First I'm going to provide a correction to the author's verification movie it erases Slot 1 and 2 making them accessible from the start as "Reset Memory" would delete the unlocks from the game (and in making this post I just found out there's a cheat that allows you to unlock these faster). Second. I don't think this should be branched, or well using this mode as it's just the game with a timer counting down in the bottom left running at whatever difficulty it's equivalent to. In saying that, I also have my own file which is 307 frames faster before entering the swarm of enemies fight. The author has a lot of very RTA like input going on with mashing about before the title screen (that's input being held down) and late start presses when they're needed to be sooner, basically saying there's a lot of room to be cleaned up. It's a good opener by the author, but there's a lot of room to be improved. Best of luck.

Yes, there exist lots of problems just as you said. But I'm not that experienced to perform masses of TAS operations in that game. And more significant, almost every kung-fu skill takes at least 0.5s or even more, so many of them seemed to be like RTA. I made this record to see if anyone could carry out a better or an ultimate one. I suppose the limit to the Speedrun may arrive at an approximation of 23-24min recorded in gameplay.

this is my third attempt of the game.

That being said, here's the entire Act 1 done on Director's Cut difficulty which is equivalent to Time Challenge in terms of damage dealt and taken. It's 1189 frames faster (gameplay alone) that the submission file.

And your example for this shows over 5k times of re-recording.

Could you tell me the level of speed you chose when recording, and do you use Auto-fire Input?

Anyway, have you ever played this game before? I could see that you are experienced and kinda familiar with the game.

From watching casually it seems good, but from looking at it in TAStudio it becomes clear that there are small pauses across the whole movie. In order for a movie to be published, it should feature typical TASing optimization. Specifically, each input should be done as soon as possible, without waiting.

Yes, it was just as you said. I'm merely a new comer and beginner lacking TAS recording experiences, nonetheless, my hands would have a long breath 'cause I understood when using TAS Studio it is patience & intelligence that matter. I could barely overstate my thanks & gratitude to all of you. I will take a look on that tutorial sooner and make a fourth attempt in a future time.

I've discovered that you can unlock the Director's Cut mode through an in-game cheat: on the ''select a slot'' screen, hold L and tap up, R, select, R, up, select, select. Source: https://gamefaqs.gamespot.com/gba/589599-bruce-lee-return-of-the-legend/cheats This is allowed for submissions.

There's also this page I wrote about tasing mindset https://tasvideos.org/TasingGuide/TASArt

In fact, I've known this before, but I'm not sure if it is cheating.

Cheat codes and passwords are only allowed to access harder difficulties and/or bonus content, including cosmetic improvements.
