The DMCA will still have effect for example, if the modder is in Germany and hosts their cracks on Github. A DMCA takedown can be sent to Github to take down the crack. The modder should be untouchable by American authorities (directly).
If the crack is hosted in a (for example) Swedish server, then the DMCA is no valid (only at the server owner discretion).
DMCA doesn't forbid you to crack the console, but to release the tools to circumvent a security measure. You can brag all what you want on internet about a crack you've made, but the moment you publish even a clue on how to crack something, a DMCA can be sent to either put down the info from a website or to make you to desist (only if either you and/or the server are located, or have business, in the United States).

Edit: modder is a 26 years old male living in Belgium (https://twitter.com/forestillusion/status/134123063191354163...)
Might apply, might not apply here. IANAL and I have not read the article :)
Edit: America to USA. However, Americans (as in people from the US) should note that there are similar provisions throughout Americas (especially Mexico and Brazil).
