It's silly, all the legal precedence we have for emulators were for commercial offerings. If Nintendo wants to hit you with so many invalid lawsuits that you're forced to fold then this certainly won't stop them.
It's just bullying and it's going to keep happening until there's laws in place protecting it.
Some of the best inventions in history came from people reverse engineering the work of others. If we want to keep moving forward then we can't let companies bully people out of innovating. It's shooting ourselves in the foot.
This was always an impressive emulator - it was originally made for the Open Pandora (an ARM-based mini-computer not much bigger than a DS). It's always been free for that - it's just, you know, you'd have to own an Open Pandora (I do!)
I am always amazed at its official forum. The dev has tight control over it, each post need to be approved by him in order to post, there are many threads that are years old on the front page mainly due to the fact that the dev didn't approve new response.
Case in point, there was a update a while ago that moves the default save folder to another location, many user had posted threads asking solution, without any resolution, I have also faced this issue few months back and finally tracked it down, decided to post it and can't.
Huh, is this why it was suddenly ported to the Miyoo Mini on the new OnionOS version? Was very surprised when I saw it because I thought it was closed source.
Bought this a couple of months ago myself that said its probably a good thing it's being open sourced I just have bad timing and bad luck in general when I buy things of the play store.
Just as an example I bought GTA Vice City and a few weeks later my phone updated to 14 and it hasn't loaded or even seen an update since. So yeah avoid that one.
