Ah, no problem, I hope it was good :)

There were some changes yes, it seems for some reason they are not being
used. I will double check. I probably simply forgot to remerge the
default registry, thinking about it. My mind wasn't very clear on
anything by friday :)

In Delphi/Object Pascal passing an array like that would perform a copy
by value, not pass the address. I (wrongly) assumed C would have similar
rules. This is what I get for learning it as I go :)
