could you tell us the story of your shiny competitive latias in gen 3? im so curious

oh yeah so the reason i didn't go in depth about that in the post is it's actually quite a lot of obscure game mechanic talk and i didn't wanna divert from the heartwarming story to break people's brains potentially lol but yeah sure! i'll put the whole explanation below a cut because it's pretty long. warning that i'm going deep on the nerd shit sorry in advance LMAO

essentially the latias i use in gen 4 was obtained in pokemon emerald and then transferred through the pal park, i obtained it by combining ACE (arbitrary code execution) and RNG manipulation. neither of these things are hacking or require any sort of tampering with the game and can be done on original hardware (i did all this on my original emerald cart in an actual GBA SP) but it is an unintended way of playing the game, just to be upfront, not that i mind because i'm doing singleplayer stuff for fun.

so, RNG manipulation is the process of perfectly timing your button inputs and actions to get the game to spit out the "random" result that you want. because computers struggle to do true randomness (especially something as old as generation 3 pokemon games) usually "randomness" is actually based on elaborate algorithms/equations. in emerald, the game is supposed to choose a "seed" to generate random pokemon spawns etc with (think minecraft world seeds and how those generate a world, but with wild pokemon and stuff instead if you've ever played minecraft!) based on the RTC (real time clock) of the cartridge, but due to a programming error, emerald actually never seeds properly, causing it to always be stuck at a seed of 0. there have been a couple methods discovered to force the game to seed but that's irrelevant here. since the seed is always 0, every time you play emerald, all of the possible spawns are actually the same each time. to a casual player they will never notice such a thing but to an rng manipulator this becomes very, very useful.

when you get into a wild encounter (or obtain a gift pokemon, encounter a legendary, etc) the game checks what frame you're on since you booted the game, tosses that frame into its random number generating algorithm against the seed, and then every aspect of that pokemon is determined by the result, like IVs and nature and etc. so, if you were to backwards engineer this algorithm and then figure out a way to perfectly time your A press to hit the exact frame you want, you'd be able to get any IV spread etc you want... and you'd also be able to predict and time your inputs to get shinies assuming that you know your SID (secret ID, a hidden value paired with your trainer ID on your trainer card) which can be figured out through a variety of methods that i won't get into here.

as it turns out, the pokemon community is nuts and the whole backwards engineering process was already done by people way smarter than me, and software has been developed to be able to sift through all possible pokemon encounters in pokemon games, including emerald. i use PokeFinder which is by far the best program out for this right now that is getting consistently updated. software has also been developed to time your A presses, the main one i use is EonTimer which lets me pop in what frame i want to hit and it calculates the amount of time i have to wait and then beeps to tell me when to hit A. i feel the need to repeat again this software does not require you to tamper with your games in any way - i honestly highly recommend trying it sometime even if just for the novelty of getting a shiny to appear on command, it's really fun and there's tutorials on youtube by "i'm a blisy" dsfjfdskd

edit: here's a screencap of what eontimer looks like btw! not the same target frame i used back when i got this latias but yeah. it's neat

with all of that out of the way, it sounds like it should be as simple as saving in front of the latias and then looking up the spread i want, popping it into the timer, and then resetting my game, waiting for the beep, hitting A and rinse and repeat until i get it. there's a few holes in this plan though:

the spread i want (timid 31/31/31/31/31/31 AKA perfect IVs) would require me to leave my game on for literal weeks on end per attempt, which is entirely unrealistic and unfeasible. i'm doing this on actual hardware, no speedup!

the spread in question also isn't shiny with my current SID. i don't need the latias to be shiny or anything, i just want it to be for fun

i am using my emerald save file that already has the roamer Latios generated, so i no longer have the option of rng manipulating that one. this means i need to get to Southern Island and RNG the latias there... which is a mystery gift. i do not own the e-reader nor do i own an extremely expensive eon ticket to get that event in my game

and this is where ACE comes in! ACE is... complicated. if you've ever seen people pull off some excessively wild and glitchy stuff in gen 1 by swapping items around in their inventory, you were probably watching a form of ACE in action. it's the process of glitching the game into a state where you can get it to take some form of input from the player as code and then run that code, hence "arbitrary code execution". honestly ACE is not something i have studied in depth, especially with gen 3, and i mostly just followed tutorials on getting what i wanted. i can summarize this process down into a few steps:

getting the NPC trade pokemon DOTS the seedot and EV training it to a very specific spread

performing glitzer popping (wild name, i know) to corrupt DOTS the seedot into a very specific glitchy egg

changing the name of my PC boxes to what is essentially GBA assembly instructions

cloning the aforementioned glitch egg using the emerald battle tower cloning glitch a bunch of times so i can use them whenever and then hatching them, which due to the EV spread i gave DOTS, will execute the code i changed my PC box names to!

i used ACE to solve all of the aforementioned problems with this rng manipulation.

i used ACE to make my game jump thousands upon thousands of frames forward, just a little bit before the competitive spread i wanted, and then went to the battle frontier to save a battle video at the battle factory by going in and instantly losing... this is because every time a battle video is loaded, it doesn't actually save every random result that happens in the battle (like missing and damage rolls) and instead just remembers the state of the RNG before the battle started and player choices and re-calculates the same exact random chances. therefore, if i watch this battle video from the trainer card upon every reset, i will jump back to that place thousands of frames forward, right before the latias spread i want

i used ACE to change my SID to a value that would make the spread i want shiny in combination with my TID because why not

i used ACE to spawn latias on southern island and to give myself the eon ticket to get there, no real life eon ticket/e-reader required (there are ways to inject this event that don't require ACE/the real life event items but i wanted to do all this without tampering!)

as a side tangent, i should mention that i had a very obscure problem with running the ACE to get to southern island that i had to contact some gen 3 ACE experts for help on... too complicated to explain here in any sort of legible way i think, but basically the problem was every time i hatched the glitch egg, the game just froze despite my code being typed in properly in my PC boxes with no typos. the audio kept playing but it would hang on the hatching screen, resulting in this extremely cursed footage of me hatching a void egg that looked like nothing and caused my game to crash:

i just think that's neat LMAO. anyways yeah after getting all that complicated ACE shit out of the way that took me 123989123 years to set up, it was just a matter of standing in front of the rock on southern island, saving my game, getting my timer ready, soft resetting my game, watching my battle video and starting my timer, and then waiting a handful of seconds and trying to press A with the exact 1/60th of a second timing to get the latias to appear. (emerald runs on 60 fps, this always takes a few tries)

(i can't put 2 videos in a tumblr post but if you want to see the encounter happen, i took a video here, it's a direct discord file link lol)

after that i simply transferred latibreak through HGSS pal park and trained her up and started using her in the battle tower :) technically a player could randomly stumble on this latias if they left their game open long enough and had the right TID/SID, it is a completely valid encounter that can move through pokemon bank and pokemon home! i just used a variety of game knowledge and glitches to get it to appear for me without having to wait for luck. i hope any of this made sense and sorry for all the jargon!! i wasn't sure how else to tell this story tbh. if any of this sounds interesting to you i highly recommend trying out at least rng manipulation sometime! you can do a lot of cool stuff with it even without ACE being involved, i just really needed ACE for this specific pokemon i wanted SDFJFDS

Journey through Paldea part 4

After some traveling I finally made it to the city were I be staying at. But before I entered Nemona wanted to battle me again Which I accepted.

She sent out the grass cat which was easily dealt with Sabrina and Ammit combine power. Next up was her Pawmi which he terrazise. Giving it a neat hat. i sent out Sabrina and one shot the Pawmi. After getting it with a boosted thunder shock of course. Has that was done we entered the place. A place filled so many shops.

She ask me what I wanted to see which was of course the food. She left to get me something which left me to explore. Has that was done we met up at the front of the academy.

has I went there I spotted a girl with the best backpack ever being annoyed by two people from a group called team star. I like the shades but those helmets got to go.

I stood up for her. Which gotten them mad.

Even more so when I said I had no idea who they were.

So the challenge me the first grunt was no problem for Sabrina and defeated her. Next grunt was up next till Nemona showed up.

Who thought I was picking fights when really it was team star. Which she understood.

She gave me the device needed for the hats and let me take care of the grunt has a tutorial. Something the grunt was mad about but was silence by Nemona saying if you don't like it I could just fight you instead.

Has the battle happen I went to try out the hats gimmic. Making Sabrina pure fairy. Which again destroyed the grunt.

The girl thank us and left. Which Nemona commented the pure truth. Eevee bag is supreme.

Has that was done we went to class. Which I introduce my self to it. Saying that I love everything about pokemon. And that my dream is to be a strong trainer which Nemona liked. Has that was done I went to cafeteria because food.

Which led me to meating Arvin again. Which give the choice to help him to find mystical herbs. Which I said yes before he even explain. In which he called me a maniac. Which ya I am and proud of it. After he left my phone was hack a mysterious person ask me to be part of operation Starfall. Which I agreed to has that was over the director ask me to be carful when talking on the phone. Being I was being so loud everyone could hear me. After that I went to the teaches room and talk to Nemona about taking on the gym challenges which I said yes to.

has that was done I went to class doing them all that was available. Acing there questions.

The director called for me after words. Which amounted to Arvin mom asking me to look after the cool dino lizard.

Has that was over we went to our dorm room and time skip to the treasure hunt which is a study thing. Having us roam around the region.

After that outside of the school Nemona and Arvin argue about who is getting me . Which then the person who hacked my phone dub cassie being I cant spell for shit and I don't want to keep looking up how to spell her name. Rang up right in the middle of this convo and talk about team star. Which the other two gotten mad which Cassie made them silent by saying hey its up to me to do what ever. Clearing the person with the brain cell in this weird friend group.

Koridon went out of the pokeball due to hearing sandwich which fair I do that to if I could. Then it gestured to me riding it which is pretty cool.

has that was done. I went to south province two. To get my first gym badge and get two members I knew would be part of my perma team. A Nymble name Kotaro which replace Jessica. And a Charcadet named Proto who replaced Pigsy. During that Ammit evolved. Making me ready to face Katy.
