Poke Transporter GB is a homebrew app for the GBA that serves to bridge the gap between the old and new games, providing a way to pull Pokemon from the Game Boy and Game Boy Color titles into the third generation. This is done using a custom Multiboot GBA ROM that genuinely could be mistaken for official software for just how professional and polished the final version actually is. With the ROM loaded on one system, you insert the GBA game you want the Pokemon to travel to. On another system, you put the Pokemon you want to transport into your current box, and talk to the Cable Club attendant to initialise a trade. It’s here where the magic really happens, with work behind the scenes happening to remove the Pokemon entirely from their original games. That’s not where it ends though, with a custom event being injected into your GBA cartridge to redeem these Pokemon. You can see the full process in action below:

​

Pokemon transferred in this way are modified in order to be legal in future games, though there are some quirks that mean they won’t be considered legal until they arrive in a certain generation. You can find a table detailing this here. For those interested in how it works, the creator also put together a video discussing the development process and exactly what's happening behind the curtain.

​

The application has had beta releases since December of last year, and got its 1.0.0 release just last week. If you’re interested in trying it for yourself, you can find the GitHub repo linked below.

Just a heads up. Don’t use the 1.0.0 release with Pokemon gold

There’s a major bug that will just straight delete your save data currently

 

[Darth Meteos]

This is so awesome

Now if someone can figure out how I can get my official Mew from my copy of Pokemon Stadium that would be epic.

My original Red GB game save is lost. But my official mew is on my Pokemon Stadium cart on n64

Looks so clean! Was just wondering, like, one hour ago, if somehow transferring from 2G to 3G was possible now thanks to homebrew. Did you read my mind?

I’m pretty sure this same person made a program for that as well

They have a YouTube channel so I recall them posting something but it could be a WiP

You imagine though if someone tried to transfer a Pokémon from Red/Blue to any Pokémon game from Gen IV onward?

Like, one of those that never appeared in Scarlet/Violet? That would be insane.

According to the GitHub project description, Poke Transfer GB already supports both Gen 1 and 2 games as source, and Gen 3 games as destination. But my crystal save disappeared long ago when the battery died so I have nothing left to transfer :/

 

[chrisrlink]

yay more legallity checks incoming

 

[gnmmarechal]

Pretty neat app!

 

[PrincessLillie]

Seriously impressive. I love how clean this program feels, and I especially love the reuse of the official Fennel character.

 

[Mayo1990]

Pretty useful.... shame all my gen 1 carts have a dry battery

 

[raxadian]

This is neat but my GBC Pokemon games are dead because the battery died and the Gameboy ones probably lost their saves because it has been like... over two decades.

So is too late for me to get any use from this.

Pokémon Cancel? What game izzat?

Sorry to be "that" guy, but Pokémon data differs a lot from gen 1-2 to gen 3 and above. All this program is doing is making up data according to the kind of Pokémon you're giving it. If you have a perfect gen 2 Pokémon it will never be as perfect as it was there, because that would mean getting the full 255 EVs in every stat, something impossible in later generations. It's still a nice tool though.

 

[Kwyjor]

I was thinking they might be using the magic mode-switching single system thing, but this is fine too. (Or is that what they're actually using?)

It's been possible some time now through save data manipulation with pkhex (and PKSM, I think?) - but of course you have to dump and restore your save data to use that.

Presumably they use the same "official" magic formulas that Nintendo decided upon when using Pokemon Bank with the Gen 1-2 games on the 3DS VC.

Also some other guy reverse engineered the event system in the 3rd gen so Pokemon generated by custom events are legal. Pretty sure this guy is doing the same.

I completely forgot about those vc games hahahaha I stand corrected.

I'm actually in a similar situation! I believe it is possible. I remember there was a program which could recover pokemons from the Hall of Fame data of the n64 cart. I don't know if it included all of the original data, or had to randomize some values (like IVs?).

I never got around to building/getting a hardware tool for dumping the save from my cartridge and now I can't even find the program any more. I'm pretty sure it was on github. I will update this post if I find it.

 

[Something whatever]

Ok thats awesome
