If anyone has managed to get into http://www.warioworld.com and become a member because I can't jon because they need to phone you to see if your a developer, just asking around to see if anyone has managed to get into it, most likly not but still, worth asking, its also worth taking a look at the site, if you have'nt seen it before.
Well, u can get SDKs from there But why u wanna join? If u only wanna SDKs, u dont need account. Just whois their server, then scan ports, and find what programs they have, then search vulnerabilities on those programs, then go to their databases, and dl what u want Legit way u cant get in, except if u are a serious developer =D
