Is it possible that the latest Switch model can still work using PKHeX? I have no idea what you mean by 1012+, I assume it's the update file or model number? Why is it so difficult to hack now? Is Nintendo against this practice? If I have the latest Switch model, how do I supposed to hack my Let's Go, Pikachu game?? I'm out of luck? I remember Codejunkies provided us Action Replay which let us hack the old games like X and Y and Sun and Moon without any complications. I didn't have to worry about what 3DS model I had, I just needed the game cartridge and away I went. It was so simple and user-friendly compared to using PKHeX. :/
