Yeah, of course.
New update with Pikablu and Pokedex entry.

Unfortunately, I got the code together too late for April 1st.
Oh absolutely! My documentation is incredibly poor, so be warned. What exactly do you have in mind?
Yes, I'm just using the code Mr. Cheeze wrote, but I have it calling another script before returning back to OAM.

I actually was originally disguising a Seadra as a Marill (named Pikablu of course)! But then I decided to switch to adding Ho-oh instead. I think for version 2 I may make it a Pikablu rather than a Ho-oh, as well as getting Mr. Cheeze's virus working with my code so you could trade that Pikablu to a completely unmodified cartridge.
The first two bytes of the OAM DMA routine are replaced with a jump command which eventually leads to the custom code. The two bytes that are over written are suppose to load C3 into register A, so we do this in our custom code before returning back to the OAM DMA routine. The custom code just ensures graphical changes are made under the right circumstances, such as copying Ho-oh's sprite (that we have stored in empty save ram) to VRAM where it will be displayed.
I believe it is a meta-map script. It is a modified version of Mr. Cheeze's mew truck save virus with much of his code still remaining, though currently unusable. The map script modifies the OAM DMA routine and the OAM DMA routine then modifies the map script keeping everything running even after changing maps or saving and resetting. Running custom scripts during the OAM DMA is what is doing the bulk of the work rather than using map scripts.

I'm really no expert on how the GameBoy addresses and uses it's RAM. I would imagine that it uses it's own internal RAM up until you hit save at which point it transfers the updated save file to the cartridge RAM. Perhaps the glitch somehow instructed the processor to address and write to the cartridge RAM which would had corrupted the save file.

Try cloning Red Gyarados. Always seemed to work pretty well. Some pokemon definitely work better than others. And again, you can use any "bad clone" for the Celebi Trick. For example if you had a Sneasel with Beat Up you could use a Gyarados bad clone as a substitute for the Sneasel bad clone and it'd work. Of course I recommend getting a non hybrid ????? and just using that.

I've never gotten a corrupted save file from the many trials and experimentation I've done with ?????. Does your cart still save? Most Gen 2 cartridges have gone bad by now. The batteries on my Crystal, Gold, and Silver have all ran dry. My friend has a gold version with a save file that's corrupted but will still load and eventually freeze after a little gameplay. Chances are it can modify the save file with the correct conditions but it seems it happens very rarely. As with all glitches proceed at your own risk.

A bad clone and a ????? are very different. It's sprite represents whatever data somehow got shifted into that location in it's data structure. Kingdra seems to be the most common "random" sprite. It's certainly notable that Kingdra's hex value is the same as the "?" character. It's essentially one of the many question marks that spread over the entire screen finding itself within the sprite data. Why are there so many question marks being generated? Perhaps they come from the name "?????" but I would imagine it's some sort of error code the game spits out.
Generation II Glitch Discussion / GSC ????? FC, FD, and FE Research
« on: February 01, 2013, 01:10:01 pm »
I was wondering how much research/experimentation has been done with the GSC glitch pokemon other than FF or 00 (FC, FD, and FE). They should be obtainable through in-game means between the Celebi Glitch and the Name Trick along with perhaps importing glitch moves with corresponding hex from RBY. I plan on finding an in-game means of obtaining them and begin experimenting with them within the coming weeks. However, if anyone knows information (or where to find information) regarding these pokemon it would be very useful and appreciated. I will post any of my own findings within this thread.

I think this is the method I used involved hybridizing FF with another pokemon to get rid of FF. Once hybridizing FF would then appear to be a normal pokemon and would be recognized by the PC and you can deposit/release it normally. (As a hybrid) Another otherwise normal pokemon will have hybridized with FF and appear to be an FF. Just put it in and out of the daycare and it will be normal again. I have organized instruction saved in a word document somewhere..

Thanks MysticFlygon for this much deserved thread. There is a lot of misconceptions about what a "bad clone" actually is and I'll try my best to clear those up along with writing up a bunch of stuff that I never got around to. This will make experimenting with these glitches much easier. I originally began to experiment with 'bad clones' in order to achieve a means at obtaining a g/s/c missingno or ????? in order to make the Johto Guard Glitch a viable glitch. The original discovery/discussion thread can be found here.

A bad clone is just a pokemon (the one you are cloning) that has been hybridized with the cancel button (It's my working theory at least). Either that or it's just a corrupted version of the pokemon you tried to clone. The cancel button is in fact hex FF or 255 which marks an end of list. In this case the ????? (FF) is the actual pokemon that has now been hybridized with your attempted clone. All the "glitchyness" is the game filling in a bunch of pokemon data that of course can't be found inside the cancel button data or perhaps it's just corrupted data as a result of shutting the game off mid-save. Problems with this theory are that bad clones follow the characteristics of ????? (00) rather than FF. I really don't know why.

The useful application of a bad clone in my mind is not for any Celebi Glitch or Hybridization or Name Trick but rather to get a clean ????? (00) and ????? (FF) which is much more useful and easier to use as they do not contain corrupted data. This is rather easy. All we need to do is take the 'bad clone' and breed it with a ditto. This will result in an egg that may take a while to hatch but will eventually hatch into a ????? (00). I believe it is also wise to give it a rare candy once it's hatched. This will prevent it from jumping up to extreme levels when put in the daycare. That is how one can obtain a clean ????? (00).

A ????? (00) has useful applications but it's ????? (FF) that acts almost just like a 'bad clone' and can also be used for the Johto Guard Glitch. You can convert 00 into FF by having 5 pokemon in your party and then taking 00 out of the daycare. You then move 00 to the top of your party and use move pokemon to insert a seventh pokemon into your party. (I call this overloading). Go back to the daycare lady/man and give them your 00. It this then recommended that you release the top pokemon in your party as it will be very corrupted. Your 00 should now instead be an clean FF which is a bit more useful.

Here's how 00 and FF can be distinguished. While 00 or FF is in the daycare FF's overworld sprite outside will be a bunch of arbitrary pixels while 00 has the hero's sprite.

It should be noted that you cannot deposit either 00 or FF in your PC. You cannot even use the PC to delete them unless you do some clever hybridization in which case you can completely rid yourself of them if you so choose. An egg of either 00 or FF can be deposited into the PC so that you don't have to get a bad clone all over again. You can get a FF egg by simply breeding FF with a ditto.

There's probably more I have to say on the subject or g/s/c glitches in general but this is what came to mind at the moment.

I believe I had achieved hybridizing pokemon in the PC at some point, but I didn't look further into it as I was currently focusing on something else. If I remember correctly I was using "Move pkmn" to move pokemon between boxes and cutting the power midway while it was saving. I can confirm that you can successfully get a "bad clone" using this method and have been meaning to try this on my silver. I think what caused hybrid pokemon for me is when you place a pokemon somewhere in a box but not the very bottom (As this would have the same effect as normal PC cloning). I'll try to look into this enhanced cloning glitch and properly test it. Out of my Gold, Silver, and Crystal my Silver is the only one that's battery is still going. I replaced my Crystal's battery five or so years ago and hopefully it'll last a few more years.
