This repository aims to provide a collection of newly written drivers for Sierra's Creative Interpreter that was the basis of various Point-and-Click adventures and other games by Sierra On-Line in the late 1980s and early 1990s.
These new drivers will be free and open-source software published under the GNU LGPL license.
This section lists all Video drivers that are part of this collection.
The SCI0 driver PCPLUS.DRV provides a 16-color mode with 320x200 pixels on machines with a Plantronics ColorPlus graphics card or compatible hardware.
It has the following features:
- Native 320x200 pixel 16-color mode
- Full mouse cursor support
- 8088 compatibility
Note: The level of optimization is a compromise between size and speed. Faster or smaller implementations are possible.
The SCI0 driver COL400.DRV provides a 16-color mode with 320x200 pixels on machines with a Color 400 graphics card by Sigma Designs.
It has the following features:
- Native 320x200 pixel 16-color mode
- Full mouse cursor support
- 8088 compatibility
Note: This driver is derived from PCPLUS.DRV.
The source code can be assembled with yasm or nasm, e.g. via:
yasm -o drv/PCPLUS.DRV src/pcplus.s
To install a driver, copy it to the game's directory and run INSTALL.EXE. The installer should auto-detect and list all the available drivers.
Alternatively, use a text editor of your choice to modify the relevant entry in RESOURCE.CFG, manually.
