Request: App to overwrite files in \windows at startup

[Guest crafty]

Hi all you clever programmers out there - i'm hoping that someone can help me out with a (hopefully simple) app. As the title suggests i would like a programm that will replace certain files in the root windows folder at startup with files from another folder on the phone. The files in question (C500 only) are homescreen_MenuF.bmh and homescreen_MenuS.bmh, which control the look of the default C500 homescreen (as described in this tutorial i did).

There's already a program out there called patcher but unfortunately this does not work with the files in question.

I would be very grateful if anyone could take up this project. ^_^
