i don't remember, but i have lot of problems like this and currently i am in 4th world...try to use touch screen, it always helps in these situations. Propably you must split the walls.
Why games that works on my flash (goldeneye, Spiderman2, Bomberman) want to connect with something (or download something) and then crushes? why they cant normally run...?
I tried 10 roms, all crushes (white screen), only 2 of them (goldeneye and spiderman) want to download something and then i have a message "press A button to turn off"
