msd..? MSD..? The same msd who only codes stuff for screen 0 and g9k? That 'msd'? 
Now im working on this unoptimized code:
#include <stdio.h>
#include <msx/msx.h>
#include <ctype.h>
#include <string.h>

p_fcb->name[i] = ' ';
}
for( i = 0; (i < 8) && (p_name[i] != 0) && (p_name[i] != '.'); i++ ) {
p_fcb->name[i] = toupper( p_name[i] );

if( p_name[i] == '.' ) {

Can be compiled with SDCC.
Can be used to load bmp files directly. 
... in screen 8
I personally do all my graphics in Paint Shop Pro (7, didnt like later releases) - If for scr5 I just reduce colour depth to 16 (there are two different ways the programs allows you to do that, both with and without dither); if scr8, I just load an scr8 pal I have... Then I just use the image converter on MSXPad to create the raw file for me 
For MSX1 I try to color everything in 8x8/2 colors line, with the help of an 8x8 grid using an MSX1 pal, then I just throw the image on MSXViewer to see if I don't missed anything and to convert it to "bloadable" SCR2 file :)
