Make a bitmap of the new screen (use whatever you like to make it look pretty). Download Muxman and VobBlanker and install them anywhere convenient. Set up VB for your temp folder and for the path to Muxman.
Now substitute the homemade BMP for the original screen. Essentially click Process on the VTS with the menus. Double click up the top and this will open the menu PGCs. Next, double click the PGC with the screen you wanna replace. Now, click the cell and click Still. Select File from the dropdown box and go to the new BMP. OK and close and OK a few more times till you get back to the main GUI.
Tick process in place and process menus (untick process titles). Click process down the bottom and you're there. Sounds hard, it's actually easy and there's a guide on the site (see here).
