Pokémon Red and Blue's Safari Zone (pret/pokered)

In the Safari Zone the wild Pokémon never attacks. Every battle on the Safari Zone's maps is a Safari battle, whose menu offers BALL×, BAIT, THROW ROCK, and RUN in place of the usual commands. After each of the player's actions that doesn't end the battle, the Pokémon either flees or the menu comes back; no move is ever chosen for either side. pokered-safari/turn

Bait 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. pokered-safari/catch-rate

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. pokered-safari/eating-angry

A 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). pokered-safari/flee

A Safari Ball catches exactly as an Ultra Ball does: its first roll is redrawn until it is at most 150, its HP check uses a ball factor of 12, and a missed throw counts its shakes against 150. Each throw takes one of the Safari Balls the gate hands out instead of a ball from the bag. pokered-safari/safari-ball

A Safari Zone encounter ends in one of four ways: a catch; the Pokémon fleeing; the player choosing RUN, which in the Safari Zone always gets away ("Got away safely!"); or a missed throw with the last Safari Ball, after which the PA announces "Ding-dong! You are out of SAFARI BALLs!" and the battle ends before the flee check. pokered-safari/encounter-end

A Safari Game costs ¥500 and gives 30 Safari Balls and a step counter that starts at 502, shown out of 500. Each step takes one off, and a step that finds the counter at 0 ends the game ("PA: Ding-dong! Time's up!"); running out of Safari Balls ends it as soon as the player is back on the map. Either way the PA says "Your SAFARI GAME is over!" and the player is sent back to the gate. pokered-safari/game
