I've been following the guide in the hdlpatch readme.txt regarding adding my own font to a HDL skin.
Use Bitmap Font Builder (http://www.lmnopc.com/bitmapfontbuilder/) to
create the needed BMP and DAT files for font patching with the
Texture Size: 256x256
Background: 1 1 1
Foreground: 128 128 128
Font Alignment: Left
Character Set: Full ASCII
Save the font image as BMP & Font Widths (Byte Format) DAT using the
same filename (file.bmp + file.dat)
However, no matter how many different fonts I try, they always appear as garbage once injected into an .elf. I know it's not my patching method because with somebody else's font.bmp and font.dat files it works perfectly.
All I can assume is that Font Builder is fussy about the choice of font. Any recommendations folks?
