Transferring data from Gen 2 to Gen 5?
« on: June 03, 2015, 10:08:11 am »
CGB has an IR Port.

Gen 5 Carts have an IR Port.

Transferring data from Gen 2 to Gen 5 confirmed?

(In all honesty, it probably isn't possible, but you never know...)

I don’t have a Gen V game and know nothing about its IR protocol, but my bet would be that it’s technically possible. It may also be possible to emulate the Pokéwalker’s IR communication with HeartGold/SoulSilver. Now I’m tempted to go buy stuff.

The game Mission: Impossible included a function to use the GBC’s IR port as a TV remote control, so at the very least it should be possible to do that with Gen II arbitrary code execution. (Edit: Or non-Japanese versions of Yellow, since they run in CGB mode.)

You can't do anything with HG/SS Pokéwalker, because Sanqui said that HG/SS only sends video data to the Pokéwalker, and not actual Pokémon data. The actual Pokémon data is saved for when the Pokémon returns.

I'm not so sure that you could transfer Gen 2 Data to Gen 5 because the Pokémon Data Structure for Gen 5 is unknown. Of course, if you can make something happen by using the GBC IR Function, that would be progress.

I knew that the Pokémon data is kept on the HG/SS side, but there are other possibilities.
  • The best-case scenario would be if there were a bug in the code handling Pokéwalker data that would allow arbitrary code execution in HG/SS. That would be nice.
  • When two Pokéwalkers communicate, they exchange the players’ party data so that the other player’s party will appear in the Trainer House in Viridian City. With IR spoofing, it should be possible to change the Trainer House data and maybe put level 255 glitch Pokémon with glitch moves in there.
  • Alternatively, it should be possible, albeit a bit pointless, to manipulate the Pokéwalker itself. Maybe put a Missingno. sprite on it?

Hmm? You don’t mean this data structure, do you?

It’s always been my goal in life to make something happen :P

Ah, didn't check any other sites for the Gen 5 Structure. I only looked at Bulbapedia :P

By any chance, does anyone know what the Pokéwalker is coded in? (Most likely some sort of assembly language)

Sorry for necrobumping, but I think this is very interesting. The data structure is definitely different, but if we can get gen 5 to accept the data as Pokemon data, it might cause weird glitches which I think would be really cool.
Well ????? is a pokemon that can only be accesed by hacking the game
genrally with gameshark but the game shark code for it works in this way:
it tells the  game to make a certain pokemon appear what that pokemon is depends on the two pokemon digits in the code fore example bulabsuar code could be 4R (it isnt really) but if you put in a number for a pokemon that doesnt exist... the game wotn know what to make appear there for cusing its name sprite antacks etc to be nothing to do with real pokemon! :) :) :) hope u understood tis lol!!!

Well, I don't know how works or what use Gen V's IR port have, but anyways ; it might be possible to send Pokémon via CGB homebrew.
I'm holding back because if the transfer rate is faster than what the CGB is capable of, then... lolnope

Not sure if there's documentation on the IR protocol.
