Airtime 0.9.1
=============

A voxel racing game inspired by Super Skidmarks.

Starting the DOS version
------------------------
Keep airtime.exe, cwsdpmi.exe and the complete data and res folders
together. Game definitions are data\cars.dat and data\terrain.dat. Change to that folder and run AIRTIME.EXE.

The target machine is a Pentium MMX with 64 MB RAM, a VESA video card and
Sound Blaster-compatible audio. The normal display is 320x240. Run with
--nosound if no supported sound card is available.

Menus and racing
----------------
Use Up/Down to choose a menu entry and Enter to select it.
Escape returns from a submenu; Escape on the main menu exits to DOS.
Single Player offers Tournament, Challenge and Practice.

The keys here are the defaults. Options > Controls sets the keys for driving,
Select and Back: choose a row and press the new key. A key taken from
another row leaves that row with none, and Delete clears a row; Restore
Defaults puts every key back. Select always has a key, and Escape always goes
back, whatever Back is set to. The keys are saved in config.ini (key-steer-left=a and so on), where the
menus' cursor keys can be set too (key-menu-up, key-page-down and so on).

Left/Right steers, Up accelerates, and Down brakes or reverses.
After finishing, Enter leaves the race. Escape during a race goes back to
the menu. F8 changes to the next song. F7 restarts the current song,
or goes to the previous song within the first five seconds.
F1 shows the controls and F4 toggles the information display.
Debug keys are Shift and an F key, on without --debug; Shift+F1 lists them.
Shift+F5 switches between the original skid and an experimental layered
skid. The original skid is the default; --skid=new starts with the new sound.
Hold Shift+F2 for one-tenth speed in menus, replays, transitions and local
races. Races using it do not rank. Music and network races keep their normal
speed. Shift+F3 shows each AI car's skill over its roof, Shift+F4 the regions
uploaded to the screen. Shift+F7 and Shift+F8 make the cars smaller and
bigger, Shift+F9 jumps, and Shift+F10 on the splash or menu goes straight
into a race. F12+X quits at once.

Score Board lists saved results. Extras contains About, Replays, the
built-in Benchmark, Changes and component Licenses.
Up/Down scrolls Changes and Licenses; Page Up/Down jumps to the ends.
Advanced Options has Title Replay: On plays recorded races behind menus;
Off uses the splash picture. The setting takes effect immediately.
Replays use Space to pause/resume and Left/Right to seek. Escape leaves
playback. Multi Player requires an IPX network.

Saves and recordings
--------------------
Scores and race recordings are written below the game's folder by default.
To keep them elsewhere, set AIRTIME_SAVE before starting, for example:

  SET AIRTIME_SAVE=C:\AIRSAVE
  AIRTIME.EXE

Keep the save folder writable. Completed recordings appear in the replay
browser. Autopilot, debug and automated harness races do not rank.

Useful startup options
----------------------
  --nosound       Run without sound.
  --highres       Use 640x480 instead of 320x240.
  --no-record     Disable race recordings.
  --help          Show the full command-line help.

Debug controls and automated benchmark options are for development;
ordinary play does not require them.
