Glitch Pokémon Species in the Gen 2 Leaks

Hello guys! I've recently joined the Glitch City Laboratories Forums, and I have decided to mess around with gameshark, and I eventually encountered this… thing. It's name is  "9A9YASEINO." I'll just shorten it to SEINO. SEINO. takes ?????'s place in the Gen 2 leak. I don't have much info on this thing other than it's similar to missingno. Here's a wild pokemon encounter cheat. Set the XX to 00 to encounter this thing. 01XXD7CD

"This only works in the Pokemon Gen 2 Spaceworld leak!"

Checks out on BGB. :)

I think a better name would be 9 9 though, or GSBeta:00. "Seino" is just the last two characters of "の" (or "の"), meaning wild. I'll see if I can find out more before someone else does.

Also, I figured out that it's sprite changes sometimes.

Can't wait to see what stuff ya'll will discover. Maybe some more glitch pokemon exclusive to this version?

Yes, it seems to be undetermined until you start battling it (or one of a few…this is the same sprite it had in your post, after all). It's probably reading from memory locations that are prone to frequently changing.

Its only move seems to be Struggle. What I want to know, though, is if it actually knows Struggle or just doesn't have any moves. But I'll have to catch it first, the old-fashioned way. :P

Just found a glitch trainer by changing the code to FF. This… THING…. changes the screen to black, some overworld sprites show up in random places, then after it tries to send a pokemon out, it crashes. Here's two screenshots.

Seems like this post just changed into Gen 2 Glitch Pokemon/Trainer findings.

I've been messing around a bit on the ROM myself thanks to this thread, but not in any goal-oriented way. I'll move it to general glitch discussion for now.

A RAM map for the Gold beta is here, as part of a disassembly of the ROM. Use this if you want to gather data along the lines of the GlitchDex.

And here are a few more curiosities from my end, just because. No matter what, I couldn't seem to catch 9 9. I must have thrown at least 500 Ultra Balls at it. Some screenshots (you should use BGB, by the way):

Hex 253 (252 freezes the game if you hit Start after selecting it) in the Battle Tester. I put it up against a trainer (Bug Catcher I believe) with a level 10 Bulbasaur, but ended up seeing a 9 9 instead, hybridized in some way with Meowth. On another attempt I got a softlock upon sending in hex 253, apparently due to glitch audio. This seemed to happen when I generated a wild battle rather than a trainer.

Super Nerd _づ sends in a Slowking/9 9 hybrid, meant to be a level 9 Bulbasaur.

Hex 253 enters the fray safely again, looking a bit different.

Hex 253 in the Pokemon select menu. So far so good. As the GlitchDex entry suggests, it's Water and Psychic type. And as expected, no moves.

Ah, try not to double post in the future, by the way. Use the "Edit" button.

Why not try and force the game to put him in the party? Here's some codes for future investigation.

01XXD7CD - Changes Pokemon You Encounter
[If I can find more, i'll put them here later]

I'm sure someone can come up with gameshark codes to change the Pokemon in the first slot of your party.

In line 936 of wram.asm, we have
wPartyMon1:: party_struct wPartyMon1 ; d6b2

Having just started a new file, I can see a Cruz (hex 9E) in my team, and surely enough address $D6B2 is 9E. :) So that would be how to change the species. I'll get back to this later.

Well, at least we can add more to the glitchdex once we find all of the glitch pokemon in there. ^-^

By the way, please do not use VBA.

I'm disappointed, Isso. I expected more righteous indignation! :P

Oh, by the way, these seem to already exist after all, thanks to Evie/Torchickens:

Learnsets and other tidbits are still needed, though.

FC's Dex entry.

FD's Dex entry. Its cry upon encountering it is fucking FIRE. Would totally listen outside the game. It becomes Bulbasaur's otherwise though.

[img]https://i.imgur.com/0eScpLl.png[/img]
00's Dex entry. A note on this one, though: I had to change CDD7 to 00 using Seino's code while already battling FD in order to catch this one. Otherwise, it will break out of a Master Ball. Interestingly, sometimes it will shake once or twice. The "stars" animation while throwing the ball still plays. In a similar manner to 'M, the battle continues after catching it. Whatever was causing the catch rate to be the other Pokémon's was no longer in effect by that point, though.

FE's Dex entry. Similarly to 00, I had to modify the enemy species while in battle to catch it, but in this case it was because loading the front sprite freezes the game.

Aaaand FF's. Same deal with the freezing. Nothing too interesting in the end.

They all turn into Bulbasaur when caught, name included. So the Rhydon error trap still works the same way as in RBY.

Great research SEINO and Sherkel! :)

Yeah, I decided to document these glitch Pokémon (other than glitch Unown) on the wiki but haven't added the TM/HM moves yet.
