Will this setup work?

[The Hombrew Hunter]

GBA movie Player
1GB Mini SD card
MAX Media Launcher

This should work hum?

I want to run DS homebrews, DS backups, NESTER DS, SNES DS, PicodriveDS, and DS GBC. Will this work for those efficiently?

Will it utilize both screens using an NDS file?

I also have ndsmp. Is that needed for an nds file?

when you say "DS Backups" as in commercial roms, no they will not work with the GBAMP if you get an M3 though they should, SNES DS works but....the Superdat file thats needed for graphic fixes and other things, is taken out of the GBAMP version DS GBC im no so sure of, PicoDriveDS works..kind of slow though but i think it will improve over time, and for homebrew, about 98% of homebrew ive tried works

~EDIT~

I use NesDS and it works great, but it cant save, and i just noticed you said your using a MiniSD card, so i gues you were using a M3 all along..?
