FLI C64Gfx FLI
NAME
FLI - a C64 graphics format
DESCRIPTION
FLI is the newest and most time consuming graphics mode in C64.
The processor is busy the whole time the picture is displayed,
and thus FLI is not very usable in games or other programs that
need a lot of processor time.
You can find more description about the what-and-how of FLI
elsewhere. Here I just describe the FLI file format. I don't
know if any other format exists though. The file consists of:
Offset Address Size Used Description
------ ------- ---- ---- -----------
0 - 2 2 Load address ($3b00)
2 $3b00 256 200 Background colors for each line
258 $3c00 1024 1000 Color memory
1282 $4000 8192 8x1000 FLI color memories
9474 $6000 8000 8000 The bitmap (multicolor mode)
The reason for the unused areas is simply the speed. You can
load the FLI picture right into memory and you don't even have
to move it elsewhere in memory (with the exception of color
memory of course).
The load address is of course hidden from you when you load the
file into the C64.
