2000 13:17:20. These differences are as follows:
