I found a casio c image converter, it gave me the following code:

void drawImage(unsigned int pX, unsigned int pY, unsigned int pFlags){ // Flags: 1 - Draw To VRAM, 2 - Draw to Display

DISPGRAPH picture;
GRAPHDATA picture_info;
DISPBOX boxtoclear;

const unsigned char imagedata[] = {0x00,
0x00,0x00,0x00,0x7D,0xE0,0x00,0x00,0x7D,0x00,0x00,0x00,0x11,0xE0,0x00,0x00,0x11,0xE0,0x00,0x00,0x7D,0x00,0x00,0x00,0x7D,
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x40,0x00,0x00,0x00,0x47,0x80,0x00,0x00,0x44,0x8E,0xF8,0x00,0x44,
0x88,0x20,0x00,0x44,0x88,0x20,0x00,0x77,0xB8,0x20,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0x00,0x00,0x00};

picture_info.width = 30;picture_info.height = 19;
picture_info.pBitmap = (unsigned char*)imagedata;

picture.x = pX;picture.y = pY;picture.GraphData = picture_info;
picture.WriteModify = IMB_WRITEMODIFY_NORMAL;picture.WriteKind = IMB_WRITEKIND_OR;

boxtoclear.left = pX;boxtoclear.top = pY;boxtoclear.right = (pX + 29);boxtoclear.bottom = (pY + 18);

if(pFlags & 1){Bdisp_AreaClr_VRAM(&boxtoclear);Bdisp_WriteGraph_VRAM(&picture);}
if(pFlags & 2){Bdisp_AreaClr_DD(&boxtoclear);Bdisp_WriteGraph_DD(&picture);}

}

How exactly do i use it though? I cant compile it without 20 something errors

Anyone?

What image converter did you use? It might be easier just to write your own routine.

@someone_with_more_experience_than_me: do we know the address of VRAM on the 9860? is it the same as the PRIZM? If so, writing a routine would be pretty straightforward... in fact a routine could possibly be made to support cemetech sourcecoder images.

[Casimo]

Get the vram adress:

typedef char*(*sc_cpv)(void);
const unsigned int sc0135[] = { 0xD201D002, 0x422B0009, 0x80010070, 0x0135 };
#define Disp_GetVRAMPtr (*(sc_cpv)sc0135)

1 bit is one pixel. The address changes on the series, so you shouldn't use a predefined address.

The converter's name is "Casio c image converter".
Instead of this routine, you should better pick just the array imagedata (be careful with the other output mode, there are typos: remove all lines wirth \\ and change the name from imagegdata to imagedata or something different) and use this

void drawSprite(const unsigned char *bmp, int x, int y, int width, int height)
{
unsigned short line;
char shift, *screen, *p=(char*)&line;
int i, j, begin=0, end=height, real_width=(width-1>>3<<3)+8;
if(!bmp || x<0 || x>128-width || y<1-height || y>63 || width<1 || height<1) return;
if(y < 0) begin = -y;
if(y+height > 64) end = 64-y;
shift = 8-(x&7);
screen = Disp_GetVRAMPtr()+(y+begin<<4)+(x>>3);
for(i=begin ; i<end ; i++)
{
  for(j=0 ; j<width-1>>3 ; j++)
  {
   line = bmp[i*(real_width>>3)+j]<<shift;
   screen[j] |= *p;
   if(shift!=8) screen[j+1] |= *(p+1);
  }
  line = (bmp[i*(real_width>>3)+j] & -1<<(real_width-width))<<shift;
  screen[j] |= *p;
  if(shift!=8 && x+real_width<129) screen[j+1] |= *(p+1);
  screen += 16;
}
}

(taken from MonochromeLib by PierrotLL, modified)

Then just call drawSprite(imagedata, [x position], [y position], [height of picture], [width of picture]);

Mabye you could explain how to use it a bit more, i cant figure out how to compile it like this either, and have almost no c experience lol

[shinolife63]

Ok i got it a little further, heres my code:

#include "fxlib.h"
#include "stdlib.h"
#include "stdio.h"
#include "libg85.c"

int AddIn_main(int isAppli, unsigned short OptionNum)
{
    unsigned int key;
    Bdisp_AllClr_DDVRAM();
    drawSprite(5,7,30,19);
    while(1){
	    GetKey(&key);
    }
    return 1;
}
typedef char*(*sc_cpv)(void);
const unsigned int sc0135[] = { 0xD201D002, 0x422B0009, 0x80010070, 0x0135 };
#define Disp_GetVRAMPtr (*(sc_cpv)sc0135)
void drawSprite(const unsigned char *bmp, int x, int y, int width, int height)
{
unsigned short line;
char shift, *screen, *p=(char*)&line;
int i, j, begin=0, end=height, real_width=(width-1>>3<<3)+8;
if(!bmp || x<0 || x>128-width || y<1-height || y>63 || width<1 || height<1) return;
if(y < 0) begin = -y;
if(y+height > 64) end = 64-y;
shift = 8-(x&7);
screen = Disp_GetVRAMPtr()+(y+begin<<4)+(x>>3);
for(i=begin ; i<end ; i++)
{
  for(j=0 ; j<width-1>>3 ; j++)
  {
   line = bmp[i*(real_width>>3)+j]<<shift;
   screen[j] |= *p;
   if(shift!=8) screen[j+1] |= *(p+1);
  }
  line = (bmp[i*(real_width>>3)+j] & -1<<(real_width-width))<<shift;
  screen[j] |= *p;
  if(shift!=8 && x+real_width<129) screen[j+1] |= *(p+1);
  screen += 16;
}
}
const unsigned char imagedata[] = {0x41,
0x38,0x00,0x00,0x41,0x44,0x00,0x00,0x63,0x40,0x00,0x00,0x63,0x40,0x00,0x00,0x55,0x38,0x00,0x00,0x55,0x04,0x00,0x00,0x49,

It seems to work better than the other code, but it still has 1 error when i attempt to compile. The output:

Any ideas?

Got it to work, had to change the drawImage thing from a char to an int
