Hi all. I would like to use old pacman sound effect and some images to make my own game.Do you know if it's legal? there are problems of copyrights?
There was another discussion about copyrights here http://www.gamedev.net/topic/544351-can-you-give-away-free-remakes-of-old-games/ (very polemic, indeed and with opposite opinions), for example:
Names, ideas, concepts and techniques cannot be copyrighted, in other words, the actual game aspect of a game cannot be copyrighted. I don't know why people are implying otherwise to be honest.
The parts of a game that can be copyrighted are sounds (sound effects and music), graphics (photographs, icons, fonts, sprites, etc), literature (instructions, dialogs, etc) and cutscenes.
So you can recreate Pacman without copyright issue provided you don't use the same sound effects and sprites (or sound effects and sprites that have been derived from the originals). If you make brand new sprites and brand new sound effects then you're fine. Though you might not really consider it to be a Pacman clone by then perhaps.
This another website speak about that:
