Now that Tempest Elite is available for Sale and being shipped. We decided to make this a technical support thread. Tempest Elite is set up to by default to run on a stock Atari XL/XE computer with 64K RAM with standard 6502. We are not taking responsibilities for program conflicts caused from custom hardware upgrades other than VBXE or Stereo Pokey. Makes use of the RAM under ROM ($C000 to $CFFF & $F800 to $FFFF). Does not make use of extended RAM over 64K, like 130XE, RAMBO, etc. Does not take advantage of any 65816 upgrades or issues undocumented (illegal) 6502 instructions.
On Startup Tempest Elite checks for VBXE present in the $D640 or $D740 memory areas, if not detected, it will continue to load the standard Atari graphics and Player/Missile multiplexer sections into RAM. If detected, a VBXE blitter is loaded into RAM instead. The VBXE can be bypassed by holding down option key when the cartridge when turning the power on.
Stereo Pokey is checked in the $D210 memory area. Majority of the 2nd Pokey Chip upgrades use this area. I am aware of some custom upgrades that placed the 2nd pokey at $D280, or Quad Poker, or with COVOX chip. Tempest Elite does not support Pokey chips mapped between $D220 to $D2FF.
"CONTROLLER" + "JOY+UP" or "CONTROLLER" + "JOY+DOWN" is for joystick and the direction you need to press for the "super zapper." If your joystick works with standard Atari Games, it will work with Tempest Elite. Tempest Elite does not support extra fire buttons. When the title splash title is on your screen. You can use the joystick to choose game options or use the console SELECT & OPTION buttons. However the joystick will only select "JOY+UP" or "JOY+DOWN." to choose other controllers, you will need to use the OPTION button to choose these other controllers. Space Bar or Escape Key toggles the pause. When using alternate controllers, Space Bar triggers the "super zapper" and only the Escape Key toggles the pause. Paddle Controller option moves the ship depending on how far the paddle knob is turned.
Trackball controller is based on CX-80 and WICO Command Trackball based on that 2bit code. Some of these have "joystick mode" also. Some people managed to hook up an Atari ST track ball that uses "gray code", which may work with the (Indy 500) Driving Controller option. If a trackball or driving controller is causing the game options to cycle through a rotation on the title splash screen, move the controller until it stops, or unplug the controller and plug it back in.
