Scenario File Options

The Project Apollo scenarios have a vast number of options that you can specify. Some of the more useful are:

General options

These are options specifying things such as the fuel mass, the intended orbit after launch, etc.

Option	Function
TOAPO	Specifies the desired launch apogee altitude in kilometers.
TOPER	Specifies the desired launch perigee altitude in kilometers.
TOHDG	Specifies the desired launch azimuth in degrees.
DLS	Set to 1 to delete the launch site when the spacecraft passes out of visible range. This can give a significant performance boost on slow machines.
FDAIDISABLED	Set to 1 to disable the OpenGL FDAI rendering. This can give a significant performance boost on slow machines.
IGMST	Inertial Guidance Mode start: set to the time in seconds after launch at which the autopilot switches to inertial guidance mode and starts trying to hit the target orbit rather than follow the pre-planned pitch program.
SIFUELMASS	Specifies the mass in kilograms of the fuel in the first stage (SIc or SIb).
SIEMPTYMASS	Specifies the empty mass in kilograms of the first stage (SIc or SIb).
SIIFUELMASS	Specifies the mass in kilograms of the fuel in the second stage (SIVb for Saturn 1b or SII for Saturn V). This is not used for the INT-20.
SIIEMPTYMASS	Specifies the empty mass in kilograms of the second stage (SIVb for Saturn 1b or SII for Saturn V). This is not used for the INT-20.
S4FUELMASS	Specifies the mass in kilograms of the fuel in the SIVb stage of Saturn V and derivatives.
S4PL	Specifies the payload of the SIVb stage. Current values are: 0 Standard LEM 1 ASTP 2 LTA LEM test article 3 LM1 test LEM 4 LTA8 LEM test article 5 Docking target 6 LTA6 LEM test article 7 Empty 8 Docking adapter for an SIVb 'wet workshop'
AUTOSLOW	Set to 1 to slow to 1x time acceleration when 'something important' happens. For manned flights, this is typically when a piece of mission audio is played, for unmanned flights it is typically a stage separation, engine burn, etc.

AGC options

AGC options are specified between AGC_BEGIN and AGC_END. Options outside those lines will be ignored.

Option	Function
YAAGC	Set to 1 to use the Virtual AGC rather than the C++ AGC
EMEM	Set an AGC erasable memory location to a specified value. Addresses and values are both specified in octal (base-8), so to set address 10 (decimal) to 17 (decimal) you would specify EMEM0012 21. In general you should use LMPAD and CMPAD instead of specifying specific memory locations as both C++ AGC and Virtual AGC use the same scenario values to store different data.
