CHEWY: German demo crashes looking for a non-existing det0.taf file

Cc: Game: Chewy: ESC from F5


Today's Git HEAD (d0b5a35785a01bca5d9ba0bd3bb284cb6ea72ff4) on macOS 12.4 x86-64.

The demo, as hosted by ScummVM, immediately aborts looking for a non-existing det0.taf file. Some other bug reports may look similar, but they don't mention the demo or they say that the intro works. Here, it's the (German) demo and it crashes before any intro.

Here's an LLDB backtrace with some additional debug.

comment:1 by dwatteau, 21 months ago

From Discord, it appears that the demo is just unsupported at the moment.

comment:2 by dreammaster, 21 months ago

Confirmed. There'd need to be non-trivial changes to the engine to get the demo working.

Some findings from running the game demo with DosBox:

  • First room is DET51.TAF (Film Set)
  • "Room" DET43 is a close-up talking to Howard, Det48 is the "room" inside the tent on the Film Set location, Det55 is up the ladder (from the left of Film Set, opened up after you solve the VHS/TV puzzle), Det52 is the map, Det54 is a location with a pool of piranhas, and Det53 is the Temple location (opened up after you solve the piranhas puzzle and get the diary from the hut).
  • There is a short intro cutscene which seems to be playing the file: cut/cut.tap
