It is possible to do so with ACE - you'd need to write to the two bytes containing the Trainer ID - but I'm not a Gen II ACE expert, so I'll pass. (And writing the "save restoration" 8F sucked up all my energy x)

First you'd have to choose which method of ACE you pick. There are a couple different ones, one requiring for example two Secret Potions and two Machine Parts to get TMs in the wrong pocket. I think that can be done with cloning, but the "standard" way of doing it is by trading. But if you have only one game/console, you'd have to use another method, etc. I don't think they are mentioned on the wiki (yet).

This is I guess an early warning to the people who use this thread or help people who ask questions on it and have not realized this already but it is going to light up soon with people who got gold and silver virtual console trying to get lots of good and shiny pokemon into sun and moon and in November ultrasun and ultra moon.

when trading from gen 2 to 1 using johto guard, do the type bytes of the pokemon stay the same, or are they set to whatever type the gen 1 equivalent is?

ie: use johto guard to trade lugia to gen 1, is it still psychic/flying type?

Most likely, as IIRC the type bytes weren't shuffled around between the two. Give it a shot!

Since they aren't shuffled usually, I bet they don't.

Yes. When converting the Pokémon to Generation I format, the Generation II game looks up its types from its own data. (An exception is made for Magnemite and Magneton.) This also means the resulting glitch Pokémon can be traded back to Generation II and become a Lugia again, since the type data is used to check whether a Pokémon is abnormal.

Thanks, I was wondering if I could get 2 lugias by trading one to blue and having a wild ghost missingno copy its type.

Hm, but the lookup will fail for Pokémon not in the table, no ?

Pokémon not in the table when traded from Generation I to Generation II convert according to values extrapolated beyond the table. According to Hacky for Pokémon not in the table traded from Generation II to Generation I the game searches until it finds the relevant Generation II value beyond the table (so for Celebi it would be FB, for Egg it would be FD and for the ????? 00, FC, FE and FF I think).

The offset will then determine the Generation I Pokémon. For Celebi and Egg in English Gold/Silver, the game searches beyond the end of the ROM bank and into RAM, which is why the predictions are hard to predict (apparently much like CoolTrainer's success rate).

Lugia is defined in the table so that MissingNo. (Ghost-form) converts into Lugia and Lugia converts back into MissingNo. (Ghost), and since MissingNo. (Ghost) can copy the stored types of a Pokémon in the party after catching it if there was an (internally stored) Psychic/Flying Pokémon you could use that to trade MissingNo. (Ghost) on to Generation II (another method  is by using arbitrary code execution to change the internal types).

I believe the abnormal Pokémon trap doesn't apply to Generation II to Generation I trades, so the game won't mind in that case that Lugia is Psychic/Flying and MissingNo. Ghost can be a different type. Therefore in theory, as DoubleNegative says you should be able to get two Lugia by trading one (via Time Capsule exploit) to Generation I and catching MissingNo. (Ghost).

Did we reallyexpect anything else? Honestly?
ISSOtm, why did you have to ask? This IS Gens 1+2 we're talking about here.
