Battles and Moves

Battle rules

  • Physical/Special split: moves are individually Physical, Special, or Status. Their category is no longer decided by type.
  • Separate Special Attack and Special Defense replace the original single Special stat.
  • Modern critical-hit chances: about 1 in 24 normally, 1 in 8 at +1 stage, 1 in 2 at +2, and guaranteed at +3. High-critical moves add one stage; Focus Energy and Dire Hit add two.
  • Sleep lasts 1–3 turns, and PokΓ©mon can act on the turn they wake up.
  • Burn, poison, and Leech Seed deal 1/8 of maximum HP each turn instead of 1/16.
  • Enemy stat-lowering moves no longer have an extra, artificial 25% chance to fail.
  • Ultra Balls now have their own catch modifier.
  • Both sides' battle stats are capped at 1,023.

Updated type matchups:

  • Bug against Poison: half damage, previously double.
  • Poison against Bug: normal damage, previously double.
  • Ghost against Psychic: double damage, previously no effect.
  • Ice against Fire: half damage, previously normal.

These are selected updates from later games; Yellow++ does not use every rule from a single later generation.

Battle screen and controls

  • Redesigned battle HUD, including HP bars, level display, status symbols, and PokΓ© Ball graphics.
  • Colored icons show each move's type and category.
  • An effectiveness indicator helps judge the highlighted move against the opponent. Sand Attack's indicator accounts for its ability to ignore type immunity.
  • Hold LEFT in the move menu for power and accuracy; hold RIGHT for the move's effect description.
  • Press B in a wild battle to quickly select RUN.
  • Faster HP bars and smoother move-menu loading.
  • Larger trainer prize-money amounts fit in the reward display.

Updated move effects

  • Tri Attack can burn, freeze, or paralyze, with about a 10% overall chance.
  • Poison Sting and Sludge have about a 30% poisoning chance.
  • Acid, Aurora Beam, BubbleBeam, Bubble, Constrict, and Psychic have about a 10% chance for their stat-lowering effect.
  • Struggle is typeless, with recoil changed to a quarter of maximum HP instead of half the damage dealt. Opponent recoil currently uses your PokΓ©mon's maximum HP.
  • Pay Day generates money equal to five times the user's level, up from twice the level.
  • Swift no longer hits PokΓ©mon during the invulnerable turn of Dig or Fly.
  • Focus Energy, accuracy, healing, and other battle fixes are listed under Bug fixes.
