Theron’s Original Movement Commands

Authentic Source

Capture work/theron-forward-command-complete-v1 comes from the US edition’s authentic Track 02 (MD5 ceb02343868f80cec899e9b239aff2da), System Card 3.0 (MD5 ff1a674273fe3540ccef576376407d1d) and save state f17f377df210b4a3ae904a13fb85a7f0. Input is right@1:140,down@2:33,i@145:5; no generated game data is used.

Button I at internal click coordinate $8A/$8F queues command type $03. The trace contains exactly 65,536 ordered main-RAM writes. Its MD5 is cae8749574e4668c62b71b131fe62e74; the authentic 64 KiB code window’s MD5 is 77d2253b4aed117847d8d1d685506ca0.

Original Movement and Position Chain

Queue dispatch at $D3B0..$D3CB sends command types $03..$06 to $CD87. For the captured $03 event, the routine reads the current position from $40/$41, calculates the destination cell and passes the approved move’s destination $03/$03 through $45/$46.

The persistent position commit occurs at $C1FA:

tii $20B4,$2040,$0002

The write trace records both destination changes at logical PC $C203 and physical PC $0DC203. The starting position is $40/$41 = $02/$03; after the commit it is $03/$03. The RAM image before the command has MD5 86f7cec0a943402daae0ec0acdf7a372, and the image after the queue is cleared by $2905=$00 has MD5 eae73a9991630a6fe2bcc48c2c99861c.

Backward and Side Commands

Three additional captures from the same authentic starting state complete the panel’s four movement commands:

• $98/$A5 queues $04, sidestep right.
• $8A/$A5 queues $05, backward.
• $7B/$A5 queues $06, sidestep left.

The original routine calculates movement direction as (command type - 3 + $3F) & 3, where $3F is the facing direction. $05 commits position $02/$03 → $01/$03 through the same $C1FA path; the command trace MD5 is 0488166dec2eaec19b8874b01f7f1fba.

From this starting state, both side cells are blocked. The $04 and $06 traces therefore have no writes to $2040/$2041; instead, the command queue is cleared at $CC41. The trace MD5s are 009168a72f01bf4e8bb6095195c880cf and ff097d6bdd2345e21ca40baa6e3fa489, respectively.

Production Boundary

Firestaff maps $03..$06 to the same relative directions and uses the actual Track 02 cells and objects in the already loaded Theron world for traversal. Backward and side steps preserve the facing direction. The captures prove successful forward and backward movement as well as the original’s blocked side path; further special cells remain subject to their own existing real-data gates.
