I recently used PKHeX to change my Trainer name (an 8 year old me could only manage AAAAAA), with great success, even changing the OT name for all party pokemon and stored pokemon.
Unfortunately 8 year old me also named my rival AAAAA which i would like to change, it does not look like I can do this with PKHeX so I downloaded HxD with the hope that someone could point me in the right direction on how to do this? TIA.
