Happy Pokémon day everyone! I've added legality checks and fixes to PKMDS. Give it a try!

Thank you so much for this tool, it is extremely user friendly and useful.

My question may be a bit dumb regarding IV editing:

If IVs are increased in this tool, will they retroactively apply and increase stat values? For example, if the IV for HP is increased, will this then reflect in a higher HP value for an existing Pokemon? Sorry for my ignorance, I am new to save file editing in general.

Yes, of course. It should in fact happen in real time - watch for your max HP to increase / decrease as you adjust the IVs for the Pokémon. Bear in mind, the stat formula means small adjustments will be more noticeable at higher levels.

I suggest you do a bit of reading / watching videos to learn how stats work before you mess around:
