Zak McDrucken — SAM Coupé 512 KB
2026 by Outsoftware using ChatGPT & Codex

Original: Denis Grachev / RetroSouls Team. Music: Oleg Nikitin.
SAM port with original loading artwork and graphics, original unpacker,
original font bitmap data, and music/effects adapted to the SAA1099.

START
Insert Zak_McDrucken_SAM.mgt in drive 1 and cold boot the SAM with normal
SAM ROM/DOS and 512 KB. AUTO starts from disk. SPACE skips loader pauses
and music; wait for the presentation and press SPACE to start the game.
In SimCoupe select 512 KB and normal 100% speed.

CONTROLS
O left, P right, Q climb up, A climb down, SPACE pick up/drop, R restart
the room. Carry the chickens to the exit using ladders and passages.

EDITABLE BASIC
Before machine-code takeover, BREAK stops BASIC (ESC in SimCoupe).
LIST displays the program. To leave its pager press BREAK, then SPACE
to activate the editor; enter 2 REM sam, press Enter and use LIST.
Leave the pager with BREAK and SPACE, then RUN reloads the disk.
After game takeover, cold boot again to return to BASIC.

VALIDATION AND AUDIO
Cold native boot, the first puzzle and entry into LEVEL02 were verified
with keyboard input only. BREAK/LIST/a real line 2 edit/RUN/reload passed.
Original music samples use a four-level SAA DAC; timbre is adapted and
the measured opening segment lasts about 4.29% longer than the Spectrum
reference. Original effects use the same DAC adaptation. All 20 room data
and the ending dispatch were checked in CPU fixtures; this is separate
from playing the whole campaign. Full campaign and physical SAM hardware
have not been tested. Supported target: SAM Coupé 512 KB.
