- UniCGA Version 1.0: Universal CGA simulator (c) 1991 Tommy Frandsen
- -------------------------------------------------------------------------------
- CGA simulator for the Hercules Graphics Card
-
- Features:
- - Supports all CGA graphics and text modes
- - Automaticly detects the correct CGA mode
- - Four different simulation methods
- - Adjustable refresh rate
- - Has been succesfully tested with many applications and games
-
- Requirements:
- - An IBM PC/XT/AT/Clone
- - MS-DOS/PC-DOS 2.0 or higher
- - A Hercules Graphics Card/Clone
-
- Syntax: UCGA [ -c | -cxxx | -f | -s | -sxxx | -d | -u | -h ]
-
- Description:
- UCGA -c : hardware simulation, 240 refreshes/min.
- UCGA -cxxx : hardware simulation, xxx refreshes/min.
- UCGA -f : hardware simulation, no refresh (fast)
- UCGA -s : software simulation, 180 refreshes/min.
- UCGA -sxxx : software simulation, xxx refreshes/min.
- UCGA -d : software simulation, DOS controlled refresh
- UCGA -u : disable simulation and return to text mode
- UCGA -h : show help-screen
-
- Comments:
- - The "-f" option (hardware simulation without refresh) is very fast but
- produces annoying blank lines. The "-c" option (hardware simulation
- with timed refresh) is slower but eliminates the blank lines
- - The "-s" option (software simulation with timed refresh) is the slowest
- simulation method but it produces the most pleasant display
- - The "-d" option (DOS controlled refresh) will only work with programs
- that uses DOS for input and output (like COMMAND.COM)
- - Use the DOS MODE command to switch between 40 and 80 column text mode
- - Use the DOS GRAFTABL command to load graphics characters (ASCII 128-255)
-
-
- Warnings:
- - Do not run UCGA if there is no Hercules Graphics Card installed
- - Do not run UCGA if there is more than one graphics card installed
- - Although this program has been very troughfully tested, any usage of
- UCGA is totally at your own risk. I am not responsible for any damage
- caused by the program, either direct or indirect, to your hardware
- or software. If you can't accept this restriction, please don't use
- UCGA.
