Developer / Publisher?

[NES_Rules]

I've noticed many games have one or both of these fields empty, and I want to fill them in, but I don't know how to tell which one is which. Anyone have some tips to tell them apart. It seems very few games come right out say "published by ____" or "developed by ____".

If one field is filled out and there is another name, should one just assume that the other name is the other field. For example, I'm looking at Brutal: Paws of Fury (SNES) and the page says the publisher is Cybersoft and the developer is blank. The title screen says GameTek, so should it be assumed that GameTek is the developer?

Not necessarily..

There is also distributors and copyright holders.
distributor logos don't normally show up in the game itself but copyright holders do so it could just mean Gametek hold the copyright for the game but they didn't actually have anything to do with the snes version as such.

edit: just loaded the game and it clearly says it was developed by Eurocom Entertainment Software.

Yeah, I loaded it to find out something else, and saw that too. But I was really just using that game as an example.
I'm hoping to be able to just look at the box of the game or the game scan itself, and figure them out. That way I can do it at school when I don't have the actual game handy.

Unless it clearly says what each company did, don't assume anything.
It's the only safe way to go about it.
