Generation II Glitch Discussion / Re: Editing CEE0 for many cool effects (English gold)
« Last post by ISSOtm on December 12, 2017, 06:55:49 pm »
The effect of swapping Pokémon past slot 6 is already possible using Bad Clones, so I'm more interested in the other effects.

Maybe they could be doable "legit" (I'm not really interested in memory edit-only glitches, but that's probably me being too much of a purist) using DMA hijacking, and half-resetting the game by jumping in the middle of its init (past the point where it copies the DMA routine, maybe setting a few values beforehand to avoid crashes).

If a modified init is required, the Mail buffer could lend a helpful hand here, by providing a large enough buffer to store the modified init in.

Here's a "guide" that would allow doing that :

Quote
1. Run this code (it's inexact because I don't know the labels and lengths)
Code: [Select]
ld hl, Init ; 0150, IIRC ?
ld de, wMailBuffer
ld bc, MailBufLen
jp CopyMemory ; Copy the "base" init to the buffer
This sets up the code buffer for later.

2. Edit all addresses that have to be patched. You can use the "box names as a memory editor" setup.

3. Write the DMA hijacking routine, which I'll call "SetCEE0ToValue".

4. Run this code.
Code: [Select]
; Set up DMA hijacking
ld hl, PiggybackSnippet ; Must point to "call SetCEE0ToValue" followed by "ld [c], a"
ld bc, 4 << 8 | LOW(DMARoutine)

.copyDMA
ld a, [hli]
ld [c], a
inc c
dec b
jr nz, .copyDMA

jp wMailBuffer ; Run our modified game init (which should have been tailed with a jp to ROM)
It's required to set DMA hijacking at the same time as "rebooting", since otherwise you can't do ACE due to the cursor being locked.

"Pokemon" beyond the sixth slot are merely other, unrelated data being expressed as Pokemon.
I know that, that's why I said you can switch them with real Pokemon
23
Could some thing like the game memory hacking itself rom hack be done with 8f it would be cool to see the game glitching itself on a real cartridge.

...

????????

I'm going to assume you're reffering to a ROM hack that alters data pseudo-randomly, in which case, no, that cannot be done with 8f under any circumstances. If you want to make a ROM hack, use pokered.
Yeah, it adds some register mixing to VBlank. That's not RAMable.

Auto input is what's used in stuff like the DUDE catching tutorial. It's controlled by a few addresses. Due to the trainer being a glitch, it will take most of its data from unrelated memory addresses, (including what she says). In the video, you can see the trainer class is a glitch taking some data from the move descriptions or TM descriptions (Zap cannon comes to mind) and in the video the player uses a GS code to change the trainer class to a valid one in order to fight her. Back to auto input, due to it taking data from unrelated memory addresses, the battle may have been flagged as a auto input battle, or the memory address corrupted by the glitch textboxes. Hope I answered some of your questions  :)

Generation II Glitch Discussion / Editing CEE0 for many cool effects (English gold)
« Last post by 0ErrorYT on December 11, 2017, 08:07:33 pm »
CEE0 determines the cursor position in most menus. Changing it to values higher that the amount of options in the current menu allows you to select invalid options. Here is the effects I have found:
Access Pokemon beyond the sixth slot:
Using CEE0, you can access Pokemon beyond the sixth slot. You can switch them with real Pokemon (you will lose the Pokemon you switched). So far I have found a Raikou/crobat hybrid, a Rhydon with a very long name, and many ?????. If you choose a blank party space, it appears to be the last Pokemon deposited (?) however the species is changed to ????? (00)
Unlock Mystery gift: Using CEE0 in the start menu doesn't cause many noteworthy effects, except option 00, which is Mystery gift. After opening Mystery gift, the option will be there after you reset.
Glitch names and Sprite glitches when selecting 10+ characters names
Using CEE0 in the introduction when selecting your name allows you to select 10+ character names or blank names. (Example: DriMOMREDGREENMOM) If you select a 10+ character name, sprites will glitch up depending on the amount of characters.

Generation I Glitch Discussion / Re: Pokemon Yellow "Save Abuse" Glitch

In theory you can change it if you deposit a Pokémon in the box, followed by Q, followed by the Pokémon you want, followed by the Pokémon with the colour you want, then withdraw the first Pokémon to apply the effects on Pokémon 3.

What slot was that Dragonite in? If you know the exact slot I can look into what controls its colour for you. Its possible there's something about that Dragonite's species byte 2 being easy to change. A lot of data beyond slot 6 actually isn't Pokémon data at all, hence why it could change so easily.

At the moment, Dragonite is #1 in my party, but I think I originally found it (it "became" part of my team like a year ago) somewhere in the 20's. If it's fainting cry is any indication, it's a Mankey hybrid.

Depositing things into the PC won't work, because the game crashes when I try to do so.

General Discussion / Re: The dream thread
« Last post by Epsilon on December 11, 2017, 04:45:13 pm »
Had a dream last night about having to rig an entire city to explode using the electrical systems to stop Ajit Pai from going through it so he couldn't end net neutrality. He never showed because he took a different route.

I guess you could say the city got...

...throttled
I can't wait for the sweet release of death

Regarding the thread, the other night I recall having a dream where I was at my friend's grandparents house. I walked into their guest room and I happened to notice a very large, very old TV. When I turned it on, I realized that the TV displayed past events as they happened. Mainly disasters, such as nuclear meltdowns and hurricanes. Near the end of the dream, I got greedy and stole the TV for my self. I plugged into an outlet on my garage. When I did, a green couch appeared behind me, but the TV simply showed a static image. I proceeded to stare at the static for the remainder of the dream.

Rather odd.
