Pokémon Platinum (pret/pokeplatinum)

In Platinum the damage formula reads each move's own class (MOVE_DATA(move).class: CLASS_PHYSICAL, CLASS_SPECIAL, or CLASS_STATUS) and uses Attack against Defense for a physical move, Special Attack against Special Defense for a special one, whatever the move's type. Emerald picks the pair by type, below or above TYPE_MYSTERY in the type list, so Thunder Punch (Electric) is special in Emerald and physical in Platinum, and Shadow Ball (Ghost) is physical in Emerald and special in Platinum. pokeplatinum/physical-special-by-move

BattleSystem_CalcCriticalMulti keeps Emerald's stage table, 1 in 16, 8, 4, 3, or 2, capped at stage 4, and its sum: +2 for Focus Energy, +1 for a held item with HOLD_EFFECT_CRITRATE_UP, +2 for Chansey or Farfetch'd holding an item whose hold effect names that species, plus the move's boosts, which in Platinum come from a battle-script variable (criticalBoosts) rather than a list of move effects. It adds +1 for the ability Super Luck, which Emerald's sum doesn't read. Besides Battle Armor and Shell Armor, which an attacker with Mold Breaker ignores, Lucky Chant on the target's side blocks a critical, and so does a MOVE_EFFECT_NO_CRITICAL flag that a comment in the header says is checked but never set. Platinum draws its 16-bit roll before those tests, where Emerald draws it only after its other tests pass. pokeplatinum/critical-chance

A critical multiplies Platinum's damage by 2 after the base formula (its +2 included), at the same step as Emerald, and by 3 when the attacker has Sniper; Emerald's multiplier has no such case. As in Emerald, the critical then ignores the attacker's lowered attacking stat, the defender's raised defending stat, and Reflect or Light Screen. pokeplatinum/critical-effect

Platinum's BattleScript_CalcCatchShakes keeps Emerald's capture math: the same $a=\lfloor \lfloor Cm/10\rfloor (3M-2H)/3M\rfloor$, the same status bonuses (×2 for sleep or freeze; ×15/10 for poison, bad poison, burn, or paralysis), a catch at once when $a$ is 255 or more, and otherwise the threshold $b=\lfloor 1048560/\sqrt{\sqrt{\lfloor 16711680/a\rfloor }}\rfloor$ with up to four 16-bit rolls, each below $b$ a shake, and the Master Ball's shakes set to four after the draw. The two square roots run on the DS hardware square-root unit (CP_SetSqrt32) instead of Emerald's GBA BIOS call, and both games roll with the same generator, multiplier 1,103,515,245 and increment 24,691, keeping the top 16 bits. A Pal Park battle or the catching tutorial always catches. pokeplatinum/capture-same-math

Platinum keeps Emerald's ball multipliers in tenths (Ultra 20, Great and Safari 15, Poké 10; Net 30 against Water or Bug, Nest 40 less the level below 40 with a floor of 10, Repeat 30, Timer 10 plus the turn count up to 40) and Emerald's 10 for the Luxury and Premier Balls. Two balls have new multipliers: a Dusk Ball gives 35 at night, late at night, or on cave terrain, and a Quick Ball 40 while the battle's turn count (totalTurns) is 0. The Dive Ball's 35 now asks for water terrain (TERRAIN_WATER) where Emerald asks for an underwater map. A Safari Ball multiplies the catch rate by one of 13 fractions from 10/40 to 40/10, picked by a stage that starts at 6 (×1), where Emerald uses a Safari catch factor. The Heal and Cherish Balls, also new, give 10. pokeplatinum/capture-balls

In Platinum the ability Technician multiplies a move's power by 15/10 (rounded down) when that power is 60 or less, Struggle excepted. The test reads the power after the battle's power multiplier, Charge, and Helping Hand have changed it. pokeplatinum/technician
