Since there are so many clones (especially TAP) then I thought it would be a good idea to see how close they come to the original. For instance: The Definitive 070916: Master - gravity is slightly off, Death - no 500 torikan, otherwise accurate, neither mode stops after 999, also, no scoring/grading in either mode Heboris LITE 32.12: (for TAP) timings are off, Master gives grades faster than TAP Master Lockjaw 0.36 (old version, I know): contains line clear delays not present in TAP
Known limitations of Lockjaw 0.3x: No Normal No Doubles No Versus Master 0-599 uses approximate interpolated timings, not the more recently discovered stepwise timings Master 600-999 uses timings inferred from Death, not the more recently discovered separate set of timings Death does not stop at 500 or 999 Extra 1-frame delay per cleared line (e.g. 4 for a tetris) Master does not clear the playfield and turn on "Hide blocks in well" at 999 No scoring curve No ranks No white outline around masses of blocks No "breaking" animation during line clear delay Background image and music do not change
