Capture

1. ^ abAt full HP a Great Ball can catch more often than an Ultra Ball (computed): against a Bulbasaur (catch rate 45) with max HP 100 and no status, the Great Ball catches about 11.4% of the time and the Ultra Ball about 10.2%. A throw rolls two random numbers from 0 to 255, and on both a low roll is the one that catches. With no status, the first roll must be at or below the species' catch rate, its base-stats byte, which loading the opposing Pokémon copies in; the Great Ball rerolls any first roll above 200 and the Ultra Ball any above 150, so the Ultra Ball's first roll passes at least as often. The second roll must be at or below a target of max HP × 255, divided by 8 for the Great Ball or 12 for the Ultra Ball, then by a quarter of current HP (at least 1); a target above 255 catches with no second roll. The Great Ball's smaller divisor gives it the larger target, and with no status and a catch rate of 200 or more both first rolls always pass, so there the Great Ball never catches less often.Codepret/pokeredrevised

2. ^ abcdeA sleeping or frozen Pokémon is easiest to catch, then a burned, paralyzed, or poisoned one. The ball subtracts 25 from its first number for sleep or freeze, 12 for any other status, and nothing without one, and a first number below that amount catches at once: sleep alone catches on 25 of a Poké Ball's 256 first numbers (9.8%) and on 25 of an Ultra Ball's 151 (16.6%) (computed). Otherwise the throw fails when the first number less that amount is above the catch rate, and goes on to the HP test when it isn't.Codepret/pokered

3. ^ abcdefgThe lower the Pokémon's HP, the likelier a throw that passes the catch-rate test (the first number, less the status amount, at most the catch rate) is to catch, and a Great Ball's second test is easier than any other ball's. The ball computes $T=\lfloor \lfloor 255M/F\rfloor /\max (\lfloor H/4\rfloor ,1)\rfloor$ from the Pokémon's max HP $M$ and current HP $H$, with $F$ 8 for a Great Ball and 12 for every other ball, each division rounding down. A $T$ over 255 catches; otherwise a second random byte catches when it is at most $T$. At full HP the second test so passes about a third of the time (about half with a Great Ball), and from roughly a third of max HP down (half with a Great Ball) it always passes (computed).Codepret/pokeredrevised

10. ^Across all 151 species, a species' catch rate runs from 3 (Articuno, Zapdos, Moltres, and Mewtwo) to 255 (fifteen species, among them Caterpie, Pidgey, Rattata, and Magikarp), and its base HP from 10 (Diglett) to 250 (Chansey). The species' names are as the game prints them.Codepret/pokeredrevised

11. ^ abA failed throw's shakes depend only on the ball and on the Pokémon's catch rate, HP, and status, so every failed throw of one ball at a Pokémon in the same state shows the same count: no random number feeds it (computed). The game computes $Y=\lfloor 100C/B\rfloor$ from the catch rate $C$, with $B$ 255 for a Poké Ball, 200 for a Great Ball, and 150 for any other, then $Z=\lfloor \min (T,255)\cdot Y/255\rfloor$ from the HP test's result $T$, plus 10 for sleep or freeze or 5 for another status. A $Z$ under 10 misses ("You missed the POKéMON!"), under 30 shows one shake ("Darn! The POKéMON broke free!"), under 70 two ("Aww! It appeared to be caught!"), and 70 or more three ("Shoot! It was so close too!"). The code's branch for a $Y$ over 255, which would show three, never runs: $Y$ is at most 170 (computed).Codepret/pokered

A species not yet owned is first registered in the Pokédex and its entry shown ("New POKéDEX data will be added for …!").

13. ^A wild Pokémon enters battle at full HP with no status. Its max HP is $\lfloor 2(B+D)L/100\rfloor +L+10$, capped at 999, where $B$ is its species' base HP, $L$ its level, and $D$ its HP DV, with no stat-experience bonus. A DV is a hidden value from 0 to 15 that each Pokémon has for each stat. A wild Pokémon's attack, defense, speed, and special DVs are the four 4-bit halves of two random bytes drawn when the battle loads it, and its HP DV takes the lowest bit of each: 8 from attack, 4 from defense, 2 from speed, and 1 from special. A level 5 Bulbasaur (base HP 45) so has 19 to 21 max HP (computed). A trainer's Pokémon gets fixed DVs and keeps its party HP and status instead, and a transformed one keeps the DVs it had before transforming.Codepret/pokeredrevised

17. ^ abBait makes a Pokémon harder to catch and a rock easier. Bait halves its catch rate, rounded down, and a rock doubles it, up to 255; each throw works on the rate the last one left, so a Chansey's 30 becomes 15 after bait and 60 after a rock. Halving has no floor: six baits take a catch rate of 45 to 0 (computed), and with no status a rate of 0 still passes the catch-rate test, in which the ball's first random number, less the status amount, must not be above the catch rate, when that first number is 0. When the angry count runs out, the rate returns to the species' own value, undoing every bait and rock before it. When the eating count runs out, the rate stays where the bait left it, and bait thrown at an angry Pokémon clears the angry count without resetting the rate, as a rock thrown at an eating one clears the eating count.Codepret/pokeredrevised

18. ^Bait makes the Pokémon eat and a rock makes it angry, each for 1 to 5 more turns, and each ends the other: bait clears the angry count and a rock the eating count. The turns added are a random byte's low three bits, redrawn until under 5, plus 1, and a count stops at 255. After each of the player's actions that doesn't end the battle, the game prints "Wild CHANSEY is eating!" (with the Pokémon's name) and takes a turn off the eating count; when the Pokémon isn't eating, it prints "Wild CHANSEY is angry!" and takes one off the angry count, and with neither count it prints nothing.Codepret/pokered

19. ^ abA Safari Pokémon flees more often the faster it is, much less often while eating, and more often while angry: at a speed of 50 it flees about 39% of the time (100 in 256), 9.8% while eating, and 78% while angry (computed). After each of the player's actions that doesn't end the battle, it flees ("Wild CHANSEY ran!") when a random byte is below a threshold $b$, so with chance $b/256$. $b$ starts at twice its speed (the speed's low byte, all of any speed under 256), and a low byte of 128 or more makes it flee at once. While it is eating, $b$ is divided by 4, rounded down; while it is angry, $b$ is doubled, up to 255. The count is taken off before the roll, so bait that adds $n$ eating turns lowers the chance on $n-1$ of them (computed).Codepret/pokeredrevised

20. ^Yellow's catch formula is Red and Blue's: every range, status value, ball factor, shake divisor, and shake threshold quoted here is the same in both. The cases around it differ. Yellow adds the Pikachu battle in Pallet Town at the start of the game, which shows Professor Oak on the player's side: a ball there takes the old man's branch and catches outright, and, as in the old man's battle, the full-party-and-box refusal is skipped and the Pokémon isn't given to the player. In the old man's battle itself, the throw catches outright unless a story flag for the first catch training is set, in which case it skips the catch and takes the three-shake result, $63, the value a failed throw's shake count of 70 or more gets. After every catch it gives the player, Yellow also sets Pikachu's mood.Codepret/pokeyellow · pret/pokeredrevised

22. ^Except with a Level Ball, PokeBallEffect scales the ball-modified rate $C^{\prime }$ by HP: $X=\max (\lfloor C^{\prime }(3M-2H)/3M\rfloor ,1)$ for max HP $M$ and current HP $H$. When $3M$ is 256 or more, both $3M$ and $2H$ are first divided by 4 (a quartered $2H$ of 0 becomes 1) and only each low byte is kept, so the formula breaks for max HP over 341.Codepret/pokecrystal

23. ^Crystal adds 10 to $X$ for a sleeping or frozen Pokémon, capped at 255, and nothing for burn, poison, or paralysis: the test meant to add 5 for them reads a value the sleep-and-freeze mask has already cleared. Gold and Silver have the same code, and their disassembly notes that those three statuses were meant to rank between sleep and none.Codepret/pokecrystal · pret/pokegold

24. ^The final rate goes into wFinalCatchRate, and one random byte at most that rate catches, so the chance is $(X+1)/256$ and a final rate of 255 always catches. This one roll decides the throw; the wobbles come after.Codepret/pokecrystal

25. ^The ball's wobbles are drawn after the throw is decided. A caught Pokémon always gets three. On a failed throw, each of up to three wobbles happens with chance $p/256$, where $p$ is read from the first row of WobbleProbabilities whose catch rate is at least the final rate (63 for a rate of 1, up to 255 for 255). The table's comment gives nLeft/255 = (nRight/255) ** 4, so each $p$ is a fourth root, $p/255={(\mathrm{𝑟𝑎𝑡𝑒}/255)}^{1/4}$.Codepret/pokecrystalrevised

26. ^An $a$ over 254 catches at once.
