Keep in mind that though it will involve constant shutter-clicking, but it will be utterly, smacktackularly fast. By your logic, the Super Mario TASes are frame-perfect running with the occasional jump. Yawn. Let's make this more of a demonstration of the highest scoring things you can do. With only 1 photo ever taken of any pokemon, it would be interesting. Having this game on hard copy, I've often taken 50 shots of the same thing hoping one will work best. Here, only 1 is necessary. Unfortunately, I do see one drawback: Each level must be played 2-3 times. Here's a sort of "route":
Level 1 (beach):
Get a photo of Lapras in the background each time it appears. This'll shift it closer, until the best shot near Kangaskhan. 3430 points.
Get a fluke photo of Butterfree (All good photos are taken by luck). 4960 points.
Get a nice shot of Eevee. 4500 points.
Snap a photo of gust-using pidgey. 5100 points.
Total of 17990 points. That's enough points for the apple item. Perfect, because one of the best pokemon for score is Electrode.
Do nothing until there's a chance to hit the second Electrode in the tunnel with an apple (If it wastes no time, shift the camera to watch Pikachu and later Electabuzz get pwned). Get a shot on the frame with maximum size bonus. 5150.
The blast knocks Kakuna off the ceiling. The best shot is worth 4540.
Get a shot of Haunter. Again, the best shots are flukes. 4000.
Get 3 shots of Diglett, one each time he pops up. Not for score, just to make Dugtrio come out. 3 dugtrio, 9 moles in total. Dugtrio is worth 4780.
Get good shots of Magnemite then Magneton, and then pick off the Electrode at the last moment. Magnemite and Magneton are worth 4260 and 4000, respectively.
That's 44720 points, total. No bonuses this time.
Level 3:
At the start, the first Rapidash might be possible to lure into a shot with the 2 other Rapidash in it. In any case, Rapidash is worth 5170.
Vulpix can be lured together with apples, so they should be. 5020.
While we're waiting, throw an apple between Magmar and Charmander over there, to watch Magmar KO Charmander. Charmander evolves (WTF?) into Charmeleon and pays back the favour. Not a photo, just funny.
At the first possible moment (I think that's best) throw an apple at the Moltres egg. The best photo gets 1350 pose, 1000 size, and technique bonus for 4700.
Throw an apple between the 2 magmars, and snap one attacking the other. 6710.
Get a photo of Charmeleon celebrating as you give it an apple. 4400. Then knock him into the lava! He'll evolve into Charizard, which can be hit with another apple. He'll do a fire attack, worth up to 4380.
That point total is now 75100, barely unlocking Pester Balls (75,000).
Level 4:
Hit Bulbasaur of those stumps with Pester Balls, and use Apples to get the best points. Worth 5380, more than the alternative (Poliwag).
Get a picture of the first slowpoke. Something's worth 4400, but I don't know what.
Don't bother evolving the second slowpoke... yet...
Knock down the last Metapod for long enough to hit the Psyduck, knock down the other 3 Metapods, and snap a photo of Psyduck leaping out of the water. Hit the Metapod to hit it up (originally was "knock" but... yeah...), then maybe hit it back down for a shot. 4470.
Hit those 2 porygon with Pester Balls to reveal the hiding places and get photos. 5610.
Congratulations for reading this far. PM me this phrase: "Quartz jock vends BMW glyph fix" to get mentioned in my signature.
Hit the Porygon over the switch (why the hell can't you get out and touch the switch? dumb) to unlock level 5.
That's 94960 points.
Level 5:
Get shots of 3 Zubat at the start, for points at the end. Get shots of the 2 distant Grimer.
A grimer appears quite close on a ledge. 4300. Evolve him into Muk with Pester Balls for 4000.
Unmorph all 3 Ditto with Pester Balls and get a shot of them close together. 4940.
Get a nice photo of Koffing chasing Jigglypuff, then pick him off with a Pester Ball. Get a shot of that. Then kill the other two, more distant Koffing. 4400.
Evolve Weepingbell. Photo. 5900.
Get a photo of 3 Zubat flying toward the camera near the exit. 4330.
Get the 3 jigglypuff singing. The photo is worth 6480. Then quickly end course before the long exit animation plays.
Big level - boosts the score to 129,310.
Level 6:
Hit all 3 squirtles with Pester Balls. They get hit onto an island and you can get a photo. 5260.
Throw pester balls in the water for Goldeen, Dratini and Magikarp. Worth 4400 each (evidently 1000 size and 1200 pose).
Throw a pester ball onto a distant spot where a Magikarp flops around. He'll flop onto land, a mankey will punch him, and Magikarp flies over the mountains.
Hit the Geodudes with a pester ball to get Sandshrew. Get both Sandshrew together and happy, they're worth 4990.
There are 2 more distant Geodudes. Hit them with Pester Balls and they fall, knocking off a Graveler, revealing a Sandslash. Give him an apple for a good pose. 4800.
Go down the steep valley. Look over to the ledge there, and you'll hear "eeeeeeyyooooooooo... thud... buh-karp-karp-karp". Nice hangtime, Mankey! Hit the Magikrap (typo intended) with a pester ball, and he'll evolve into Gyarados. Gyarados is worth 4680.
Get a centered photo of Staryu, then another as he comes near you. Then repeat for the other two. Then get a well-timed shot for 3730.
The Staryu go into a whirlpool. They come out evolved. Get a shot of them flying away for 4380.
Throw multiple pester balls into the whirlpool (it flashes if the shot worked) to get Dragonite. The best pose is with his mouth open roaring. 4400.
There's a Squirtle over there. Hit it with a pester ball to send it up the mountain, hitting Mankey off. Later, you can get a shot of him for 4500. But it might not be worth it until you have dash, because you need to get the secret exit. However, the score is so close to getting the dash engine, at 174,750, it's worth snapping him for the dash engine. Then nail him with a Pester Ball.
The score will be 179,250 at this point. I have written more than I ever have before here. This post took about 2 hours to write. For now, it's generally:
get the poke flute and snap whatever you missed in the earlier levels. Get level 3's pokemon sign, it's at the start. Throw a pester ball into the mini volcano for koffing smoke.
