Kewl, their goal was the same they just couldn't get there after a serious try (not 15 minutes). If you can make it do ANYTHING as far as controlling the cards then you could make it "clump" the cards. That is just simple logic done in code.
I'm not going to dissect the inconsistencies in all this. I've posted far too much because it does interest me. I'm also offended because I actually believed this lie and repeated it.
You may want to gloss over the difference in a code and a password but the 2 are very very different. To a layperson you might think "code that lets you access things you otherwise couldn't". There are just so many inconsistencies here. I'm not a good writer and it takes me too long to convey my thoughts. If they had the same code as you then surely they'd been able to find these cheat modes but it just doesn't exist.
I'm saying the capability of the hardware is such that yes it could definitely be modified to do whatever. This is common sense.
I don't believe there is a magic cheat-code (much like a video game) that enables anything like you suggest. I very very strongly believe such a thing doesn't exist and nothing outside of Kewl's claims have given any credibility to such a thing existing.
You can turn an ICE car into a EV (LOL) but that doesn't mean it is done via simple switch. It takes a lot of expertise and engineering. Much like this. You have to rip out the guts of the ICE car for starters and replace it.
Your claim is analogous to the automakers putting in a switch for electric mode and then not telling anyone. (Not the best analogy)
These 2 things are vastly different.
I wouldn't dog you so hard if you weren't sticking behind your absurd story of your guy hacking it in 15 minutes. Have a discussion about shufflers - sure. Don't bring up your bullshit story again. It is offensive.
