Hi Miller,
Welcome with the Team M3
For your first problem, you must download this software.
M3 Movie Converterhttp://www.m3adapter.com/download/M3%20Movie%20Converter-en.rar
Then for your second problem, you must use Game Manager to patch your roms and transfer them on your card SD.
The file of save will be creating automatically on your card SD.
Download game manager for your card Sd here

Don’t forget to put an original game inside your PassMe, like the demo of Metroid.
Ps: the homebrews are not compatible with the SD cards, at last I think
