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:

PKMDS Update — March 18–25, 2026

New Features

• One-touch evolve — An Evolve button now appears in the Pokémon editor when the selected Pokémon can evolve. Single-path evolutions happen immediately; branching evolutions (Eevee, Slowpoke, etc.) open a picker showing each option with its sprite and method. Evolving Nincada into Ninjask will offer to place a Shedinja in your next empty box slot. Gen 2 trade evolutions now show which held item is required.

• Box pop-out dialogs — Two new buttons in the box navigation bar let you pop out the current box into its own dialog window, or open a full all-boxes grid view. The all-boxes view lets you swap adjacent boxes with a single button click.

• Generation-specific editor tab — A new “Gen-Specific” tab appears in the Pokémon editor when relevant, covering fields that only exist in certain games: Shadow Pokémon status and purification (Colosseum/XD), Shiny Leaves and walking mood (HGSS), PokéStar Studios fame (B2W2), GO Park spirit/mood and received timestamp (Let’s Go), and more.

• Pokédex: Legends Arceus research task editor — You can now open a per-species research task editor from the Pokédex tab in LA saves. Buttons to complete or clear all research for all species are also available.

• Spinda spot preview — The Pokémon editor now displays Spinda’s unique spot pattern based on its PID / EC.

• Trash bytes auto-fixer — Added a one-click trash bytes cleaner to the Legality tab for quickly resolving legality flags caused by leftover junk bytes in name fields.

• Origin mark shown in Met tab — The origin mark sprite (Pentagon, Clover, Galar mark, etc.) now also appears in the Met tab alongside the existing display in the Cosmetic tab.

Improvements

• Loading a .pk* or mystery gift file now places it into your currently selected slot (or the first empty slot if none is selected) and navigates you directly to the box view — no more hunting for where it landed.
• The Pokédex tab now has a filter to show only seen or only caught species, and the box selector dropdown shows the box count.
• The Bag tab renders noticeably faster on large saves thanks to grid virtualization.
• Bug reports submitted through the in-app report dialog now require a name and email address.

Bug Fixes

• Fixed bottom UI elements being cut off on iPad screens.
• Fixed several crash reports from Sentry (duplicate key crash, file-abort error noise, empty file load crash).
• Fixed held item autocomplete not being clearable; also prevents a crash when held item data is missing.
• Fixed pager visibility and filter button clipping in data grid views.
