Possible to tell if an Address is a Base Address (Static)?

[Zerowalker]

That was way beyond me.

First, what is rtoc?
I have seen that function several times, and sometimes it seems to be r1, and other times r2, which doesn't make sense?

And what's special about register 13?

And BSS, no clue what that is?

the last part made no sense to me either, but then again i haven't looked at a DOL either so i guess it will make sense when i do;P

Thanks
