- following statements to set the display up -
-
- SIMCGA 5 I *
- MEDRES *
- DIGGER *

- 3. SPACEWAR will run with the following patch - it does not affect operation

-
- SIMCGA I *

- 4. BATTLEZONE will run on DOS 2 without changes - DOS 3.1 or later needs
- patches to work in either SIMCGA or normal CGA mode. The problem is
- with DOS 3.X interrupt support for networks.
-
- If you want to run BATTLEZONE under DOS 3.1, try the following patch -
-
- DEBUG BZONE.COM *
- -F106 LE BF 20 00 E8 18 00 BF 24 00 E8 12 00 EB 3C *
- -F124 L10 50 1E 06 31 C0 8E C0 FA 26 C5 1D 81 7F f8 00 F0 *
- -F134 L11 75 0A C5 5F F6 26 89 1D 26 8C 5D 02 FB 07 1F 58 C3 *
- -W *
- Writing 300 Bytes
- -Q *
-
- To run, do this -
-
- SIMCGA I 3 S *
- ...press Return to reboot DOS... *
- BZONE *
-
- This approach may be used with any game that loads itself over DOS.
- The "S" parameter allows SIMCGA to relocate itself at the top of
- your machine's memory - out of the way of DOS and your game.
