Triggered R_2=31. It only saves one "frame rule" over the R_2=72 movie if we cast Fairy spell. This time I took the effort to create a movie that naturally manipulates R_2=31 in.
If it took fewer frames to manipulate in R_2=31, then yes, this would be faster even with the menu loss later. There's room to manipulate away the 21-frame chunk, but not with the R_2 we had coming into the normal encounter.
RNG is complicated business to explain, really.

RAM hacked to get gTimer/RNG pair.
So Fairy spell can traverse this segment 4 frames faster than non-fairy Link. I checked for other RNG values this early, but nothing came up.
This is what happens if R_2=31 is done. If we can traverse the cave quickly enough, we will get that fairy, but I only succeed by, in this movie, casting Fairy. Assuming that magic I just spent isn't used for anything else, we still need to re-open the menu later. Best done if R_2=72 isn't behaving in some improvement sometime in the future.

Payment due: Two dreams.
We're not going to get this any faster. At least, not without something more crazy. I now feel this is optimal, at least by the methods I am using.
According to me, the Valley of Death fairies by this attempt reaches the last cave 287 frames faster than this movie produced by the Reflect Trek fairy manipulation. We just need Arc to copy in the last cave and Great Palace input and tweak things to fit with the RNG.

Uses R_2=71. Some small time lost to manipulation, but this looks pretty nice.
However, I'm not convinced I took the normal encounter optimally. We can delay the first fairy encounter by as much as 11 frames, so we have 12 possible gTimer starts on that normal encounter. We do this to do RNG stuff if necessary.

This ain't hacked RAM anymore. I've actually trimmed off several frames before the last traversed bridge (removing intentional delays), scattered the remaining delays across a few transitions, and granted a wish.
There are extra delays, including sitting tight for 20 frames positioning a spawn and a little more walking in the Valley of Death. For a fairy, I'm sure this is a reasonable trade-off. Now, I haven't checked how mean the follow-up spawns are going to be for the trap that follows, but look at that fairy!

Save state anchored. RAM was hacked to provide the initial RNG/gTimer pair, but this indicates it's worth continuing my search.
gTimer=18 R_2=15 ; gTimer could also be 20, so basically see if I can't trip over this using the prior screen transitions.

Picked a different RNG than the concept for the first fairy. It's faster.
For the second fairy, I delay exactly 5 frames across various screen transitions in order to spawn the fairy and have it fly mostly where needed. One frame later, and the 21-frame rule would kick in.
Out to the second fairy, I haven't actually ran the rest of the trek to know if the encounters behave on the way to the palace. Still, there's not a lot of possibilities to look at without moving past that frame rule.

The concept is reality.
I've taken the third entry of my table put out by my script found in this post. Which is 0 frame delay at the tunnel and 22 frames at the child cave. Also, I seem to defy my own expectations by spawning the fairy in slot 5, where I only output paths for a fairy in slots 0, 1, or 2 in that table.
Seriously, I just can't predict what slot that thing will appear in, and it is possible to pick a different lossless path using the same RNG/gTimer pair that spawns the fairy in a different slot. I also spent more time waiting than expected, requiring more path than I reveal from my script.
Regardless, this proof of concept by itself should save over 100 frames. Spawning a new fairy on our way out of town shouldn't be an issue with all the screen transitions. I will be looking into how feasible it is to spawn two fairies in a row and have them fly straight to our next trap (immediate 3x east travel for our west fairy). At least for the second fairy, the east fairy will always spawn in slot 7, and the west fairy in slot 5, as nothing else will be taking up our slots, so prediction will be more stable.

Additions include:
  • Predicting when a spawn occurs
  • Predicting the formation of the next spawn
  • Predicting what directions the current groups will move to
Hopefully the fancy numbers and boxes look pretty enough. The orange hexadecimal values by the cyan decimal timers is the RNG value used for determining what spawns. For fairy encounters, it depends on what terrain you're walking over (D0 F0 E0 F0 F8 FF), and it needs to be that value or higher for a fairy to appear. Theoretically.
The directions of existing spawns are color coded: Green means they will unquestioningly go that direction, while orange means they'll only go that direction if not aligned vertically or horizontally with Link.
Still tweaking my prediction algorithms. Currently, the piece of code that predicts the next encounter appearance is inefficient, as it will run through hundreds of RNG calculations every frame. Or, for that matter, while you're sitting there paused, as gui.register runs lua code several times per second when paused. I plan to inject timestamps and a bit of memory to avoid recalculating what we already knew a frame ago.
However, the active display is encouraging. I haven't detected further errors, so here's my current prediction script.
Oh, and one more thing. The script is set up to detect moments the RNG is reset. It'll print, to the Output Console, the RNG value and global timer every time it happens, as these are probably our sync points. Probably good information to know, as if these are identical to some previous trial, then you are almost certainly going to have identical luck. If these are the only constraints to the effects of RNG, then there's 2688 possibilities.

Still a prototype. I'm using integer versions.
Added a snippet of code that attempts to identify world map locations where an exit will drop you off at. One would hope this lets you know where you're teleporting to. Numbers in the bottom right may be of assistance. Additionally, for room exits, I invert the colors if it's 0x3F, and instead show a number from 0 to 3. That's the selector for our world map thing.
Then again, I don't have much experience with these glitches about somehow making use of alternative exits, so I haven't checked how viable the numbers I'm showing are. Also, there is a *known* failure with my script when we're talking about the Maze, as for some reason, the standard 0x3F I expect to see isn't showing up, yet it exits to the overworld. I have things to look at.

Work-in-progress script. I'm playing around with various designs and thoughts as I run the debugger to get information.
Included is something that tracks Link's position, gives two numbers for enemies and one number for enemy projectiles (Link's sword beams and fire shots aren't included). The numbers are damage to Link if he's hit, and how many strikes it will take to defeat an enemy at current attack power.
I also have HUD stuff at the top of the screen. Still working things out and making them pretty enough. I haven't even removed the TASEditor piece in the script, so pressing controller buttons will toggle the TASEditor stuff if that's running.
I've experimented with some registerexec and registerwrite code. One piece is enabled as of this WIP.
Finally, I have my script respond to when you press space by dumping out a list of exits and apparently related numbers. I'm not particularly inclined to disable that bit of code.

An alternate (faster!) route compared with the current run. It arrives at Dark Link's room 193 frames faster than the tweaked version of TASEditor's run posted earlier.
It is likely more time can be saved as this is a fairly quick & dirty run with many old pieces pasted together.
