Hi Colin,

	Maybe I can be of some assistance.

 GsGetTimInfo copies the information store in the tim into the GsIMAGE
structure.  So just supplying a pointer is not enough.  Probably a case
of poor documentation.

This should be ok.  I have not had a chance to compile this so there
could be an odd glitch or two.

Hope it works

Regards

Jim

void InitTexture (u_long *addr){
  GsIMAGE Info;
  RECT rect;

// skip header  
  address++;

// parse tim header
  GsGetTimInfo(addr, &Info);


// set position  of bitmap in vram
  rect.x = Info.px;
  rect.y = info.py;

// set size of bitmap
  rect.w = Info.pw;
  rect.h = Info.ph;

// Load the bitmap
  LoadImage(&rect, Info.pixel);

// Wait for it to finish uploading
  DrawSync(0);



// Now load the clut to vram

// Check that there is a clut
  if (Info.pmode & 8){		
    rect.x = Info.cx;
    rect.y = Info.cy;
    rect.w = Info.cw;
    rect.h = Info.ch;
    LoadImage(&rect,Info.clut);
    DrawSync(0);
  }
}
