* The Adlib music does not sound right. I'm speculating that we would need to use the SAMPLE.* files from the original for Adlib instruments. Here is a description of the format probably used by SAMPLE.BNK:  http://www.descent2.com/ddn/specs/bnk/ . The adlib.diff patch could possibly provide a starting point.

== Game issues ==
* The following (minor) bugs were found in a Discworld 1 playthrough on 2012-05-27. It is suspected, but unconfirmed that they occur in the original interpreter. If so, they should be moved to [[Tinsel/Bugs]].
** Act 2: After the first trip through L-Space to the library in the past, the game can get stuck when the "Hiding From Thief" script is triggered and Rincewind hides. This appears to be caused by a problem with the Luggage pathfinding to hide and getting stuck. As the mouse is disabled at this point and the game is waiting for the Luggage to hide before the Thief appears, the game is stuck. This only seems to occur when playing the game from a clean new game start to this point i.e. during release playtesting, but it is recoverable as exiting and loading a savegame from just before this does not exhibit the bug and allows the game to continue.
** Act 2: The scene outside of the Hideout waiting for the Thief to give the password can glitch badly if the glass is used on the pipe very early. This causes a bad GFX glitch with Ego (Rincewind) jumping to the top left of the screen and then walking down-right until back to normal. This is not game-breaking.
** Acts 1-3: (Seen in Act 3) At the Livery Stable, the drunk Donkey's "hiccup" bubbles are in the top left of the screen, rather than correctly located over the Donkey's head. Unsure if the original exhibits this.
** Act 4: Loading Mambo/M16 with coals, only the coughing animation is shown each time, except for the last time when he "roars" and smokes. Though this act's scripts are known to be buggy, IIRC the original interpreter shows an animation of Rincewind pouring the coals into M16 prior to coughing animations...
** Act 2-4: In the Dark Wood (heading to Nanny Ogg's cottage), there are two trees on the path with a large spider web between. On the first walk, Ego (Rincewind) triggers a "Walking into Spiderweb" animation, and the web is no longer visible on latter visits. However, either on any latter visit or after load, though the web is not visible, the "Walking into Spiderweb" animation plays when Ego walks through this point. This probably occurs in the original.
** Act 3-4: Pathfinding on the drive at Lady Ramkin's Dragon Sancturary is buggy and can result in Ego (Rincewind) walking through the closed gate/gatepost. This probably occurs in the original.
* Add fixes/workarounds for bugs present in the original games - See [[Tinsel/Bugs]].
* Currently, we semi-arbitrarily assigned F5 & F7 to open the load/save dialogs (dreammaster did this to match Lure, which in turn follows the 'Sierra standard'). Maybe we should agree on some standard hotkeys which work in all (most/many) engines?


* Perform play testing, look for problems, and then add them all here!
== Discworld 1 Mac (demo / full) TODO ==
* The scene where Rincewind finds the dragon's loot at the end of act 1 is severely bugged. Rincewind and the dragon's treasure constantly disappear and reappear, and Rincewind's animations constantly restart (e.g. the animation where he enters the scene, the animation where he stuffs the treasure into the trunk and so on). I do not remember this bug from earlier revisions, perhaps it is a regression from the latest ProcessSleep removals?
* Some stray black pixels are shown in some sprites (palette glitch, or an issue with our graphics function implementation)
** Update: The buggy animation is directly related to the subtitles speed. If the subtitles speed slider is moved all the way to the left (fast subtitles/no delay), the scene is shown correctly.
** Subtitle speed seems to cause other glitches much earlier in the game, e.g. at the very beginning, when Rincewind gets out of his bed. (These, or at least something similar, happen in the original interpreter)
* The Rincewind looking out screen saver sequence can occur during the credits, after the ending sequence. When that sequence is stopped (via mouse click), the credits fail to resume. (this doesn't happen in the original interpreter)
* After finishing the game, after the ending animation and the credits screen, we are taken back to the title screen (where it says "Press any key to start"). If the game is started again, its state has not been reset so all the actors are in the state they were in act 3/4 - i.e. the luggage is awake, the dean is missing, the sleazy guy in prison and so on. (this happens in the original interpreter)
* When you ask the Lecturer of Recent Runes (in the Dining Room) about the librarian, the subtitles say "No, no, no." while the voice-over says "Did you get the number of that donkey cart?" It is probably the sample that is wrong, not the script, since the sample IDs are played in order. (Only in English V2?) (this happens in the original interpreter)
* When examining the trapdoor in the broken drum, its description ("Hmmmm... that characteristic scent of turpentine, crushed cockroaches and recycled beer!") does not fit on screen. (this happens in the original interpreter)
* After opening/closing the Luggage's inventory, the frame around Rincewind's inventory is sometimes drawn wrong. I've only seen this happen after learning how to pick pockets. You can try [http://www.update.uu.se/~d91tan/ScummVM/dw.004 this savegame], for English v2. (this happens in the original interpreter)
 
== Other stuff ==
 
* (medium) Add support for both the v1 and v2, and maybe even the demo. The opcode list may require tweaking. Various ways come to mind, for example, do it like in the ScummEngine (instead of one big switch/case for opcode dispatching, use a table with member funcs, and then have multiple such tables, one for each game version).
* Right now, we semi-arbitrarily assigned F5 & F7 to open the load/save dialogs (dreammaster did that to match Lure, which in turn follows the 'Sierra standard'). I (Fingolfin) would prefer if we could agree on some standard hotkeys which work in all (most/many) engines...

  • The following (minor) bugs were found in a Discworld 1 playthrough on 2012-05-27. It is suspected, but unconfirmed that they occur in the original interpreter. If so, they should be moved to Tinsel/Bugs.
