How to Convert Most Video Formats to .Dpg in Mac Osx

Aug 28, 2009 11:17 PM

If you own a Nintendo DS with some sort of flash cart (eg. R4DS, Supercard, M3 etc), you can almost certainly run a homebrew multimedia program named Moonshell. Moonshell is able to play videos, but they must be in .dpg format. While many solutions for converting other formats to .dpg exist in Windows, there have been remarkably few efforts to create a similar program for Mac OSX. This guide outlines the best and easiest method to use on Mac OSX.

Setup

Download the software listed and create a folder named Mac

DPG Conversion.[DPG Converter]

Place the files inside this folder and extract, open any

Disk images and make sure that all the applications listed are placed there.

Creating the right AVI

Drag your chosen video onto MPEG Streamclip and go to File

> Export to AVI.Make sure that it is encoded as a 15 fps 256*192 avi with MPEG-2 128 kps sound. Now click Make Avi. When your AVI has been converted, open it using MPlayerOSX (if you have not bought the Quicktime MPEG-2 plugin) and check that the video has been converted properly. If the video has been 'squeezed' -everything has been made thin and tall- change your Zoom X/Y settings before reconverting the video.

You can now check your AVI using MPlayerOSX or/and VLC.

Creating the DPG

Open DPG Converter and open Prefences

Make sure that video quality is set to best and audio quality is set to better. If you want your video in stereo, be sure to tick the Stereo box. Click done.

Drag your

Avi video into the window and click Start You should now have a working DPG. Connect your flash cart to your computer and drop your video to a chosen folder.

Playing the video file

Boot up your flash cart and open Moonshell

Find your video and watch.

AVI Tips

You do not need to purchase the Quicktime MPEG-2 plugin if

You wish to convert from DVD to DPG or wish to view AVI files.

Some of the compression settings will lead to bad quality

Or overly large files. Quality settings that work well include Apple Photo - JPEG at 65% quality or Apple PNG (quality seems not to matter with this type of compression).

Checking the AVI using BOTH MPlayerOSX and VLC will make

Clear that any playback problem is the fault of either the video file or video player.

DPG tips

DPG Converter will crash if the preferences are changed

Twice in one session.

Users have reported that video lags slightly behind sound -

You may want to experiment with your own DPG Converter settings.

Moonshell Tips

This DPG Converter will only create old DPGs -not the new

DPGs that allow instant jumping to any point in the video and usable rewind/forward-wind. When skipping sections the colours and shapes of the video will mess up, but this disappears a few seconds later.

Moonshell - when downloaded from its homepage - is packaged

As a windows .exe, so you will need to download it from the R4DS homepage, where it is named DS_MSHL.nds.

Other Tips

Try to use the stable versions of the programs listed, as

The unstable versions may have bugs that affect the conversion.

MPEG Streamclip also allows you to save and convert youtube

Videos and other streamed videos.

Warnings

  • MEncoder MUST be in the same folder as DPG Converter for the final conversion to work
  • You may need a few gigabytes of space on your hard drive if you are converting large video files.
