Hi!
I've been trying to get a shiny cyndaquil in heartgold using the pokemonrng website, a modded new 3DS with alt settings and a real European HeartGold cartridge
I thought I was using the right setup as I got a shiny chikorita in about 15mn but I've been trying for an hour with cyndaquil and it just doesn't shine
I've gotten what looks like the right timing with zero offset, the right nature but not shiny
I know the screenshot isn't very descriptive but that's the only one I took
