I've been really frustrated with this emulator. i have the no$gba version 4.2 a and the first time i used it i couldn't play pokemon pearl or diamond and even Phoenix Wright, but then i figured out the problem and that was that i had to unzip the folder that the rom was in then i was happy about...
every time i start to play pokemon pearl it works find at the intro then when i get out of the house i can walk good a little bit and then thats when i get an error report window. it never gave me time to see my first pokemon. how should i fixed this problem so it won't happen again.
