are there rules against using trademarked images?
On this forum we are pretty lax about copyright and trademark law Flopsy has, for example, included in his flopsy_special style the logos of Irn-Bru, Sonic the Hedgehog and The Crystal Maze, and I don't think he strictly holds the rights to any of them
Not to mention the amount of tilesets on this community which are based on other computer games in general, that would be a hazard in itself if any of the rights holders of said computer games took issue like SEGA for example (my Sonic tilesets).
And no I do not hold special rights to any of these but with the amount of Irn Bru I drink, I'd might as well be a shareholder in Barr
Look forward to seeing your pack when it is finished anyway mantha
