Your Own Pictures

github-actions[bot] edited this page Nov 10, 2026 · 1 revision

Everything ArcadeDMD shows is drawn by the program. No image comes from the games, apart from your LaunchBox Clear Logo when a game starts. You can swap some drawings for pictures of your own, by dropping them in the sprites\ folder of ArcadeDMD.

Your pictures stay yours. They are never in the zip of a new version, nor in the repository, and an update leaves them in place.

How a picture is used

  • PNG works everywhere. .gif, .jpg and .webp work too for the Metal Slug pictures.
  • A plain background around the drawing is made transparent and the empty margins are cut, so a picture cut out roughly is fine.
  • runtime\arcadedmd.log says which picture is used, or where one would be read from.

On the HD screen

Game Where Names
Metal Slug, all six games sprites\mslug\<name>.png vehicles tank, camel, slugnoid, flyer, copter, mariner, drill, astro, and elephant, ostrich, bradley, mobile, gunner, claw, walker, armor, seen from the side, gun to the right
Metal Slug, all six games sprites\mslug\<name>.png soldiers marco, tarma, eri, fio, trevor, nadia, a small portrait beside the soldier's name
One Metal Slug game only sprites\mslug2\<name>.png, sprites\mslug3\<name>.png... the same names, for that game alone
Windjammers sprites\wjammers\<name>.png the six players scott, costa, wessel, yoo, biaggi, mita, on the court where the game puts them

The French names (char.png, chameau.png) and the older sprites\mslug_tank_hd.png for the tank still work. See Metal Slug.

What File
The INSERT COIN screen sprites\insert_coin.gif (or .png), 128 x 32. A Pixelcade GIF, for example. It replaces the coin screen as long as there is no credit, and the coin still drops when you insert one
The little Metal Slug tank sprites\mslug_tank.gif, or a mslug_tank.png strip of 3 frames, 5 pixels high at most, cannon to the right
The runner of Sonic sprites\sonic.gif, or a sonic.png strip of 6 frames, sonic2.gif for Sonic 2. Adjust "y" in the game file to its height

The game's logo

The logo shown when a game starts is your LaunchBox Clear Logo, found by itself (see HD Marquee). A game without one gets its title in metallic lettering on the HD screen.
