@eris@cybre.space You actually don't need that either, these days? (also a lot of these r4 card things are... fake, and barely work, and also get blocked really easily. :< - also largely impossible to get in the UK but I dunno about other countries )
Also you'll want to get a particular cart that's compatable with the 3ds firmware you have
@eris@cybre.space There are OTHER options though, such as boot9loader or something. I think I boosted a toot about it yesterday or something
