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 wish there was an updated homebrew app similar to pokemon bank. Or maybe something for retroachievements. What if retroachievements had a .jpeg cloud save that kept track of progress?
