I'm kind of new to all these and I was wondering wich is better. Also, can I play DS games on the GBA movie player if I have a Passkey? Thanks
The M3 is superior to the GBA Movie Player as the M3 has it's own 32MB of RAM and a battery for SRAM memory. You cannot play GBA games or DS games using the Movie Player, but you can with the M3. Both can be used for GBA/DS homebrew, however the Movie Player has a 4MB limit (in DS mode) unless the homebrew was designed especially for it. I have both the M3 CF and the GBA Movie Player CF, and since getting my M3 I have not used my Movie Player for anything but DSLinux So i'd recommend getting the M3.
