okay they were talking about there previous posted topic where they asked someone to change the image in a title screen (even posted an email address along with an image to upload and put in for them) pretty much asking to upload a rom for them advance wars dark conflict - changing the title screen - either to the japanese one or to change something - edit the image in there to something else -I don't know they never answered me back either way big time against the rules uploading thing and no use of the SEARCH button
so the reason you are having trouble with the .narc file is it is compressed and you will need something called the narc tool to fiddle with that file...
try to keep posts relating to each other together okay
you started a thread for this already, just post in it okay
and do yourself a favor lookup (type into google search pane) nds rom image editing or tile editors nds or just anything you would like to know more about... I'm still confused as though do you want the japanese title screen in the eu or u version (why?)
or do you want to change it to your own custom screen?
cause to change the eu u version screen to the japanese one is as easy as replacing the files from the eu u version with the ones from the japanese version no image editing involved just copy paste and replace or name change and replace...
oh vay
