Here is a little review of supported PCX filenames in FLY.EXE 3.29d

NOTE: All graphical files must be in the "exact" 256 Colour palette as is designed with
an FST colour editor. Currently you can only get this palette by doing a screen grab with old 256 colour supporting version of FLY.EXE (ver. 3.25d was the last and is included) Note this ver.
also requires ALLEG40.DLL, not ALLEG42.DLL, used by later versions of FLY.EXE. Use alt+g to get a
screen grab. That pcx will have the exact palette you need to use with all graphics to display
without alteration when running  in 16 million colour mode, as all new versions of FLY.EXE do).
256 colour mode is no longer supported. 


Supported PCX files:

INTRO(0 to 9).PCX	(Displaying additional Intro slides, use spacebar to advance)
SFST.PCX 		(Title spash screen, stays on screen for 5 seconds)
SEFST.PCX 		(Death picture... shown if you crash)
SHLP(0 thru 9).PCX 	(Display help screens - if present). Use "H" to access.
MAP.PCX 		(background graphic for around the edge of the 
			 map (leave colour 0 in center)
MENU.PCX 		(background graphic for menu - may not be working).
*.PCX 			(Other pcx files assigned to cockpit dash views or used via -l(filename)
			 to load substitutions via an alias file - see below).

Example:

Alias file can substitute nearly any file (*.pcx, *.fsd, *.wav)
Lets say we save the below as a simple text file called: jetpack.txt containing the following. 

FSTAlias 1
intro1.pcx eva1.pcx
jet.wav eva1.wav


Okay, the first line:  FSTAlias 1  (Must be used exactly as listed for FLY.EXE internal purposes)

Lines that follow the above simply substitute the former for the latter. Example: 
intro1.pcx becomes eva1.pcx; jet.wav  will be replaced with eva1.wav

The command line when running FLY.EXE to utilise an alias file is as follows:

FLY -ljetpack.txt        (note that the switch is  -l (the letter L) and not the number One)

***

Some other (common) helpful Command Line Switches

-c(filename.fcd) use a different color palette
-w(filename.fst) use a different world file

As of 3.29d, you will crash and splash if you land on the sea (sea level 0). If you want this
to be all land (like in a desert), use -

-nz  (Makes the sea into land - will allow "rough landings" without detecting a crash)
