Would it for any reason be problematic for gameplay that after sshing ROM's into their appropriate folder on my itouch that i set their permissions to 777? Additionally, I was playing zelda- link to the past on snes4iphone and for some reason parts of the environments were invisible, as I found myself unable to move and assumed there were supposed to be houses. So, the question: is this a bad rom, or is this just a fault of snes4iphone. Furthermore, are there such things as more iphone-friendly roms? If so, could someone provide me with a link? All help will be greatly appreciated. Thanks.
