Version differences
- Originally released in 1987 in Europe, ported by Imagine Software. Then a second port was released in late 1988 in the US, ported by NovaLogic.
1987 European edition
This version only supports CGA graphics and PC Speaker sound. This version seems to be quite rare.
1988 American edition
This version supports CGA, EGA and Tandy graphics, and PC Speaker and Tandy sound. It also adds Mouse support.
Essential improvements
1987 European version PC speaker audio support
The PC Speaker sound of the original 1987 European release is highly dependent on the speed of the PC. It was meant to run on the original IBM XT and faster machines will play sound too fast.
|
Use DOSBox
|
|
Notes
- In your DOSBox config file, in the [cpu] section set
cycles=240 to approximate the speed of an IBM XT.
|
1988 American version three-channel audio support
- The 1988 American release of the game has support for three-channel audio, which requires the audio hardware built into the Tandy 1000 computer. Other systems are limited to single-channel audio played through the PC speaker.
|
Use DOSBox
|
|
Notes
- If DOSBox is configured to emulate a Tandy computer with
machine=tandy, the game detects and uses the emulated Tandy sound hardware for three-channel audio. This will simultaneously also force the game to run in 16 colour Tandy graphics mode.
