@godreborn I read about your post, I think you can also use DayViewerForGame, it is basically the same as the plugin for VSH but for the GAME home menu, and you can use it in conjunction with HUD...
actually it is only a triple boot, the fourth boot does not exist since you are using Infinity in OFW mode which I guess is the one you consider the fourth boot. at least that's how I see it
the plugins in Vita Adrenaline like HUD if you open its configuration menu it suffers performance drops I think it is due to its bilinear filter that PS Vita uses.
