I installed Ignited via SideStore. No Jailbreaking necessary. Not computer tether. SideStore can renew the side loaded emulator every 7 days when on WiFi. The iPhone is perfect for DS emulation with a stylus.
(Ignited is a fork of Delta with more options, and SideStore is a fork of AltStore, with no computer tether needed)
I’d rather play it on the 3DS, but it’s cool that you enjoy it your way :)
If I had a 3DS. Also I have my phone with me at all time.
