Concept	Super Mario Bros. 1985
Coyote time	Mario gets no grace window after leaving a ledge; `ProcJumping` refuses airborne jumps unless he is swimming. T3
Gravity	Vertical motion is 8.8 fixed point; each frame, `ImposeGravity` adds speed to position, the fraction via the `YMF_Dummy` subpixel byte, then gravity to speed. T3 `MovePlayerVertically` gives `ImposeGravity` a maximum fall speed of 4 px/frame for Mario. T3 `ImposeGravity` clamps a fall of 4 px/frame or more only when the fraction byte is at least `$80`. T3
Jump	A jump starts only on the frame A goes down while Mario is grounded; `InitJS` zeroes the vertical subpixel and sets the jumping state. T3 `InitJS` picks one of five jump rows by take-off horizontal speed, stepping up at `$09`, `$10`, `$19`, and `$1C`. T3 `PlayerYSpdData` starts a jump at −4 px/frame (rows 0–2) or −5 px/frame (rows 3–4). T3 `InitMForceData` gives jump rows 0–4 a zero speed fraction, so take-off is exactly −4.00 or −5.00 px/frame. T3 The press frame already moves Mario, since `PlayerPhysicsSub` starts the jump before the state dispatch runs `JumpSwimSub` and `MovePlayerVertically`. T3 Swimming jumps use row 5 of the jump tables, or row 6 in a whirlpool. T3
Running	Horizontal speeds are 4.4 fixed point, whole pixels and sixteenths per frame; `MoveObjectHorizontally` shifts the sixteenths into the subpixel byte. T3 Mario's top ground speed is `$18` walking and `$28` running (B held). T3
Variable jump height	While a jump rises with A held, gravity is `JumpMForceData`'s `$20`, `$20`, `$1E`, `$28`, `$28` subpixels/frame² for rows 0–4. T3 After the switch, gravity is `FallMForceData`'s `$70`, `$70`, `$60`, `$90`, `$90` subpixels/frame² for rows 0–4. T3 In rows 0–1, the standing and slow jumps, held gravity is `$20`/256 = 0.125 px/frame². T3 In rows 0–1, falling gravity is `$70`/256 = 0.4375 px/frame². T3 In rows 0–1, falling gravity (`$70`) is 3.5 times held gravity (`$20`). T4 `JumpSwimSub` swaps in falling gravity, never back, once speed is zero or downward, or once A is not held both this frame and last after a `DiffToHaltJump` rise. T3 `InitJS` sets `DiffToHaltJump` to 1, so a release switches gravity only once Mario has risen at least 1 pixel. T3 Simulating the jump code on flat ground gives apexes, tapped/held, of 24/66 px standing, 27/71 px walking (row 2), and 29/83 px running (row 4). T4 Simulated with A held, Mario's jumps peak at 66 px standing, 71 px walking, and 83 px running. T4
