The First Hex of Skull Master Z

Bump for solved. I hate you.

Interesting little puzzle. Are all of the answers in the interactive website, then?

A random Desura key for a bump:
HAWW2-7*Y4S-114AK-G*Q*H-3WPSP

Replace each * with a digit.

Hint: The missing digits make up of the name of one of my Boss' favourite adventure games. It ain't a PC game.

got all but stuck on Q3, I click on some letter and pass that, just don't know what I answer

bump for solved :D

Bump for solved!

Bump for finally solved! This was so difficult!

While I'm perfectly fine with a small number of entries, it wouldn't be fair (especially to Master Z) if I didn't bump it again.

Oh and this still works on Desura, I hope:
3CAB*-F2257-8*231-2**25

Same as last time, all same digit.

HINT: They say the fear of this number is a common superstitious in East Asia. Wooo, spoooky!

The penultimate bump.

Desura, as usual:
64WJ-M*3N-23NB-063*

This time * is to be replaced by the digit most favoured by the Chinese.
