You know, I've actually been far nicer than I should be. Truth be told, you haven't helped the OP nor any other OP for that matter, in fact none of the "pro-Gateway" arguments have ever helped people in this situation.
You all like to argue, "Well it works for me," that's perfectly fine that it works for you. GM9 setup as my FIRM0 and Mizuki as my CFW works fine for me, but I won't suggest it over B9S+Luma3DS. But working fine for you doesn't help the OP nor the countless other threads like this. People are making these threads because something isn't working for them and thus they turned to us to fix that problem. The issue always being, the solution is stop using Gateway and saying that always ends up in the same arguments, but never actually helping the OP. To which we simply can't help them anymore, beyond either suggesting they make a frankenfirm or stop using the cart. Those are their only two solutions left at this point and makes far more sense to just using what is causing the problem for the OP. Just because it works for a few, doesn't help the people it's no longer working for. Offering a solution that does actually help is the only thing we can do, but that also means the most helpful thing isn't something they are going to like hearing.
Stating my dogmatic nature against Gateway doesn't make me wrong, if anything that's more an ad hominem. I am very much against this cart's continue support, but I also stay to the facts and pose questions to why people really keep supporting this team. They have made 4 promises and failed to meet all of them, they even failed to meet the ETA for their new cart. It boggles my mind that there are still groups of people who see this and continue to argue against me. This isn't about "knowing limitations," the team hasn't giving a solid update in over 8 months, while only communicating with us through 3rd parties. The most solid update we got from them, was that there was going to be an update on August 10th, 2017, which came and went without an update.
Now I could easily shrug this off and in fact I have actually shrug it off before. But this case, none of you have actually helped the OP. Me suggesting Gateway users move to something else has boiled down to the most helpful suggest a Gateway user can get at this point. Tell me, "It works fine for me," while ignoring the fact that it doesn't work fine for the OP, doesn't help them. That's something I can't simply shrug off.
The other arguments of, "It's just a kid's system" or simply telling me to leave aren't helpful either. In fact that's just dismissing the issue as whole, which is the worst way to handle an issue.
