Don’t submit the output XVCs from Split Package (splitpkg.exe) into the Microsoft Partner Center publishing system. You’ll submit your master XVC along with your DiscLayout.xml file. Splitpkg.exe will be run as part of the publishing and disc-mastering process.
Any chunks in your title’s DiscLayout.xml file that precede the chunk with the
Marker="launch" attribute (that is, any chunks in the title’s launch set) are always included on disc 1, if possible, so that XBOX One X-specific assets in the launch aren’t placed on disc 2.SplitPkg command, along with the XVC generated by Make Package (makepkg.exe) and your DiscLayout.xml file, to generate your test disc XVC files. We strongly recommend that you burn test discs to validate your installation experience.
The individual files produced by Split Package can be sideloaded by using xbapp install (NDA topic) or XBOX Manager (NDA topic). Assuming that the previous example layout was used, the following command installs disc 1:
Xbapp install PackageName_1.0.0.0_x64__8wekyb3d8bbwe.GameDisc.1
After installation of the content from disc 1 is completed, the XBOX shell notifies the user to insert disc 2, which can be accomplished similarly as follows:
Xbapp install PackageName_1.0.0.0_x64__8wekyb3d8bbwe.GameDisc.2
