No, they don't. xpize 5 is built on an entirely new framework and shares nothing with XPize 4 (for instance, it doesn't use reshacker anymore, it does the resource patching by itself). If you want to modify the xpize package you can extract it and edit the XML file manually. That's cool, it's not like it is that hard to click a few mouse buttons and integrate it into my install discs manually. I like the look of the darkside theme. Good work on that.
