Read this:
The only parts I want to add that wasn’t mentioned here is that someone leaked the ROMs online, but without the memory card dump as well as solving the NR reader issue, it will be unusable to those who download them. (Also remember piracy isn’t allowed here).
I’ve been seeing that people (those who do engage in the piracy on other platforms) would try to give it a crack, and would then proceed to give up on it. So far, it doesn’t appear emulators want to implement fixing the NR reader issue, as I’m told that seems to infringe on Nintendo copyright.
I can’t source the exact thread or post, but I vaguely remember reading that the original plan was to somehow have it physically accessible to the public, and that was negatively affected by the leak and thus put on hold.
At the very least, the stuff is all preserved safely. Not much more to say really.
And finally, remember that asking for ROMs are piracy and not allowed here.
