At the Beginning

  1. To see if there exists any possible distinction, I compared the first 2 complete ACTs of Two different mode, Director's Cut Mode and Time Challenge Mode.
And the answer proves to be positive.
Different hitboxDifferent pixel deviation with the same enemy at the same location
Different method of enemies-attackFor instance, different movement route & motivation
Time Challenge Mode has 1 lag frame more than Director's Cut Mode, after the end of each divided ACT.
  1. Malignant Bug: If you kill an enemy from behind his back and then jump and get in contact with his "dead" body. Then he will be resurrected with 1 HP left. You will get an instant failure if in a infiltration mission.
  2. Attention: The same terrain doesn't always be the same even if they look the same.

Branch Name

  1. Time Challenge: An optional difficulty, with Time limited, based on "Director's Cut Mode".
  2. Take 0 Damage: Except for the performance and illustration of Game Story, the Player Character doesn't get injured.
  3. Speedrun: exactly as you commonly know it, rush through the game as fast as possible.

Bugs or Tricks I Used

  1. Be noticed by an enemy and then run away or get disappeared in the enemy's sight, which will urge the enemy to turn back and go aside.
  2. In addition to the item above, each sort of enemies has a different period (usually 20 frames approximately) before their finally catch sight of the Player Character.
  3. It will take several frames for Searchlight Beam to locate its snipher at the Player Character.
  4. Searchlight Beam has a pixel deviation, and so does enemies.
  5. To grab a slightly higher platform while jumping upwards, perform a Punch (B) or Kick (r). Sometimes It may cause a delay of several frames to Grab a Cliff.
  6. Most utilized solution in combat: Attack from behind the enemies.
  7. I use game embedded cheat to unlock "Time Challenge Mode".
  8. Rolling before an EXIT can save 1 or 2 frames, but be cautious to the distance from the EXIT and the Timing to perform a roll.

Optimization

  1. Falling Position Adjustment (distribution of Key (←) & Key (→) ), to reach the farthest distance when falling downwards from a higher platform.
  2. Calculate the maximum falling height, to grab the mesh, poles or ladders and then drop.
  3. Perform a punch (B) or kick (r) at former 2 or 3 frames ahead of Player Character landing on the ground, in which case, the Player's able to run through behind the enemy. But more significantly, ensure that the punch or kick touches the enemy walking ahead of you but doesn't cause damage, only showing the Health Bar (HP) of the enemy. On the contrary, should the method be taken advantage of in mission of infiltration, you will fail the mission.
  4. →→+B (Punch while running) 16 frames before dropping from a platform, and the Player will reach the farthest distance.
  5. Add or substract the number of Key (A, Jump), to shrink the period of Player being retained in the air. The less retention time of being in the air, the more frames will be saved.
  6. Velocity: running > jumping while running > moving on the mesh, a pole or a ladder.
  7. I use →→↓+B/r to give the Boss a final attack to finish him.
  8. (Stick) →→+B/r to knock away enimes and destroy the box that contains a key (🔑).
  9. I use ←+B/r in the air when confronted with an enemy that cannot be evaded in a common way.
  10. Kill more enemies at the same time as many as possible.

  5. Using Long Jump (A*7) may have a accessibility of flying over an enemy
  6. Use a Knife when jumping from an edge of a Cliff →)A +14 frames), which will lead to a maximum displacement

Finally. FRAME RULE

To be honest, I found it in the last month. But this time it's more complicated in this game so I've not got any further inspection of it. However, I did catch a point while improving the TAS in July. Each Stage (ACT, or Mission) has an exclusive Frame Rule (Overall Period). Mathematically speaking, Each patrolling route of enemies is in strong connection with a periodical function relevant to time (frame). To optimize it, is exactly to make a nonlinear programming. I don't know if I get the best optimum but it may not. If one more overall period is saved, then it'll be faster and absolutely a new record. Besides, sub-pixels are utilized to calculate speed (particularly momentary velocity), as a consequence of which a marginal difference in sub-pixels may have an great effect on displacements of Characters.

feos: Claiming for judging.
feos: Replacing with an improvement per author's request.
feos: Cleaned up the branch. Speedrun is the default goal so it doesn't need to be mentioned. And "no damage" is the canonical wording we use over here.
feos: Replacing the file with a 792 frame improvement.
feos: After watching this side-by-side with the normal mode run, I can confirm that Time Challenge Mode is not different enough from regular gameplay to warrant a separate branch, but rather it's a difficulty setting, which we don't put into branch labels.
Regarding "no damage", we only put it into branches if taking damage is faster but was avoided for entertainment purposes. If taking damage just stuns you for a while and it's optimal to avid it, this doesn't go to branch label either.
feos: Replacing with a 213 frame improvement.
feos: 52 more frames were saved (file was provided on Discord).
feos: Replacing with a file that has some more improvements (sent over Discord) and is trimmed to end input as soon as possible without getting hit by the light thing.

feos: So after all the improvements I'm finally ready to accept this run. It's much better than #7366: TrueSnokido's GBA Bruce Lee: Return of the Legend in 22:39.07 in every room (only longer in rooms where the map is harder due to different mode), better than Spike's test, doesn't have the problem Memory found in 7366S, and overall it looks really well done. The single place I had a question about can't be done quicker because you get spotted and die.
Detailed explanations about what's different in this mode can be found here.
Encoder should use this movie which shows the in-game time after the credits.

Details: Easy /Normal Each kind of Enemies except for Bosses, need, on average, 3~5 punches or kicks to kill, usually one combo of attack, sometimes 2 combos. Details: Between Director's Cut / Time Challenge and Easy / Normal 1. Strength of Enemies (HP /DEF? + , ATK +); For instance, the Player will be easier to be knocked out if he is assaulted by 2 or 3 or more enemies. Usually 1 attack will cause 1/8 of Player HP loss if not defending. 2. 2-4 Boss Battle: TWO Thugs simultaneously; 3. ACT 3 MORE guards. 4. ACT 3-1 and ACT 7-1 no Throwing Knives (Darts) for Player at the beginning; 5. More complicated Map: ACT 3-3 (Very Long); ACT 6-1 (Longer, 4 Keys); ACT 7-2; 6. ACT 9-4: 2 Bosses simultaneously but this time no other non-Boss enemies; Diao is still the last Boss to show up; 7. ACT 9-5: True Story & End, Boss: Booth. 8. ACT 6-1, 8-1 MORE Searchlights. ACT 6-1 has 3 more and ACT 8-1 has 1 more. 9. MORE Enemies in ACT 2-4 (1 MORE Thug), 3-3, 5-1, 5-2, 5-3, 6-1, 7-2. 10. ACT 9-4: 2 LESS underlings (man in a Red dobok, tied at the waist with a colored belt that indicates rank, with a Stick in his hands and long braid); 2 LESS underlings (man in a Red dobok, with bare hands and no braid); 1 MORE underling (man in a Green dobok, with Darts in his hands); 1 MORE underling (man in a Black dobok, tied at the waist with a colored belt that indicates rank, with bare hands and long braid); 2 Thugs (Bosses) Added. The total number of enemies remains unchanged. 11. Wooden Doors and Stone Piles are difficult to destroy (Costing more frames). + NOTE: The 7 features above are all the same in Director's Cut Mode or Time Challenge Mode. The enemies are easy to kill in Normal Mode, but it's even easier in Easy Mode. There are less guards in Easy Mode than those in Normal Mode.
Details: Between Time Challenge and Director's Cut 1. Of course Time Limited 2. Different Attacking Methods and Routes of Enemies (If you use my BK2 File and change it to Director's Cut Mode, you will see the same method won't work fine within Director's Cut Mode in ACT 2-3, ACT 2-4 and so on. This is hard to tell if only using your eyes for analysis.
Defense from behind the Bosses: Diao: 4 Darts to kill; Jamal: 3 Darts Thug: 2 Darts + 1 or 2 Back-aimed Kick or Punch Texas: 2 Darts + NOTICE that the Bosses usually need ONLY 1 or 2 Darts to kill if it's in Easy Mode; At most 3 Darts for each Boss I guess if it's in Normal Mode. Each kind of underlings, even the Boss-type underlings, need only 1 Dart to kill from behind, in ALL Mode. In addition, the type with long braid can be killed, using a dart, from the front. But this will never work if in Director's Cut Mode or Time Challenge Mode, and instead, Player will be given an instant failure in Stealthy ACT. Backward Punch (l + B, 16 frames cost, aimed at the Back of enemies, in other words, attacking from behind) always causes the most damage to the enemies if no Darts in possession. Most kinds of enemies can be one-hit killed using this skill, even in the Director's Cut Mode and Time Challenge Mode. Honestly speaking, any player can complete through the Easy Mode or Normal Mode easily though they are not skillful at the initial stage. But only skillful and experienced players can meet the completion of Director's Cut Mode. More accomplished players, who have a further understanding of the game mechanics, can even bring the Time Challenge Mode to an end.

Many thanks. Yes, and finally all are worth doing. I knew it could be accepted since I always spare no effort to do anything.
