--superseded, see later videos-- WIP of level 4. I think the first half is pretty good, but the second half needs some work. I lose quite a bit of time in the first block section. But, I gain quite a bit in the second block section with better star RNG which I got by killing the last enemy in the previous room. Unfortunately I can't seem to get a good boss fight. Right now I'm losing about 30 frames because the boss is having a longer delay between actions. Pretty frustrating. If I can save some time in the first block section though and keep the good second block section I should be comfortably ahead going into the last level, still needs some work. At least everything works on console so far.

Looking great so far! I'm pretty unclear on what the benefit of getting the leaf is at 5:37. It doesn't seem like it makes you move faster. Is it the only way to destroy those blocks, and are you able to un-puff and run like normal? And also, does the boss not drop a 3rd bomb if you don't get to the first one fast enough?

The grayscale palette will do just fine.

Link to video Double lasers confirmed possible on Kracko! I got this by pure dumb luck. No idea what conditions are needed to make it happen. It seems like it happened after delaying the first hit by a couple frames but it could just be a coincidence. In any event this is a pretty big time save. I still need to optimize the second half of the fight, but this should be ~1 second saved. movie file: https://tasvideos.org/UserFiles/Info/638046721579096766

You cannot un-puff with the leaf. I actually tested not getting the leaf. It is possible to use the quick action trick and get by the blocks slightly faster, but it is slower traversing the next section without the leaf, because maneuverability is so much higher with the leaf. I'm pretty sure the boss will always drop 3 bombs.

I like the default better than grayscale.

Alright. I was thinking it looks almost possible to absorb and fire all 3 bombs without having to take damage (allowing for more damage boosts).

I believe this is only possible with the quick action trick. To set up the trick for the first set of bombs requires swallowing an enemy in the previous room, which would cost more time the any potential damage boost would save. With double lasers this is not applicable for the second set of bombs, so it seems like using both damage boosts on Kracko is the way to go. EDIT: Actually looks like it is possible to do quick action with second set of bombs even with double lasers, but I seem to get a faster fight with the damage boost. I went back and retimed both block sections compared to the original run and they come out about the same somehow, not sure how this is possible, but whatever. Timing Kracko I do save about 30 frames over the original run, so that is good. I'll try to optimize a bit more and save see if I can save any more frames, but it seems like it's almost time to move onto level 5.

World 1 Room 3 improvement (9 frames faster) https://tasvideos.org/UserFiles/Info/638356675385292542 World 4 Room 5 improvement (39 frames faster) https://tasvideos.org/UserFiles/Info/638356742970915222 Game version: Japan v1.1 Both Bizhawk 2.7 and 2.8 should work. Skipping spicy food in World 4 Room 6 looks to be about 200 frames slower than using it.

I found a difference between J1.0 and J1.1. The game produces a little star sprite when Kirby lands on the ground or bumps into a wall. J1.0 will always produce this star when Kirby lands or bumps into a wall. But J1.1 added a condition so that only one star can exist at a time. Lololo miniboss can create a little star sprite sometimes (I'm playing on Hard mode), so while his star sprite is on the screen, Kirby will not create one. J1.1 added 5 bytes of code at $37B1 "FA 14 D4 A7 C0". The game checks $D414. If it is 0x00, the game will create the star, else it won't. This is also the reason why the current TAS desyncs at Stage 2, because Kirby creates a star sprite in Lololo miniboss on J1.0 whereas J1.1 doesn't, while playing back the movie file on Bizhawk 2.8. Knowing this, it may be favorable to use J1.0 in TAS because you will have more opportunites to advance the RNG.

Dedede won't try to inhale you if he is at 1 HP, to prevent a graphical bug with him inhaling you while he gets killed.

I figured out the whole story now. You can read about it here: https://tcrf.net/Kirby%27s_Dream_Land#Revisional_Differences J1.1 is basicly a bugfix for a game-breaking bug that could happen in the Whispy Woods fight. That being said, I don't think this is any useful for speedrunning, but still interesting nonetheless.

Cool! In the oddities section on that page, I see you uploaded the images for the normal and extra game end screens, but I don't see a difference, did you mean to upload a different image for one of them?

The tile in the center of the image is replaced by a white square tile.

Hi there, I'm a speedrunner of this game and I'd like to help improve the TAS. The problem is that I have no experience TASing, but I'm good at finding new strats and manipulating RNG. I've been struggling with saving every frame possible and haven't been able to sync up my improvements with the current TAS, so I was wondering if anyone would be willing to help with the optimization or teach me how to make the game not desync after changing one thing. As an example of what I'm good/bad at, I changed the ending of the TAS, starting right after Kaboola 2 is defeated, and got it to be sub-9 minutes: https://tasvideos.org/UserFiles/Info/638466906468908702 There can definitely be more frames saved in what I have there.

Hi! If you want you should jump in the Discord linked in the "Chat" section of the site here: https://tasvideos.org/LiveChat There's some specifics to GB stuff especially one's like Kirby's Dreamland that we've already verified that I can get into more detail on in a chat environment.
