DOOM on the arcade cabinet

The arcade cabinet in your lab can run DOOM, the 1993 one, from a game file on your own PC. The game never ships the file: you download it, you link it, the cabinet plays it.

The file

DOOM keeps its levels, sounds and art in a WAD file. The cabinet needs an IWAD, a whole game. The one to use is the free shareware episode id Software released in 1995, Knee-Deep in the Dead, nine levels. It may be passed around unmodified, so here it is:

Save it somewhere you can find again. If you own DOOM, The Ultimate DOOM, DOOM II or Final Doom, their WAD file works too; the cabinet names the game it finds.

In the game

1. Fit the RA-4 Multi-Game Motherboard. The vendor sells it on the ARCADE shelf; it arrives as a crate. Switch the cabinet off (tap it, POWER) and fit it under INSIDE THE CABINET.
2. Fit the Doom Uplink Module. Same shelf, same way. It only goes in once the RA-4 is there.
3. Link your DOOM file. Tap the cabinet, find DOOM, press LINK YOUR DOOM FILE and pick the file you downloaded. It is read in your browser and kept there; nothing is uploaded.
4. Power on, drop a quarter. INSERT COIN · DOOM, like any other game on the cabinet.

Controls

W and S move, A and D strafe, the arrow keys turn, the mouse turns and its left button fires, Space fires, E opens doors, Shift runs. No Ctrl or Alt: a browser keeps those for itself. Esc opens DOOM's own menu, as it always did. Quit Game in that menu, then Y, leaves the cabinet; WALK AWAY under the screen does the same at once.

DOOM on the cabinet is played for its own sake: no scores, medals or Chips come from it. The engine is Chocolate Doom, free software under the GPL; its licence ships beside it.
