How does Pokecheck work?

[Terresquall]

Hello,

I've recently gone into competitive Pokemon and started to use Pokecheck for a variety of purposes and I'm really impressed with what I saw, being a programmer myself. The thing that really blew me away was how Pokecheck could "intercept" transmissions to Nintendo WFC to receive Pokemon data. Does anyone know how its done?

Also, for the official Nintendo hack checking Pokecheck tool, does Pokecheck query a specific IP address at a certain port to get the result?

pokecheck queries pkvldtprod.nintendo.co.jp for the nintendo hack checking. as for the overall site, it's just the gts exploit that you'll see in other programs here mixed in with some other things that we worked on privately.

well, https://pkvldtprod.nintendo.co.jp/pokemon/validate

Thanks for your help. I found a couple of GTS exploit threads and I will let them take it from here

Just one more thing: for the actual hack check, do you query the HTTP port with a post request? How do they tell you whether the hack check has been valid or not?

i'm pretty sure that for the nintendo hack check, pokecheck pretends to be a game validating a pokemon and taking the result back from the validation server. how exactly we did that, i don't recall anymore because it was once about 2 years ago. we did a fair amount of disassembly, though.
