How to use it

1. Open wonderdroid at least once so that it can create the directories for roms etc
2. Copy your game roms in either zip archives or plain .wsc or .ws files onto your sd card 1 in the wonderdroid directory that has been created there. Zips with multiple files should work but it's not been tested.
3. Open wonderdroid again, it should now have a gallery of the roms you put into it's directoy. Wonderdroid uses the metadata in the rom to select a screenshot.. if a game has a question mark it will probably still work. It just hasn't been screenshot'ed yet

1 - Some phones like the Samsung Galaxy S2/S3 put a block of internal storage where the sd card normally is. If you have such a phone you need to copy roms to the directory created in the internal storage instead. The application asks android for the location of the "external storage" which is usually the sd card but in these phones it's "internal external storage".
