Bugs, glitches and ToDo's

Script bugs

  • Bargon Attack: Graphical glitch when loading a save made on the Bargon bridge after transforming self (the original actor appears as well).
  • Fascination: Some versions have incorrect timing in several places as they used loading time. Fixing the scripts is required in those cases (before entering the lab was the most visible example) - Now fixed in Amiga and Atari versions
  • Fascination: The game sometimes hangs in the parking lot when the card is used directly, without the code. - This also occurs in the original exe
  • Gobliins 2: Leaving Vivalzart's screen and returning after putting the mushroom into the machine yields another mushroom in the inventory. Letting Winkle use that one with the machine locks him up.
  • Gobliins 2: In music land, trying to switch the screen should be prohibited by the scripts, but isn't. A workaround keeps ScummVM from crashing and shows a dialog box instead. [Bug #3155]
  • Gobliins 2: In the bubble screen, the game lets you try to release the prince before acquiring the safety pin, leaving you in an unfinishable state. [Bug #3392]
  • Goblins 3: 'A Bell' button hotspot disappears. [Bug #3805]
  • Goblins 3: Chessboard scene reloads after the rat is first used. [Bug #3986]
  • Goblins 3: Unable to enter the Battlefield. [Bug #4022]
  • Goblins 3: Unable to progress through queen's throne room. [Bug #4016]
  • Lost in Time: sprite gets corrupted during a dialogue. [Bug #3839]
  • Woodruff: Infinite hypnotic CDs. [Bug #3750]
  • Woodruff: Access to the Laboratory. [Bug #3751]
  • Woodruff: Wrong code for safe in temple. [Bug #3777]
  • Woodruff: Bluxtre nut not drawn after leaving it on the ground. [Bug #3742]


  • Mouse cursor sometimes shown when it shouldn't and vice versa. (Introduced when I changed cursor handling to the CursorManager; my solution isn't all that great, apparently.)
  • The number of used jokers isn't saved correctly: you'll always have 5 to spend again after loading. This is a result of using individual files for each save slot and letting the user exit with CTRL-Q (the number of jokers is saved globally for the whole game and only when exiting using the menu).


  • A few graphical glitches remain:
    • Goblins 3: double sprite glitch in the queen level [Bug #3401]
    • Lost in Time: sprite gets corrupted during a dialogue [Bug #3839]
    • Lost in Time: palette issue with sprites [Bug #3838]
    • Woodruff: Palette glitch [Bug #3768] (Also happens in the original)
    • Woodruff: Graphic glitches [Bug #3848] (2 of 3 also happens in the original)
    • Woodruff: GFX Glitches [Bug #4491] (Also happens in the original)


  • Ween: Wrong speaker sound when putting away items on some machines.
  • Fascination: The duration of short sounds is sometimes incorrect. The most obvious problem is the sound of the keys of the phone: the sound is not played for each key (first room). This may be similar to the Ween sound issue.

Engine-specific tasks

  • Add OBC Support (OBC is the new Script system which used in DEV7)

File-specific tasks


  • Add support for other rendering modes (EGA/CGA/Hercules) lega.gdr, l360.gdr, lcga.gdr.


  • Gobliiins Mac: musmac1.adl isn't played correctly at all.


  • implement loading of various Picture formats (JPEG,BMP,BRC)

Game-specific tasks

Adi 2

  • Add missing opcodes.
  • Add support for Applications.

Adi 4

  • Add missing opcodes.
  • Add support for Applications. (Geographie kind of works, compared to the main Environment itself)

Adibou 1

  • Implement workaround for German CD version, so that the user can use both Applications 4-6 Years and 6-7 Years. [Bug #14553]
    • Potential solution: if BOUALL.ITK exists from example from 4-6 Years and you have to copy the 6-7 Years BOUALL.ITK as BOUALL67.ITK, and then if only BOUALL.ITK is found use 4-6 only and if both are found open an Dialog window from ScummVM, which let you choice the the Application you want to play.
    • Current Workaround: ScummVM's detection is aware of these two versions, so you can one directory and copy both CD contents into one Folder and you can choice between 4-6 Years and 6-7 Years from the ScummVM Launcher.

Adibou 2

  • Add Printer support
  • Add Microphone support
  • Add support for the other Applications (Music, Sciences, English)


  • Add support to the RAC file, which is used by the protection of the CD version. (not really required, the game works with extracted STKs)

Inca 2

  • The (hard-coded) space shooter isn't yet implemented.
  • A few graphic glitches remain.

Little Red Riding Hood

  • Handle direction keys, so that the arcade part is playable


  • Creation tool is not working properly.
  • Clicking on a word should spell it, not the first word of the sentence

The Last Dynasty

  • Space shooter is hard-coded there, too.
  • The game currently loops strangely, thanks to the faked shooter return code.
  • Make the Segmented VMD resources working

Urban Runner

  • When mousing over the register in the hotel action sequence, the inventory pops up.
  • Corrupt encoded frames in videos are skipped or masked by original interpreter. Need to do the same.
    • Most of these are now detected and corrected masked, but three cases still remain as of 2011-04-26:
      • < 1sec white glitch in video triggered when Max approaches Door in Basement ("mxport2").
      • ~1sec white glitch in video as Adda escapes from warehouse.
      • Large red/orange glitch in Inspector Van Dell video shown after Max complete Pool Hall entry ("sn6").
