  • Battle Sim: Each battle has 1-5 random effects permanently applied, based on streak
  • Battle Factory: Rent Pokémon and swap with defeated opponents to secure victory

• 32 new move tutors were added to the Battle Frontier
• Cosplay Pikachu can be received at the Battle Frontier, with her costume being changeable
• A Masuda Ditto trade was added to the Battle Frontier
• Added a Wonder Pick feature to the Battle Frontier that lets players acquire Frontier-ready Pokemon in exchange for PokeChips. This also allows the player to get Pokemon otherwise inaccessible in the game
• Hisuian forms added to the swarm tables. Note that some are unavailable outside of Wonder Picks
  • Their moveset compatibility is taken from gen 9, due to gen 8 (Legends Arceus) being very limited for them
• The ItemFinder’s functionality was converted to a Dowsing Machine, which points to the nearest item as the player approaches it and remains on screen even after battle
• The options page is now split into 3 to make room for new options:
  • Choose between the Last Used and Optimal ball. Optimal is default

• Improvements to the player’s trainer card:
  • Now has 5 achievable star levels, with the Black Card awarded when getting all 5
  • The back of the card now shows relevant player stats
  • An NPC was added to Ascension Tower to allow the player to print their current party to the back of their trainer card

Significant Changes

• Added item data for almost every remaining item (held, form changing, mega stones, etc.). Some of these are unavailable to the player outside of Wonder Picks and hacking the items in. Notably, items to increase IVs by 1 and reset all EVs were added.
• Added the Magma Stone key item to Carnelidge Volcano, which increases egg hatching rates and pairs with abilities that do the same

• Blastoise can now learn Iron Head via TM, to support Blastoisite-G mega evolution
• Mega Sandaconda’s ability was changed from Sand Spit to Aerilate
• The ROM is now consistently sized at 32mb, which should make it flashable to physical carts (I cannot verify this unfortunately)
• Some items, such as Leftovers and Choice Items, have had price adjustments now that they’re purchaseable at the Battle Frontier
• The swarm pool was shrunk to include Hisui Pokemon, to one Pokemon per evolution line. This means each species is more likely to appear
• Any Pokemon from a swarming evolution line is now eligible for bottlecap rewards with the Swarm Swami Assistant
  • For example, Goomy gives no reward, but both Sliggoo-H and Goodra-H do, despite the latter not appearing in the swarm pool

• Updated the Divergent Mode game modifier unlock requirement to unlock after 5+ swarming species have been caught, now that players have had a chance to experience Divergent Mode fully
• When starting a new game with QoL items, the Oval, Catching, and Shiny Charms are now given

  • Fire Fang -> Flame Burst
  • Dual Wingbeat -> Pluck
  • Aura Sphere -> Vacuum Wave
• The DexNav now has heightened shiny odds at streaks 5-99 and 100+, instead of just at 50 and 100. It also now caps at 100 to communicate that players are getting the maximum benefit
• Rephrased the gen 1-8 randomization game modifier to explain the impact it has on saves (supported now, with some items unavailable through normal play)
• All level up movesets were updated to gen 8, to support Wonder Picking and randomized runs
• Updated the DexNav scan so water & cave encounters can only jump to another tile 0-2 times (40% for first, 20% for second). Grass never jumps.
• Updated the rare pickup drop table to provide better rewards
• The PokeVial is now filled when entering the Hall of Fame
• PokeChips can now be found after catching a Pokemon, in addition to when they faint
