>>31754828iirc I only tried the one address. Not super good at Cheatengine though so the other anon might have more luck.
I'm in postgame anyway and I liked cyndaquil/riolu so I didn't really need a starter change.
For the other anon Citra should be able to use any JKSM save files generated by anons like according to this:
https://github.com/citra-emu/citra/wiki/Dumping-Save-Data-from-a-3DS-Consoleunless Project Pokemon comes up with a save file editor which would shortcut most of that.
The gateshark cheat codes are here:

It requires an old version of Citra to use the cheat codes since the modern Bleeding Edge builds remove the capability. I think Citra Bleeding Edge 83 should have the cheats.
Super Mystery Dungeons takes a fuckload of patience to run on Citra at 5 FPS on long cutscenes because you have to disable the HW renderer or crash. The dungeon ingame runs at about 120 FPS for me though with zero crashes, as smooth as silk.
I think the experience is much better on a 3DS or hacked 3DS all things considered.
