What's needed to play movies on DS?

I have an R4 and I have the movies in .dpg format. What kind of emulator do I need to play them? I guess the one I have to play the games isn't the same. Any help would be appreciated! I am trying to load movies onto my kid's DS systems for a trip we are taking next week. Thanks!

Hmm since you have an R4 I guess you're set to go. Just go create a folder to put your videos in
and then play them on Moonshell. Moonshell should already be on the R4. No need for an emulator.

Yep, I did all that and it's not working. When I try to play the movie it doesn't even show the title and keeps sending me back to the directory when I click on it?

Nevermind! I think I figured it out. I will post back if I need more help. Thanks!

You probably didn't convert it right. Use SUPER etc.

It was already converted to a .dpg for me..I figured it out though...Got them to play. Thanks!
