Dingoo A320 forum

This is fantastic, thank you Alekmaul! I'll always have a special place in my heart for the TG-16.

I also think that turbo-fire would be a great addition. (ie: Y=turbofire B, X=turbofire A)

Like a fine wine, the Dingoo keeps getting better with age.

Thanks so much Alekmaul! I love the TG-16/ PC engine. I can't wait to play your final update of the emu.

It would also be great if you could have the TV out function implemented on your emulators. Any chance of that in the near future?

Keep up the great work! You rule!

Ok, here are the progress:
I fixed timer int pb and now lots of games work (with gfxs pbs for some games but they work).
Only two games hang during actual tests : pacland and turrican.

About TV Out, i really don't know where is the pb. If someone can help, here is the source code of the main part with the scale function (botmap scale) that update the video buffer.
Hope someone can see something wrong ...

Code: Select all

void bitmap_scale(int viswidth, int visheight, uint16_t *bmpline) {
  uint16_t* buffer_scr = gfx_render_target->address;
  unsigned int W,H,ix,iy,x,y;
  x=0;
  y=0;
  W=320;
  H=240;
  ix=(viswidth<<16)/W;
  iy=(visheight<<16)/H;

  do   
  {
    uint16_t *buffer_mem=&bmpline[(y>>16)*SYSVID_WIDTH+0x20];
    W=320; x=0;
    do {
      *buffer_scr++=buffer_mem[x>>16];
      x+=ix;
    } while (--W);
    y+=iy;
  } while (--H);
}

int main(int argc, char** argv) {
  strcpy(gameName,argv[2]);
  int ref = EXIT_SUCCESS;
  srand(OSTimeGet());

  control_init();
  control_lock(timer_resolution / 4);
  gfx_init();
  gfx_render_target_clear(gfx_color_rgb(0x00, 0x00, 0x00));
  gfx_render_target_swap();

  gameTimer   = timer_create();

  _audio_music = waveout_open(&tempArgs);

  m_Flag = GF_GAMEINIT;
  sndLevel=20;
  m_ScreenRatio=1; // 0 = original show, 1 = full screen

  render_screen = m_ScreenRatio == 1 ? bitmap_scale : bitmap_noscale;
 
  uint32_t tempTick  = 0;
  uint32_t tempPauseOS = 0;
  int sysref;
       
  while (m_Flag != GF_GAMEQUIT) {
     sysref = _sys_judge_event(NULL);
    if (sysref < 0) {
       break; 
    }
 
    switch (m_Flag) {

      --- /// -----
      --- something here without any interest ----
      --- /// -----
            
     case GF_GAMERUNNING:
      tempTick += timer_delta(gameTimer);
      if (tempTick < gameTickRate) {
        tempPauseOS = (((gameTickRate - tempTick) * OS_TICKS_PER_SEC) / timer_resolution);
        if(tempPauseOS > 0) OSTimeDly(tempPauseOS);
        while(tempTick < gameTickRate)
         tempTick += timer_delta(gameTimer);
      }
    // Do a one step emulation
    do_frame();
      render_screen(disp_width,disp_height,buf16RGB);
    gfx_render_target_swap();
 
    waveout_write(_audio_music, rawSoundBuf, PCESND_STEP);

          --- /// -----

      --- /// -----

       break;
    }
  }
 
  timer_delete(gameTimer);
  waveout_close(_audio_music);
 
  gfx_term();
  control_term();
