The Legend of Zelda: The Minish Cap (zeldaret/tmc, and the US ROM)

The Minish Cap counts Link's health in eighths of a heart, as A Link to the Past does and as the zladx annotators' comment on Link's Awakening's health byte says ("$08 = 1 heart"); a new file starts him at 24, three hearts. When Link holds up a Piece of Heart, the code refills his health to its maximum and adds 1 to the piece count. The fourth piece resets the count to 0 and then does what a Heart Container does: it adds 8 to the maximum, capped at 160 (20 hearts, A Link to the Past's cap), and refills his health again. Both earlier games also make a container from every fourth piece. tmc/heart-pieces

The scripted ScriptCommand_IncreaseMaxHealth (src/script.c L1499-L1502) does the same +8, cap 160, and full refill. The heart branch runs when the item-get's mode (the entity's timer) is 0, 1, or 2; mode 3 empties a bottle instead.

The Minish Cap takes a touch's effects from a collision matrix: the entry at the toucher's hit type × 34 + the touched one's hurt type. For an Octorok or a Leever (hit type 25) touching Link in his normal state (hurt type 0), the US ROM's entry gives Link 30 invincibility frames, a knockback duration of 8, and 2 damage, a quarter heart. The collision loop skips a pair while either has a nonzero iframe count, unless either has bit 7 of its collision flags set, and Link's count steps one toward 0 each frame his update runs, so the protection lasts 30 frames. Link's Awakening sets its count to 80 and A Link to the Past to 58. tmc/hurt-iframes

The iframe count is signed: a negative count (the Octorok's −1) also blocks contact and steps up toward 0. A Peahat (hit type 112) gets the same twelve bytes. Charms divide the damage, Nayru's by 4 and Farore's by 2, with a floor of 1 (collision.c L226-L235). The matrix's knockback speed is not the speed Link moves at (knockback).

While Link's knockback duration is nonzero, a routine that his normal state calls each frame counts it one step toward 0 and, if it's still nonzero, moves him 0x280 along the knockback direction; the code's walking speed kWalkSpeed is Q_8_8(1.25), 0x140, so the atlas reads the push as twice walking speed, though the move routine wasn't read. His normal state skips the code that reads the d-pad while the duration is nonzero, so the player can't steer. The collision loop stores the direction for both parties, Link's the reverse of the toucher's. Among the cancels: a jump, a dash, a roll, a fall, swimming (a swim state above 1), a held object (states 1–4), and climbing unless the push is south. After an Octorok's touch (duration 8) that's 7 moves (computed). Link's Awakening's push runs a 16-frame countdown. tmc/knockback

The 7 counts the decrement before each move: 8 to 7 moves, …, 2 to 1 moves, 1 to 0 returns. LinearMoveDirectionOLD is assembly the atlas didn't read, so the units of 0x280 are inferred from the walking-speed constant, not shown. While iframes are positive and Link isn't swimming, a Minish, or jumping, the push also puts away his items and plays the bounce animation (L1913-L1920). The matrix's knockback speed (24 × 16 for an Octorok's touch) goes to Link's knockbackSpeed field, which this routine doesn't read.

When a monster dies, its death effect calls the drop routine with the monster's drop table: 6 for Octoroks, ChuChus, Leevers, and Peahats. Unless the room disables random drops, the routine adds the table's 16 weights to an active Picolyte's row, then adds 5 to the heart weight at 8 health (one heart) or less, 3 to bombs with none carried, 3 to arrows with none, and 1 to the 5-rupee weight at 10 rupees or fewer; a weight below 0 (the tables rule an entry out with −999) counts as 0. One Random() value then picks the entry: its bits 24–27 choose where to start, and the value modulo the weights' sum walks the 16 entries from there. Table 6 weighs nothing 73, a green rupee 25, a heart 5, bombs 1, and arrows 1, so with no Picolyte and no need bonus an Octorok drops nothing about 70% of the time (computed). Bombs and arrows drop only once Link has the bag or the bow. A Link to the Past instead steps each prize pack through 8 prizes in order. tmc/drops

For a fixed start each entry covers its weight's share of the sum, so the shares are about weight / sum (73/105 nothing, 25/105 green rupee, 5/105 heart); the start and the threshold come from one random value, so the exact odds weren't computed. At one heart or less the heart's share rises to 10/110. The 5-rupee bonus can't revive table 6's −999. After all figurines a modifier row rules out shells, and after all fusions another rules out Kinstones (itemUtils.c L481-L494). Tables 24 and 25 switch rows on a low-health flag (itemUtils.c L434-L441).

Each Kinstone fuser in The Minish Cap has a data entry whose second byte, which the decompilers call its stability, is the percent chance it offers a fusion: GetFusionToOffer returns no fusion when that byte is at most Random() % 100, none before Link has the Kinstone Bag, and none before the story's progress reaches the entry's first byte. The one call the atlas read is in the Blade Brothers' first action, which sets them up. An entry of 0xFF in a fuser's list stands for a shared fusion: from a random start among 18, the first not yet fused. In the US ROM's table, of the 119 fusers after entry 0, 77 have 100, 20 have 50, 21 have 30, and one has 60 (computed). tmc/fusion-offer

The offer itself is saved per fuser (fuserOffers); the mood roll only decides whether the fuser shows it this time. Forty-seven other files call GetFusionToOffer; only the Blade Brothers' call site was read. Entry 0 is what MarkFuserDone skips (npcUtils.c L361-L364). An offer outside 1–100 becomes no fusion (common.c L1279-L1281).
