MountainmanJed and team put out a fixed version of selfboot.zip that you should integrate into your images. This unlocks all the stages/characters by default without needing a VMU as well as fixing random stage select to use all the stages. This package is linked at http://zachd.com/mvc2/colors/tools/ComboMasher/Combomasher%20Guide/index.html . I also folded it into the ComboMasher download package.
