And look at how much of a success Nintendo was at that too.
In europe they did quite a good job against ds cards.
TC thinks Nintendo can just sue TX and this will disappear but really it won't, it will make matters even worse for Nintendo
Suing TX won't make it worse for them, it will just cost them lawyer and court fees. But unless TX has broken a law in their home country then it will be the importers who are targeted. They have been willing to try that in the past.
this is why Microsoft allows homebrew onto Xbox One X and such, they have realised it's better to reach out than to completely fight hackers head on over and over and I know Xbox One is hard to hack but who needs to hack it when you can use homebrew and retroarch on it without hacking it.
That side steps the issue, but it's something that Sony did on the PS1 & PS2 for a high price before doing it for free on the PS3 and instantly regretting it. While Nintendo have never tried it.
Where we are today is that Nintendo don't allow that, they are now faced with a hack that allows piracy and they have to do something about it. Bending over and taking it is unlikely to be their first response.
