+For ability to have better upscale than Cxbx-Reloaded's upscale hack method. You will need to download dgVoodoo** then put two files in same folder as where `cxbx.exe` file is in, which are `D3D9.dll` *(can be found in MS > x86 folder)* and `dgVoodooCpl.exe`.
+
+1. Open dgVoodooCpl.exe file then make the changes from the list below.
+   * **General tab**
+     * Output API: **DirectX 11 (feature level 10.1)**
+     * Adapter(s) to use / enable: **Your current graphic card or integrated graphic**
+     * Scaling mode: **Centered, keep Aspect Ratio**
+   * **DirectX tab**
+     * VRAM: **1024 MB (or higher, untested)**
+     * Resolution: **Change to your monitor's native resolution**
+     * Application controlled fullscreen/windowed state: **untick**
+     * dgVoodoo Watermark: **(optional) untick** (REMARK: We suggest to leave it on to ensure dgVoodoo is working on your side. Then untick after confirm is working correctly.)
+   * Click **OK** to save the changes.
+2. Open cxbx.exe file then perform the changes below from `Settings > Config Video...` dialog:
+   * Video Resolution: **640 x 480 32bit x8r8g8b8 (60 hz)**
+   * Use Hardware Video Mode: **tick** (REMARK: Hardware Video Mode is fullscreen mode)
+   * Force VSync: **tick** (REMARK: This is optional unless you are seeing screen tearing, then turn it on.)
+   * Click **Accept** to save the changes.
+3. Launch your favorite title then enjoy the upscale mode! 😉
+
+** Required `dgVoodooWIP58.zip` since it only has D3D9.dll hook file at the moment.
+
+***
+
+**REMARKS**
+  * We do not accept issue reports when using any third-party programs that altered Cxbx-Reloaded internally in any method, including dgVoodoo.
+  * Modern monitors does not support 640x480 resolution and will output an error of `IDirect3D::CreateDevice failed`.
+    * except dgVoodoo will take over and upscale of given resolution from **dgVoodoo.conf** file directly for you with the steps given above.
+  * When stop emulation, you will need to restart cxbx.exe in order to start new emulation.
+
+***
+
+For those do not know where the changes should occur in dgVoodoo's Control Panel can look at the screenshots below.
