Now with less Puppy Loves and even faster rounds!

Could you post time per level comparisons?

Preliminary script. No idea if it will be any useful, but it shows some stuff. REMOVED, SEE BELOW 7a - end of batch 64 - psycrow goes up 63 - psycrow goes down 30, 31 - puppy 03 - randomly jump forward 0e (followed by 08) - randomly jump back 62 - bomb As we can see, it goes back and forth through the config table, using rng for jump offset. There's a fixed number of bombs in the table, so it should be possible to manipulate it to load config address closest to the bomb. Will dump bomb addresses later. Puppy speed that affects the amount of bounces they will take can be (and is) predicted, but I'll look into how it can be affected by randomness, if possible. In any case, if we know what outcome we want to get out of manipulation, it should become easier to succeed and improve.

Could you post time per level comparisons?

Added time table for time comparisons. I notice now, that I lost small time on three stages, but I'm kinda burned out from TAS'ing. I'll go back at a later date and re-do this run. I'll check the script you made and see if it can help out further for later

Finally, an Earthworm Jim 2 TAS. Well done as well, I was quite entertained. Voted yes.

It shows who calls RNG routine and how man times per frame. It tells you when is the next bomb/jump back/jump forward in config table, how many waves and steps are left. It shows the address it jumped from, which it will return to later on, and how long was the last jump, and what direction is was in. So you can apply your manipulation and see how far forward it allowed you to get in the table, which means, how many waves you skipped. Didn't investigate 100% of cases what calls RNG roll, but it's no hard to do, once needed. All in all, you guys can now know what the game is doing. I was going to try this manipulation myself once I finish, but it looks so tedious that I may prefer to delay it until the new version is done.

Much more better in my opinion: https://gist.github.com/realmonster/83a7b48c3ad0abd1d17c Warning, script for gens! Also, there is human readable dumps of scripts. All that is random based is rndcall. "Randoms left:" counter shows how many calls to rndcall left. Middle section - main script. Right section subscript, that was called from main script by rndcall. Main script terminated by command stop, but subscript termnated by command ret, and continuing execution in main script. More about commands: save - stores line in script where you restore if you die. text - shows text on screen. inc - increasing timer marked on screen "Timeout:" dec - decreasing timer marked on screen "Timeout:" def - sets value to "Timeout:" p0 p1 p2 - position where next puppy/bonus/bomb will drop puppy, bonus, bomb - drop appropriate thing. Bonus replaced by puppy if "Bonus: no" shown by script clr - makes "Bonus: yes" down - Psycrow moves down up - Psycrow moves up upp - Psycrow moves up but in some different way (idk) smt - set max of "Something:" incs - increase "Something:" idk - interesting thing, it changes chance that throwed bomb by Peter will deflect Psycrow house, and start falling on ground, so you will need to bounce it :D Zero value means never deflect. It set to non zero only in Puppy Love part 3 table - sets table of possible subscripts for rndcall diff jmp - if difficulty equal to first operand, it will jump on address set by second operand. Easy = 0, Normal = 1, Difficult = 2 round jmp - if round < value of first operand, it will jump on address set by second operand end - waiting when all puppies/bonuses are lost/done, so actually end command is awaiting end of wave. wait - like "no operation" but "-" in front of it means that it will wait unitl "Timeout:" reach zero. All commands where "-" in front of it, means that it is waiting when "Timeout:" reach zero. Suffix "x5" means that command is repeated in script 5 times in row. Tables in the end of dump - subscripts chosen by rndcall. For each round there are several of them, appropriate chosen by RNG. Didn't test waves, steps thing made by feos, because I simply don't understand them. Maybe I'm too stupid... Also "next bounces" works kinda awkward to me. You can say about next position by looking for next p0/p1/p2 in script. All timing thing based on timer shown as "Timeout:" Beware, some code increasing current value of it by 1, or even for big values. For example text command increasing current timeout often that current exceeds max (default). This script showing only script behavior. It would be nice if someone would also made investigation about timings in frames of all that stuff. I don't wanna do that, also, I guess it's very hard. -_-

Thanks guys for the lua scripts, I'll put them to good use when I do more testing

Is this testing going to happen in the near future (so you'll cancel/update this run) or some time later (so I should judge this run now)?

Testing is not going to happen for a while. I'll do more testing after the new year when I have more free time. So please, go ahead and judge this run

Regarding improvement, it would look like this: manipulate rng, and make the game branch only to the shortest subscripts. Thankfully there's only a few of them for each round, so all can be tested for how long they last. But in-level possibilities for this manipulation are limited by the amount of puppies one can drop and by places to drop them at. Additionally, rng can be rolled in a previous level during the boss fight and so, making it even more tedious to manipulate far away events. So I'd say it should be left for the new version of this run, and this one just accepted. And then, I'm going to publish it.
