Hey, Lukas!
Welcome to PC!
Don't worry about the language barrier. :) PC has members from all around the world.
It seems like you're very interested in emulation like Wind Heart said, so you might want to check out the magnificent things you cna find in the
emulation forum. As you probably already know, PC is very known for its ROM hacking community. There are some awesome player-made hacks out there for you to challenge. xD
I hope you enjoy yourself here!
