Hi, the display of LSS16 files from a DISPLAY file (as documented in http://www.syslinux.org/wiki/index.php/SYSLINUX#Display_graphic_from_filename:) seems heavily broken since syslinux has been converted from assembler to C. I already discovered one bug in core/include/graphics.h (and core/graphics.c): the pointer VGAFilePtr is of type uint16_t*, but should be plain char*. This bug causes the

We recently have upgraded syslinux and have noticed that the boot logo code via boot.txt no longer works. I have a couple patches that get it close to working but I appear to be having trouble with color maps. Is there someone would want to help me finish figuring this out? Any interest in the patches I have to fix the rle decoder?
