Lunchtime of the Damned & Venegance of the Chicken

[Amrath]

Is there a way to adjust what screen mode these games are run in? As neither come with the standard AGS Win setup file.

[Gilbert]

These two games are rather old, that they're probably compiled with the DOS engine (so old that it's possible acwin.exe didn't exist at that time).
To change resolution, start the command prompt and change to the directory the game's in. Then type:

GAMENAME --setup
(where GAMENAME is the name of the game's executable file)

Note that games compiled for the DOS engine cannot be executed in windowed modes (unless you execute them with acwin.exe, read this, which may not be possible if these agmes were made prior to AGS V2.13).
