The argument about xci loading only being used for piracy is probably mostly true but not in all cases, so for those edge cases we really need one for atmosphere :ph34r:
This is what I could find about the game sharing thing you are mentioning, seems like its still possible, but with some caveats.
Also from what i've read the mod chip chip does require soldering, and is not for beginners. Maybe you could find a temper in your area who is willing to do it.
You could go for an unpatched model from ebay and softmod that, or you could attempt to hardmod a new model. mod chips are still for sale on aliexpress if you search "hwfly"
