OMEGA RACE & OMEGA RACE ARCADE for the Tandy Color Computer 3
by Claude, with assistance by James Diffendaffer
==============================================================

What is in this zip
-------------------
  OMEGABTH.DSK    Disk image with three files:
                    MENU.BAS     menu: pick a version, shows how to play
                    CLASSIC.BIN  OMEGA RACE (classic version)
                    ARCADE.BIN   OMEGA RACE ARCADE
  omegamenu.bat   Starts XRoar (Windows) with the disk and runs the menu
  README.txt      This file

What omegamenu.bat expects
--------------------------
1. XRoar, the CoCo emulator (https://www.6809.org.uk/xroar/).
   The batch file runs it from:

       D:\Downloads\XROAR\xroar.exe

   If yours is somewhere else, open omegamenu.bat in a text editor and
   change the "set XROAR=" line near the top to the full path of your
   xroar.exe.

2. The CoCo 3 ROMs, which are not included.  Put them in a folder named
   "roms" in the same folder as omegamenu.bat:

       roms\coco3.rom     CoCo 3 BASIC ROM, 32 KB
       roms\disk11.rom    Disk Extended Color BASIC 1.1 ROM, 8 KB

   Use ROM images from your own machine.  If XRoar reports a missing
   ROM, xroar-menu-log.txt (written next to the batch file) says which
   name it looked for.

3. OMEGABTH.DSK in the same folder as omegamenu.bat.

What it does
------------
  - Copies OMEGABTH.DSK to OBRUN.DSK and runs from the copy, because
    XRoar writes a disk image back when it closes.  OMEGABTH.DSK itself
    is never changed.
  - Starts XRoar as a 512K CoCo 3 with an RGB monitor and a Hitachi 6309
    CPU (the games detect the 6309 and use its native mode; they also
    run on a standard 6809).
  - Types RUN"MENU" at the BASIC prompt.  Press 1 for the classic
    version or 2 for the arcade version.
  - XRoar's messages go to xroar-menu-log.txt.

Without the batch file
----------------------
On a real CoCo 3, or in any emulator: put the disk in drive 0 and type

    RUN"MENU"

or start a version directly with  LOADM"CLASSIC":EXEC
or LOADM"ARCADE":EXEC .  The games need a CoCo 3 with 128K or more.

Controls
--------
  LEFT/RIGHT or Z/X   rotate        UP ARROW   thrust
  SPACE               fire          P          pause
  BREAK               quit the game
  Classic version: SPACE starts a game.
  Arcade version:  1 or 2 starts a one- or two-player game.
