First, a reality check. No physical NES cartridge ever contained 99,999 unique games. The NES (Nintendo Entertainment System) has a known library of approximately 1,300 officially licensed titles globally, plus a few hundred unlicensed and homebrew games. To reach 99,999, you would need to include thousands of duplicates, hacked ROMs, corrupted files, and "filler" programs.
