Generation I Glitch Discussion / Glitch Pikachu cries in Yellow
« on: Yesterday at 10:35:01 pm »
I'm considering recording all of the glitch Pikachu cries by ID.

If anyone else would like to help, you can enter the following code for ws m.

Valid values only range from 0x00 to 0x29, which leaves the rest of the values as glitch sound clips!

Code: [Select]
ld e,xx
ld b,3c
ld hl,4000
call 3e84
ret

If we want to represent this with reasonable items, prepare:

Repel x (cry ID)
Poké Ball x 6
Fresh Water x 33
Master Ball x 64
Soda Pop x 45
TM05 x 132
Lemonade x 201

(1e 02 04 06 3C 21 01 40 3d 2d CD 84 3E C9)

Hope this comes useful for anyone else who would like to experiment!  :)

Edit: (Some) may differ depending on the location you play them.

Cool! Was that discussion publicly online? May you link to Silktree's theory please?

Yes, he said that in the Bulbagarden Forums thread I linked to above. Here's the direct link to his post  :)

Thanks Sato! ^_^

It would be really cool if Gold/Silver had a haunted house to explore.  :)

Indeed. Silktree suggests that the Haunted House would've been found in Olivine City and that its inspiration was possibly the Hijemi Castle.

Cool! Was that discussion publicly online? May you link to Silktree's theory please?

Seems like the Japanese versions have an unused header for a removed location, which was called 「オバケやしき」  Haunted House. The English versions erased this reference by replacing the header's string with "N/A".

Yeah, I noticed your comment and it made me really curious whether it inspired the Old Chateau in Generation IV. I've updated the TCRF page with that theory.

It would be really cool if Gold/Silver had a haunted house to explore.  :)

You're welcome! ^^

OK, I'll go ahead and add the new information/red sprites.

This sprite also exists in Gold and Silver. JohtoMap has a feature where it shows the sprites of characters and 3F is apparently supposed to look red.

Could you update the TCRF article's section with that spriteset? You could merge the 4 sprites into a single image, too.

Thanks for this! So by using the Game Genie code 3F4-52A-08A in English Gold you can replace the left-most Pokémon Center nurse with this NPC sprite. :)

I'm just a little confused, do you want me to add the red sprites to the article (as you wrote the sprite is supposed to look red) or a version of the sprites with no palette assigned? The confusion was from the TCRF article stating there is no palette for the NPC.

Generation II Glitch Discussion / Pursuit glitch
« on: March 22, 2017, 06:00:04 pm »
It looks like there is an obscure glitch involving the move Pursuit in Generation II that was documented by someone or a source named Uwasa Ishi (Japanese: 噂石). I'm unsure if it only works on the Japanese versions but from what I gather it seems like if you switch out a Pokémon with a status condition and it faints from Pursuit, the status condition will return upon reviving the Pokémon with a Revive.

I haven't tested this glitch yet though. Thoughts?

Pokémon Discussion / Pokémon Crystal unused character?
« on: March 22, 2017, 04:57:11 pm »
In Pokémon Crystal there is a character which I don't remember being used on any NPC, which I found listed on a list of character indices on the Pokémon Crystal disassembly (https://github.com/pret/pokecrystal/blob/master/constants/sprite_constants.asm).

This character can be viewed on BGB (v1.5.2) with the code 013F54D1 but the code working may be due to a presumable emulation error (as I tried the code on an Xploder GB with Pokémon Crystal on a real Game Boy Advance SP and it didn't work).

These are his sprites with the male character's palette.

General Discussion / Re: Yeniaul's Discord Server (and rules)

Naltronix and Torchickens, sorry for the group spam, Discord was shitting on itself.

It's OK! :)

Oh absolutely! My documentation is incredibly poor, so be warned. What exactly do you have in mind?

Cool, thanks! :) I will send you a PM about it.

This was originally a secret but I may as well share it now. Me and ISSOtm are working on something cool that started (coincidentally) shortly before your thread, and part of it (not all of it) involves obtaining Pikablu (a Pokémon modified to have Marill's sprite).

Would you like to team up on Discord? Thinking if we share our code it may help the project finish a lot faster and you can have the BGB save state of what's been done so far.

General Discussion / Re: The Member's Guide to Topiclessness

There are some interesting fake Pokémon cartridges on eBay. It could be that I just didn't look in the past, but my recent search patterns may have brought them up as I haven't seen them while casually browsing before (not sure if eBay has a filter bubble or similar).





The infamous Pokémon Chaos Black.



The infamous Diamond and Jade.

Wow! This is really nice.  :) Great job Pokéglitch86!

Where do you store your script to make it Ho-Oh even after you reset the game? I used meta-map scripts back when I did Pallet Town into Twinleaf Town.

The low chance is due to VRAM being read while the LCD is accessing it ; the 01 01 15 bytes are (at least partially) read as $FF due to the LCD having priority.
Eventually the read lands on a HBlank period and the evolutions succeeds.

I see, interesting.  :) Thanks for this.

As Crystal_ documented (thread, video), not every Pokémon's level-up and evolution data is taken from the ROM, and there are exactly four glitch Pokémon each in both Red and Yellow who actually take their evolution data from VRAM (graphics data).

This is the list of applicable glitch Pokémon, copy and pasted from the wiki article I have just written:

http://glitchcity.info/wiki/Arbitrary_learnset_glitch_Pok%C3%A9mon

Red/Blue

Beginning of pointer table=$3B05C

A (0xEA) (VRAM $8124) — It learns certain moves when levelled up with Rare Candies but no moves when levelled up in battle.
Glitch (0xEB) (VRAM $992B)
G'Mp (0xF6) (VRAM $852C)
94 h (0xF9) (VRAM $9A20)

Yellow

Beginning of pointer table= $3B1E5

'r ゥ (0xEA) (VRAM $8124)
4 h 4 (0xEB) (VRAM $992B)
ゥ ₽ A (0xF6) (VRAM $852C)
₽ (0xF9) (VRAM $9A20)

According to Okk and echinodermata, level up evolutions are read when there is data in the form "01 [level] Pokémon ID]".

http://forums.glitchcity.info/index.php?topic=5217.0

In Yellow, after entering a map or saving and resetting, the location of $9A20 may be taken from one of the screen tiles.

Very fortunately, 01 01 15 can be represented by block 09 in Cinnabar Mansion, and when it is at the bottom-left corner of the screen in this spot on 2F you have a chance of evolving ₽ (0xF9) into Mew at Level 1 due to the VRAM data representing evolution code to evolve it into Mew. (You must save and reset the game at this spot with your ₽ (0xF9))



Sadly for unknown reasons it's only a chance and a rather low chance at that it seems; your ₽ (0xF9) may evolve into Q or Nidoran♂ many times but never Mew, until you reset and try again hopefully to get a successful attempt. I don't know why and wonder whether it's to do with VRAM banks.

What's left to do now is test the other locations and whether this works on Red/Blue.

Edit: OK, you should be able to do this with 0xEB too except the data has to be in this green block and I'm not sure how easy that is to do as I couldn't align the 01 tiles and then that tree in the aforementioned map here.



Edit 2: 0xF9 confirmed on Red in addition to Yellow.
