One limitation you should be aware of is that some of the .bkg files must
not exceed a specific file size. This only applies when F1GP loads in more
than one .bkg file at a time (by storing them in a fixed size buffer). If
the combined size of those files is too large, F1GP will issue a "Not
Enough Memory" error message and the backdrops for that section will either
be blank or kind of corrupted. This isn't serious - it just means you
can't see your chosen backdrops. There are 2 instances I can think of:
1. After a non-championship race, F1GP will load both honda1 and result
into a buffer. The combined size of both these .bkg files must be less
than approximately 60000 bytes.
2. After a championship race, F1GP will load result, d_champ, c_champ and
pitcrew2. The combined size of these .bkg files should not exceed
approximately 130000 bytes.
In the following text I shall refer to specific entries in the colour
palette using the range 0-31 inclusive.
The mouse pointer will always use palette colours 16-19.
STATIC SCREENS (unrestricted)
It is feasible to use all 32 colours in these pictures, as the picture is
only every shown on it's own (i.e. no menus).
crash1 Out of race - no wing damage
crash2 Out of race - one wing damaged
crash3 Out of race - both wings damaged
podium 3rd place?
runnerup 2nd place?
setup3 Car setup - return to car
Colours 14-23 & 31 are used by F1GP to render the menus on top of these
options Main menu
pitcrew2 Championship results menu
setup1 Car setup - load/save menu
setup2 Car setup screens
F1GP also uses colour 24 (this is the blue colour used as the background
colour for "popup" requesters) from the following:
monaco Track select
honda1 Prac/Qual/Race select
track1-16 Circuit maps
pitcrew1 Return to cockpit / save
F1GP uses the entire palette (I think), to render the drivers' helmet
designs. Therefore, you should probably keep to the original palette:
helmet Driver select screen
FADE-IN + DIM SCREENS (palette change)
Colours 14-24 & 31 are used by F1GP to render a menu bar at the bottom of
the screen. Text is overlayed directly onto the image. The limitation is
that once the picture has faded in, it dims to about half brightness - this
dim palette is hardcoded in the F1GP executable file (F1GP-Ed will change
away Starting grid screen
c_champ Constructors' champ result/table
d_champ Drivers' champ result/table
result Race result / fastest laps
uno Game complete (won season)
You shouldn't change the part of the image that moves in the animation - in
most of the images you'll see a missing chunk (black box) which is what
gets altering in the animation. It should be ok to alter other parts
though. You should be careful when altering the palette too. The other
anim frames are loaded from the corresponding .MSP file.
champers 1st place
trophy Won championship
Obviously the logoanim.bkg file is an animation, and as you may notice from
it's size it is not in the same format as all the other .bkg files! Again,
this is used by the intro. F1GP-Ed cannot alter this file.
