Combine multiple ported j2me games into one j2me "gamebox"

Hi, I would like to create a tool which is capable to combine 2 or more complete java games (each ported in different resolutions and with its own jar/jad file) into 1 java jar/jad"game box". This means that the tool must put the two or more jars into a combined one featuring a main menu for the user to select the game he wants to play. Flow would be: User starts"game box" -> main menu with games selection appears showing game 1,2,3... -> user selects e.g. Game 2 -> selected game 2 starts -> if enabled advertismentbanner is shown -> user starts and plays game 2 -> when user closes game2 he returns to main menu with games1,2,3,... overview appearing again To wrap up the function of the tool: a) Combining ported jar/jad files for different resolutions/device into 1 game box file b) Possiblity of defining the game names and headline in different languages for "game box" main menu c) Possiblity of defining the game box title screen for each resolution or leaving it empty d) Possiblity of adding an advertisment pop up with banner/link before each game starts e) Supporting all resolutions and different jar/jad file e.g. 176x208,176x220, 240x320,...etc Thanks and looking forward to see your bids.
