After looking around seeing some people able to update there game i was wondering what the best way to do this was, as there is no 1.05 in the retail update list on the site only the undead add-on?

So couple of questions:

1. Does hermes v4 let us install pkg updates?
2. Do we need that waninkoko add on for it to work.
3. Can i update directly when the game asks me to on the ps3 or do i use a front end to grab the pkg and install it?
4. Do we still need to update games in order ie 1.01, 1.02 etc.?
5. Are the update methods the same for each game but only some work with updates?

Sorry only had my jb ps3 for a couple of days and just trying to suss it all out
