@lucky1, can you confirm that X-Men machines, specifically, have the capability of using side channel loading? We never added slots for X-Men in the source. We may need add these if this project is going to load correctly.
Yes, X-Men has the capability to support side channel. To load the serial patch with pinball browser you need to select serial side-channel in the SmartDMD tab and then use load patch in the SAM tab to load comm120.hex located in the pinball browser folder. It should ask for the serial number. It is true that serial side-channel needs a serial connection in real pinball installations but for pinmame we (RobX and I) have implemented this in the dmddevice.dll interface. WPT uses the old ROM structure like Shrek and POTC which does not support the comm patch and must use inframe coding or pin2dmd editor keyframes to switch palettes.
Steve has released a new version of the editor which finally fixes the free vpin export. This time I removed my activation key from the system and tested it myself. 
Download it from https://bintray.com/sker65/pin2dmd/Editor2#files/
If you run into memory problems with the X-Men colorization feel free to contact me and I can see what I can do. Just split the project into different macros and continue to colorize the scenes. We can find a way to merge them in the end. Did this with Sharkky several times (ST, Avengers etc)
