Help with Datel's Games n' Music and homebrew

Yeah Hey, I'm kinda new to all this homebrew stuff and I had some questions about somethings. I have Datel's Games n' Music. I was wondering, is there any chance of that Zelda platform game to work on my Games n' Music? and on NitroTracker how do I load the WAV files? and can't get MyMeloDS to work do you know anything about that? and what's the program in this vid?http://www.youtube.com/watch?v=AlUEjgk-rjE

I looked up the name it had but couldn't find it..

You mean one of the Zelda GBA/NES/SNES ROMS?
If you have one, it should run - you just need one of the emulators.

I have a Games n Music card, DS Lite with the FlashMe firmware (just to get rid of the health warning screen, mostly).

I'm running DSOrganize (IMNSHO a "must have" if you've got a lot of homebrew and ROMS), a number of NES/SNES and GBA emulators (some work better than others - I'm still deciding which one I prefer - though I really like SNEmulDS for SNES) and a LOT of ROMS for various systems.

There's a list of available emulators here.

Can't help you with your question about DSDrummy or NitroTracker, as I'm just not interested in that sort of thing, so I know nothing about 'em.
