Port fixes, each found by playing the levels with the stick:

• Walls (0x80066014): the ground step is tested at three points ahead of the body, its reach past the step straight on and its half width to each side, at a step's height. A wall there turns the whole step along whichever axis is open, at the full speed (the slides 0x80061a64 / 0x80061b28); a ledge low enough to climb is left to the climb. Before, the step was a point test and a step into a wall was undone, so a run along a wall at an angle stuck. Oracle runs (running_into_a_wall_ slides_as_the_original, spike_stops_short_of_a_wall_as_the_original): Tommy at 45 degrees into the hub's wall at x 12288, either side, holds x 11924 and slides 170 a frame; straight at it he stops at 12020; Spike in level 11 stops 479 short at 200 a frame. The reach both ways is the hierarchy box's x half width (header +4/+0xc: Tommy 250, Spike 315); the box's z (Spike's 1000) is not it, though 0x80066014 reads +8/+0x10 for the reach.
• In the air across a place with no floor record: only the across part is undone and the fall goes on (0x8005f1b4 moves across, then down). The whole step was undone, so the body could hang in the air for ever (level 12's stairs, level 3's aisles).
• The jump's first air step (in the root-key code) met no wall, so a jump taken beside a wall put the body inside it, where it could never land.
• Mirrorland's balloons were in the world from the start, so one taken before its box was opened never counted and its colour could not be finished; they now wait out of the world until the box places them (0x8007ccb4 takes them out of the loader's lists).
• Game::hide drops the object's boxes from this frame's lists at once; Game::bodies keeps every box the player met this frame.

Tests: walk_to plans the way (Ground: cheapest-first over 256 cells, steps, climbs, hops onto tops, running jumps along the body's own jump_shape, the body's width against the COL, doors, things and characters as they stand, a 1024 grid of the boxes) and plays it with the stick, Square, R1 and Cross, planning again where a move failed in play (banned) and using a shut door it comes to. With levels_walked (ignored, by hand) every put and enter_room walks. Level tests changed to play as a player would: level 3 takes the balloon; level 6 carries five boxes up the steps; level 10 races the babies on Chuckie's floor first and plays on after a lost race; level 11 eats the bones with running jumps through them; level 4 follows Cynthia to her newest spot; Mirrorland collects nearest first; face and the aims are the stick's. The campaign test plays every cinematic it came to (36, 15952 frames) to its end.
