Date added to ScummVM 2013-10-17
First release containing it None

The Avalanche engine was used in Lord Avalot d'Argent.

This engine was added by the GSoC student uruk to ScummVM as part of the GSoC 2013. The source code was provided by the authors, Mike, Mark and Thomas Thurman, who released it under the GNU GPL version 2 license.


A couple of missing functions in the main menu, working mini-games, completable


  • Class refactoring (WIP)
  • Control of the drop-down menu with keyboard shortcuts
  • Demo mode (If the player doesn't start playing and being idle for a certain time in the main menu, the games starts to demo itself.)
  • Some sections of the main menu
  • Intro animation (Not sure if we have the sources for that one.)
  • Outro screens (See Closing!)
  • Some Easter Egg connected to the display of scrolls
  • Sound options in-game and keeping them in sync with ScummVM's options
  • Fix Shoot 'Em Up minigame

Differences from the original

  • The ScummVM version uses a slightly different font for some of the texts in the game. (Nim, Help, ShootEmUp's instuctions, Boss key.) Maybe they'll be replaced later.

Outstanding original bugs

  • The original game doesn't update the little icon which represents the direction Avalot is facing if you control him with the mouse by clicking on the background. At the moment, this bug is also present in the ScummVM version of the game.
  • After you rescued Geida and leave the screen in front of the Baron's castle to the right, Robin Hood won't come to take the girl away. You have to go back to the screen to trigger the event. There's a missing 'also line', which causes the bug.

Fixed original bugs

  • There was a bug in the original engine that caused the internal timers of the game to mess up when a savegame is loaded. The problem was that when you loaded a savegame, the engine set the internal timers for the room by default and after that loaded the timers you saved when you saved the game. For example in the first room, if you made a save while Avvy was sleeping and loaded it back, you may have noticed that his wife, Arkata's timer was messed up: she shouted every time she should counted from the time you saved, and shouted every time the room's newly set internal timer told her to do so. Now it is fixed: if you load a savegame, the engine only loads the saved timer, and leave the default one for the cases when you enter a room newly.
  • The original game didn't load properly the state of Avvy's speed (walking/running) from a savegame: The little yellow dot at the bottom of the toolbar was always set to "walk" state, even if at the moment of the saving Avalot was currently running. In the ScummVM version, this bug is fixed.
  • In the original, when you play the harp in the abbey, the game doesn't always hide the mouse cursor. In the ScummVM version, it works properly.
  • The spiderweb on the ghostroom scene was misplaced in the original (it wasn't exactly at the right corner of the screen). Now it's fixed.
