There are three fonts associated with ROMWBW supported hardware - ECB-SCG, ECB-CVDU and the ECB-VGA3.

For inclusion in HBIOS the .bin format files must be convert to assembler .asm format.
|
|
This is acheived using the fonttool utility and is completed automatically as part of the build process.
|
|
i.e. fonts files are converted to .asm format and then copied to the HBIOS directory.
|
|
|
|
To replace a font, simply copy it to the Fonts directory using the same naming convention above,
|
|
ensuring format and size match. Then complete a new build process.
|
|
|
|
To reduce the size of the HBIOS image, fonts can be compressed by using the USEZLSA2 equate.
|
|
|
|
Use the following in your custom configuration to turn on font compression:
|
|
|
|
USEZLSA2 .SET TRUE
|
|
|
|
Compressed fonts are created using lzsa utility.
|
|
|
|
During the build process, fonts are compressed using the command line compressor by Emmanuel Marty
|
|
The compression is done as follows:
|
|
|
|
lzsa.exe -f2 -r <sourcefile> <outfile>
|
|
|
|
where option -f2 selects lzsa version 2 compression.
|
|
where option -r asks for the generation of raw (frame-less) data.
|
|
|
|
