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)
So far I like the gameplay and use of the touchscreen. I had tried black version and didn’t like it as much somehow. This one has the feel of the original, same grid design same map. But wit 3D graphics on top (kinda like the Zelda remake for Switch)
