Ok guy after many people asking me for a tut, here i will show how to change Corby 2 Homescreen, Menu, Lockscreen and etc.
First you need to download Wave Remakerhttp://www.badania.de/wp-content/downloads/Wave_Remaker_NEW_0_2_8.exe
Open it then drag your preferred RC1 file to the Wave Remaker in FW view tab.
Wait until it say Dump completed.
Now you will have a new folder named "Bada" in the same location of your Wave Remaker.
Open it and you will see one more folder in the folder that it name is same as the RC1 file you opened before this.
Open it and now for Homescreen go to Rsrc>Flash>Idle. The homescreen is gadget.swf, for Menu go to Rsrc>Flash>Menu. The Menu is MainMenu.imswf, for Lockscreen go to Rsrc>Flash>Lock. The lockscreen is ScreenLock.imswf.
Other thing you discover it yourself
So for homescreen you can directly mod it using Sothink SWF Quicker but for menu and lockscreen you must rename it to .swf when you want to mod it then after finished rename it back to .imswf.
And dont forget to replace the original file with your modified file.
Now after all is finished, at Wave Remaker click File>Save as non compressed .rc1 and you will have a the modified rc1 in the same location of your Wave Remaker.
