Super Mario RPG's data tables (Yoshifanatic's Super Mario RPG disassembly)

A character reaches level 2 at 16 experience in all, level 10 at 700, level 20 at 3950 and level 30 at 9999, where experience stops: a character already at 9999 gets none, and a total past it is cut back to 9999. After a battle, unless a flag that skips the award is set, each party member gets the battle's experience whole, doubled for one wearing the Exp. Booster, and goes up every level the new total reaches, several at once if it reaches several. super-mario-rpg-tables/experience-to-level

The flag 0x0B64 is set by a routine that clears it and sets it when the value at 0x48 is 0xFFFF; what that value is, and when the routine runs, is not read here. The comparison at level 30 reads the two bytes after the table, the first bytes of the level-up gains table (12805), which 9999 never reaches, so level 30 is the last. Equip slots: 12 weapon, 13 armor, 14 accessory (kinds 0, 1 and 2 in the item table).

Each level from 2 to 30 raises a character's maximum HP, Attack, Defense, Magic Attack and Magic Defense by fixed amounts from a table by character and level, after a press of A and before the bonus the player picks (super-mario-rpg/level-up-bonus). HP is refilled to the new maximum, and the other stats stop at 255. Mario's gains climb from 5 HP, 3 Attack, 2 Defense, 2 Magic Attack and 2 Magic Defense at level 2 to 10, 6, 4, 5 and 3 at level 20, then fall to 2 of each from level 21; every character's gains fall at level 21. super-mario-rpg-tables/level-up-gains

Toadstool's rows are zeros up to level 9, Bowser's to 8, Geno's to 6 and Mallow's at level 2. From level 21 Mario, Toadstool and Mallow gain 2 of each, Bowser 4 HP and 2 of the rest, Geno 1 HP, 3 Defense and 2 of the rest.

Mario learns Fire Orb at level 3, Super Jump at 6, Super Flame at 10, Ultra Jump at 14 and Ultra Flame at 18; Toadstool Sleepy Time at 11, Come Back at 13, Mute at 15 and Psych Bomb at 18; Bowser Poison Gas at 12, Crusher at 15 and Bowser Crush at 18; Geno Geno Boost at 8, Geno Whirl at 11, Geno Blast at 14 and Geno Flash at 17; Mallow HP Rain at 3, Psychopath at 6, Shocker at 10, Snowy at 14 and Star Rain at 18. No level after 18 teaches a spell. super-mario-rpg-tables/spells-by-level

Each of the 40 entries of the weapon timing table gives four frame counts that bound a timed hit (super-mario-rpg/timed-hit): outer start, inner start, inner end, outer end. The inner window, where one press doubles the damage, is 7 frames wide for every weapon (items 5 to 35) but the Drill Claw, whose 16 to 24 is 9 (widths computed); the earliest inner start is the War Fan's frame 2 and the latest frame 50, for the Chomp, the Chomp Shell and the Spiked Link. The entries are indexed by item number. When the weapon slot is empty the entry is chosen by another byte of the battler's record; entries 0 to 4 sit on the numbers the item list names Weapon, Armor, Accessory and Space, and entries 36 to 39 on Spare, Shirt, Pants and Thick Shirt. super-mario-rpg-tables/weapon-timing

The monster table gives each of 256 monster numbers its HP, Attack, Defense, Magic Attack and Magic Defense, and the battle names it from a list of 13-letter names by the same number; 17 numbers have a blank name. HP runs up to 8000 (Smithy), Attack to 250 (Smithy and Culex), Defense to 200 (the Wind Crystal), Magic Attack to 130 (the Fire Crystal and Smithy) and Magic Defense to 180 (the Mad Adder). Each number points to 16 bytes, which the battle copies into the monster's battle record: the first two are its HP, which it starts the battle with, and bytes 3 to 6 fill the places where a party member's record holds Attack, Defense, Magic Attack and Magic Defense. super-mario-rpg-tables/monsters

The other bytes (2 and 7 to 15) are not read here; byte 2 fills the place after the party's maximum HP. Several numbers share a name, Smithy's among them, which looks like the forms of one fight (not read in the battle code).

At a battle's end, each monster knocked out in it adds the experience and coins of its row in the rewards table. The experience total is divided by the number of party members (3 at most), rounded up, and each gets that share (super-mario-rpg-tables/experience-to-level). A battle gives at most one item: going through the knocked-out monsters in slot order, the first whose roll succeeds gives it. A monster whose two item places hold the same item always gives it; otherwise a draw from 0 to 100 below 5 gives its rare item, and failing that, or with no rare item, a draw below 25 gives its common item (5 and 25 of the draw's 101 values, computed). The item goes to the first empty place of the 30-place bag, or is lost when the bag is full. Of the 239 named monsters, Culex gives the most experience (600) and Chester and Valentina the most coins (200); 107 can drop an item, and 10 hold the same item in both places. super-mario-rpg-tables/battle-rewards

About: Super Mario RPG Item drop table

Each weapon, armor and accessory adds fixed amounts, possibly negative, to five stats while worn: Speed (the stat the battle sorts its battlers by, highest first), Attack, Defense, Magic Attack and Magic Defense. It may also nullify or resist elements, guard against statuses, and give boosts from the start of each battle, and one flag per character (Mario, Toadstool, Bowser, Geno and Mallow) says who can wear it. Weapons give only Attack and a variance (super-mario-rpg/damage-formula); the Lazy Shell and the Frying Pan give the most Attack, 90, with variances of 40 and 20. The Lazy Shell armor gives the most Defense and Magic Defense, 127, and takes 50 from Speed, Attack and Magic Attack. Every character can wear the Work Pants, the Super Suit, the Lazy Shell armor and all accessories but four: the Jump Shoes, the Attack Scarf and the Coin Trick are Mario's alone and the B~tub Ring is Toadstool's. The Super Suit, the Lazy Shell armor and the Safety Ring nullify all four elements, and the Amulet and the B~tub Ring resist them. super-mario-rpg-tables/equipment

Each of the 27 specials has a fixed FP cost, power, hit rate, element and statuses. Jump costs 3 FP at power 25 and Ultra Flame 14 at 60; Bowser Crush and Geno Flash cost the most, 16, and Psychopath the least, 1. A damaging special's damage is the caster's Magic Attack plus its power against Magic Defense (super-mario-rpg/damage-formula). Sleepy Time and Mute have a hit rate of 99 and Terrorize and Poison Gas 90; the rest have 100. Jump, Super Jump and Ultra Jump carry the Jump element, Fire Orb, Super Flame and Ultra Flame Fire, Thunderbolt and Shocker Thunder, and Snowy Ice. The list of the acting character's specials halves each cost, rounded up, while the Scrooge Ring is worn, and marks a special unusable when its cost is more than the battle's FP; the cost as listed comes off that FP when the special is picked. super-mario-rpg-tables/specials

A monster has a Speed (the battle's turn-sort stat), an evade and a magic evade (super-mario-rpg/hit-chance), elements it nullifies and is weak to (super-mario-rpg/damage-elements), and statuses it is immune to. Of the 239 named monsters, Formless has the highest evade, 100, and the Jester and Mukumuku the highest magic evade, 80; 53 are weak to Fire, 42 to Thunder, 39 to Ice and 30 to Jump, and 74 are immune to all four statuses the specials inflict. The element columns read the four element bits; the low four bits of the two element bytes are not read here. super-mario-rpg-tables/monster-defenses
