2 questions - tunaVIDS & Differcde between EUR and US roms

Hi, i have 2 question!
First:
How to i play AVI/XVID on my NDS (M3 Sakura & Real)?
I already tried but i get this error: GURU MEDITATION ERROR
Sounds stupid ;-)
Second:
What is the difference between EUROPE and USA roms?

No idea on first question...(E) and (U) roms are just region specific.E-games in europian regions ie australia, UK, holland, etc...They might have addition language selections based on where they are marketed.(U) is american, and usually made and 9 times out of 10-dumped before (E) games.Can also be mexican though, I seen one...(J) is jap of course.

(U) is north american, in other words canda, US, mexico and related territories.
