I'll drop it on here too, just in case.
About che 'locked' palettes and stages on 360 Encore.
I think it depends on the savedata (as in the old 'Skullgirls' savedata clashing with the new 'Encore' updates maybe?). Until yesterday I had all the colors and the new stages locked in Training Mode and then I tried this: I
- activated the Cloud device on my 360
- copied vanilla Skullgirls savedata from the HDD to the Cloud
- deleted vanilla Skullgirls savedata AND the 7MB game update from my HDD (I didn't touch the game, the 820MB compatibility pack and Squigly/Big Band DLCs)
- booted Encore, redownloaded the 7MB game update
- selected my HDD as the destination device for the new savedata.
At this point, it all worked.
There are still a few palettes and stages locked (it's normal, you are meant to unlock them by playing the game) but all the stuff which is supposed to be selectable from the get-go is now actually selectable.
After that, I just deleted vanilla Skullgirls savedata from the Cloud and then I deactivated the Cloud itself.
***PLEASE NOTE*** that by deleting your original savedata you will lose both Story Mode and Training Room progression so keep it in mind before doing anything.
