These versions boot directly from disk, and utilise a disk based copy protection. The disks cannot be read from DOS, and the game cannot be installed to HDD. Running these original versions is problematic even with DOSBox due to the copy protection disks which are not supported.
These versions run from DOS, and utilise a disk based copy protection, typically referred to as a key-disk. The game can be installed on a HDD, but will not run unless the copy protected disk is in the drive. Running these versions is problematic even with DOSBox due to the copy protection disks which are not supported. But they can be run in ScummVM without problems.
Later releases as part of various compilations do not feature the key-disk.
This is an experimental patch for Sierra's old AGI games, to makes them play three voice music and sound effects via a Adlib or Soundblaster compatible card.
The 1987 AGI version for DOS supports the following video modes.
Note: For the above command-line options to work the AGI interpreter must be v2.4xx or later.
When running the installer (INSTALL.EXE), two graphic adapter options are offered
Regardless of the graphic adapter selected, the game will render in only 16 colours. When the IBM PS/2 option is selected, the game will technically start in a 256 colour MCGA video mode, but will emulate a 16 colour EGA display. MCGA was only supported as an integrated video adapter on the IBM PS/2 Models 25 & 30, which do not have EGA backward compatibility. However the MCGA video mode is supported on VGA adapters, so any PC with a VGA adapter can normally run either EGA or MCGA mode. DOSBox-X is the only emulator which has a special machine=mcga mode.
When running the installer (INSTALL.EXE), four music card options are offered
The Roland option requires a MPU-401 with intelligent mode. Also despite the long list of Roland options, the game is really only compatible with the so-called MT-32 Old. Running it on the MT-32 New or any of the other options will result in incorrect sounds and hanging notes.
The second option, is a pure Adlib sound option, that does not use the Sound Blaster's digital sound effects. It is best selected for sound cards that are not fully Sound Blaster compatible.
A complete and free remake of the game, it adds new VGA style graphics, dialogue, an updated Point-and-Click UI, and a complete soundtrack.
It can be found on the developer's official website.
