Map as Background in menus

[jreagan406]

I found a neat little Menu Scene script that uses the map as background. I want to show the background on every other menu. I'm using the standard RMXP scenes for Item, Equip, and Status. I really don't want anything flashy, just something simple and that works... Is there a way I can edit these, the original scene scripts, to make the map as the background? And how?
