MODERN HEART AND SOUL 1.2.1m2 IS AN UNOFFICIAL MODDED VERSION OF HEART AND SOUL 1.2.1

DO NOT REPORT BUGS FROM SAVE MIGRATIONS

1.2.1m2 officially supports HnS 1.2.1 saves (m1 DID NOT). It should work out of the box and should have little to no issues (but might).

1.2.1m1 saves might exhibit Pokédex issues. If any Pokémon caught is not showing up, catch it again. They will also exhibit Challenges issues, with options set to on or off even if they weren't before. Use the debug menu to reset your challenges to what they were before.

The official recommendation is to start a new game in 1.2.1m2 if you come from 1.2.1m1. That's the catch of having compatibility with 1.2.1.

ADDITIONS

• Gorebyss is now Water/Psychic and has been buffed (same BST), and it has Rain Dish as its second ability (Optional, only if using "Pokémon types" set to Modern).
• Added Calm Mind, Light Screen, Reflect and Skill Swap to Gorebyss TM movepool (Optional, only if using "PokémonMovepool" set to Modern)
• Huntail is now Water/Dark and has been buffed (same BST), and it has Drizzle as its second ability (Optional, only if using "Pokémon types" set to Modern).
• Added Taunt, Torment, and Thief to Huntail's TM movepool and added Dark Pulse and Pursuit to its level-up learnset (Optional, only if using "PokémonMovepool" set to Modern)
• Added "Move" to the "Item" submenu in the Summary screen

IMPROVEMENTS

• Updated FRLG Sprites
• FRLG-ized overworld sprites that were taken from Emerald (obtained from ChromusSama, eeveeexpo.com)
• Added Brick Break to Delibird's moveset
• Added missing TM/HM learnsets for Pokémon like Sunflora that have their type changed via Pokémon Types (applies with “Pkm moveset” set to Modern. “Pkm types” does not control TM/HMs. You should not mix and match these options, but that’s up to the player)
• The 3 og Regis have Clear Body unless "Pokémon Stats" is set to on, which adds (not swaps) Clear Body with other abilities. This lets users choose if they prefer the Regis with Clear body or their other ability while catching them.
• Deoxys forms now have Pressure unless "Legendary abilities" is set to on, which swaps Pressure for other abilities except the Normal form.
• Spinda 2% double damage and Groudon's Fire-Type stab only happen with "Pokémon stats" set to Modern
• You can't trade if you have a Pokémon with an HnS Pokéball, and you can't put Pokémon in HnS Pokéballs via the bag. You will need to fix that Pokémon before trading using the NPC available at the Trade Center in Ecruteak. Unfixed species will remain a bad egg in other games than HnS.
• The Trade Fixer NPC now lets you select a Pokémon to fix and doesn't fix your entire party at once.
• Prof. Birch intro Pokémon is randomized between 4 species: Azurill, Wynaut, Budew and Lotad
• Prof. Birch intro is now paced better: your name is asked after the gender, then the difficulty, and then challenges
• Berries DON'T count for the 4 item limit in Hard Mode anymore
• Certain held items and Pokémon species give you a trade warning
