I tried on cartridge first, but that didn't seem to yield results so I switched to emulator. I got the same results either way.
No, there is only 1 shiny frame. The only thing that is different to the spread is the pokemon, it doesn't match the encounter slot. I've caught pokemon on other frames of the same seed as well, and the IVs and nature always match up, but the pokemon doesn't. Is it possible that RNG Reporter is wrong?
