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 play on my Android phone and I honestly love being able to just install the APK once, or even just install the emulator from like the Play store.
Pokemon is like the perfect game to play on phones though, HG/SS is my fav Pokemon game in the series and it has a bunch of cool custom ROM versions too. Pokemon games just play so well on phones.
I just hate how you can't easily trade from game to game to actually "collect em' all"
The emulators I've tried made it very difficult
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?
