Evie (ChickasaurusGL) 🌺 | Converting Attack experience into any Day Care Pokémon w/Box Breaker glitch (may be Red/Blue only*) @ChickasaurusGL | Uploaded September 2021 | Updated October 2024, 6 hours ago.
Notes: *It's not that it's impossible, but there's the possibility that glitch box pointers may be different in Yellow.
This glitch allows us to obtain any Day Care Pokémon, based on lower byte of Attack experience (Attack experience%256), which is converted to the species ID in Day Care; so 21 Attack exp would give Mew. ~ ^-^Note if you make it a divide by 0 experience group glitch Pokémon it can't be taken out, but none are known in EN Red/Blue; so in fact (if you can avoid HM moves on some glitchmon) withdrawing all indexed (basically all) glitch Pokémon+all Pokémon is possible (but not verified).
Another technicality; maybe if withdrawn at Level 1, 0; depending on species (eg. Level 0 'M 00) there could be a freeze(?). I didn't make note of what controls the level and experience, so later because it's late I can document that too.Another issue may be the nickname. In this video, my last stored Pokémon gave a glitched '9 9' nickname; I suspect that might be because I only had 1 boxed Pokémon, so maybe it was taking 9s (FF) from glitch Pokémon beyond slot 1.
This nickname could be problematic if unterminated (possible freezes if deposit it in PC, but not other places eg battle, less likely freezes in party summary but not discounted), but isn't completely unsafe; as viewing status of a Pokémon w/specific moves adds hex:50 in the buffer early enough to not freeze the game. However, sometimes an unterminated species name is good, as it is required for oobLG if you decide to perform it. A possible solution may be to have box filled w dec:80 (0x50) bytes for now until exact cause is found; so Day Care Pokémon is generated w/a terminated name.Depending on preference u might prefer this over the remaining HP glitch (a more elaborate glitch than the Pokémon merge glitch that's also possible with Charizard 'M (FF), which is longer, doesn't work if box 1 was completely full and (imo more confusing).
Reqs:
1. Item quantity of x255 (perform item duplication, and if you get x129 from a MissingNo., toss 2 and repeat the duplication for x255)
2. A Pokémon with a specific lower Attack experience byte (see above). You can choose what you want from https://glitchcity.wiki/The_Big_HEX_List and checking hex, dec.In Generation I, Pokémon gain Attack experience from the Pokémon's base stat (e.g. Magikarp has 10 Attack, so 10 Attack experience without Exp. All and/or switching Pokémon).Gaining exactly 1 Attack experience is more complex and I don't think it works intuitively(?), but I did it to get 21 from 20 by i. having 6 Pokémon, ii. the Exp. All (x1) and performing two switches before defeating Magikarp. It may actually save some time if you repeat this to get some Exp. All x0 (Exp. All x0 doesn't count, and the game acts as if you don't have it) and toss 255 from one stack to get a Exp. All x1 stack (since x0 is effectively x256), unless you don't have the expanded inventory, where you can just get leave Exp. All in the PC. Note we'll be corrupting the number of PC item stacks to 255, so for multiple use unless you have lots of Exp. All in one stack it gets messy, as making a new stack (depositing the Exp. All if no others are registered in the PC to exist) makes the PC item stack counter 0. Alternatively if you have a lot of time and you need to use Exp. All and/or switches, more encounters without having to deposit/get rid of the Exp. All will work, as expected.
3. An item stack x144, but it must not be the same type of item as PC item 51, as it will be moved there. Switching this stack to PC item 51 glitches out the boxes to make the game think we're in glitch box (dec:)16, which has the (move contents to) pointer FA35, but basically this will mean we'll be moving Pokémon data near where the Day Care data is.

4. https://glitchcity.wiki/Celadon_looping_map_trick - If u want Exp. All x0 stacks
Steps:
1. Set up the requirements and Attack experience of your choice, via encounters from a Pokémon that hasn't seen through a defeated Pokémon in battle before (e.g. a Pokémon you just caught that's at a high enough level to survive and gain the experience).
2. Go to empty box+deposit the Pokémon with specific Attack experience to current PC slot 1 (contents mb erased later).
3. Perform dry underflow glitch but in PC (see the article above for instructions).
4. Switch (unique) item stack x144 to PC item 51, now the box is in a glitched state (partially glitch box 16, but partially still the Pokémon we last had in the box).
5. Go to change boxes, don't move the cursor and press A ('switching box 16 to itself')
6. That's it! :] Go grab your cute monstrosity from the Day Care ^-^. It may be good to soft/hard reset the game (switching boxes already saved the game) just in case it freezes when you exit.
