However, if you want to start the game in a different graphics mode, you can do so by adding a few extra characters (called arguments) to the start command. The program does not automatically detect CMS Boards or the Covox Speech Thing. You need to instruct the game with an argument to use these cards. EXAMPLE: Let's say you want to load the game with EGA graphics mode and music generated with a CMS Board (you must have a CMS board installed). You'd type YEAGER EGA CMS and press Enter. The order of the extra arguments doesn't matter as long as there's a space between each argument. These are the arguments you can use: CGA Loads game with CGA graphics. EGA Loads game with EGA graphics. MCGA Loads game with MCGA graphics (Same graphics as VGA, but slower. Maintains compability with PS/2 25 and 30). TGA Loads game with Tandy graphics. VGA Loads game with VGA graphics. SLOWCARD When you are in MCGA or VGA mode, if the game freezes on startup, or if you get sound but the wrong colors or no colors at all, try this parameter. It slows down the interface between the computer and the video card. FASTCARD Deactivates Slowcard. JOYSTICK Loads game with joystick flight control. KEYBOARD Loads game with keyboard flight control. MOUSE Loads game with mouse flight control. MOUSE2 Loads game with high-resolution mouse flight control. LOW Loads game in low graphics detail mode (less detail speeds up game play). MEDIUM Loads game in medium graphics detail mode (less detail speeds up game play). HIGH Loads game in high graphics detail mode. NOSOUND Loads game with sound turned off. NOSPEECH Loads game with digitized speech turned off. It also reduces the amount of disk swapping necessary when playing on four 360K floppies. PC Loads game with PC internal speaker sounds. ADLIB Loads game with AdLib sound card sounds. BLASTER Loads game with Sound Blaster sound card sounds. TANDY Loads game with Tandy 1000 sound. TANDYDAC Loads game in Tandy 1000 models equipped with DAC (such as the Tandy 1000 TL),which results in clearer digitized speech. COVOX1 Loads game with loud speech driver for the Covox Speech Thing on parallel port 1. Note: there is no auto-detect for Covox so this parameter is required if you want to use Covox. COVOX2 Loads game with loud speech driver for the Covox Speech Thing on parallel port 2. Note: there is no auto-detect for Covox, so this parameter is required if you want to use Covox. CMS Loads sound driver for CMS music board. Note: there is no speech driver for CMS, so digitized speech will play through the PC's internal speaker. Also, there is no auto-detect for CMS, so this parameter is required if you want to use your CMS Board. SMALL Use this if you have a computer with less than 640K of memory. It deletes complex versions of some shapes to speed up the simulation. LARGE Deactivates Small. ALL If you want to be able to play all missions without having to win each one, type this parameter to make all missions available immediately. This is a default parameter. CAMPAIGN Starts new campaign. In order to advanced in Campaign Mode, you will need to land safely at your home base after successfully completing each mission. Note: when you quit the game, the program automatically remembers all of that game's startup parameters, as well as all the items checked on the drop-down menus. The next time you start the game, just type YEAGER and press Enter, and those same parameters and menu items will be in effect. Also, if you quit the game in the middle of a Campaign, and you want to retum to where you left off, be sure not to select the Campaign parameter the next time you start up the game, as that will put you at the beginning of a new campaign. ........................................... : KEYBOARD PROCEDURES FOR NON MOUSE USERS : Tab Moves cursor arrow sequentially through option "buttons." Spacebar Selects option beneath cursor arrow. Enter Selects option with >"text"< (arrows) on either side. Note: this may be different than the button the cursor arrow points to, so you can hit Enter to save time. Esc Exit to previous screen. Backspace Backup one screen when creating a custom mission. "Hot keys" Most options can be selected by pressing the first letter of the first word. For example, "Test Flight" is selected from the main menu by pressing T. Note: On the Historical Mission Selection screen, pressing 1, 2, or 3 will select the first, second, or third mission visible on the screen. ......................................... : YEAGER AIR COMBAT-KEYBOARD REFERENCES : VIEWS F1 Forward F2 Back F3 Left F4 Right F5 Up (Look up at 45 degrees from forward view) F6 Down (Look down at 45 degrees from forward view) F7 Plane to target F8 Target to plane F9 Map (in playback screen, this activates the "3D box view") F10 Fly-by Shift-F1 Behind your airplane, looking forward Shift-F2 In front of your airplane, looking back Shift-F3 Alongside the right wing of your airplane Shift-F4 Alongside the left wing of your airplane Shift-F5 From below looking up at underside of your airplane Shift-F6 From above looking down at the top side of your airplane Shfft-F7 Target's cockpit Shift-F8 Following target Shfft-F9 Circling external view of airplane Shift-F10 Following missile (Cursor Arrows) Slew view angle.
