240p Test Mini is a size-optimized port of Artemio's 240p Test Suite to 8-bit consoles, with supports for:

  • Nintendo Entertainment System.
  • Game Boy and Game Boy Color (as "144p Test Suite").
  • Game Boy Advance (as "160p Test Suite").

Some functionality has been rearranged to fit the controller or to combine the function of similar tests. Some help pages have been rewritten for completeness, conciseness, and English usage improvements. Some tests' graphics have been replaced to keep the software free.
