Did you rip them? Because then people certainly have to credit you.
Well, all of the tiles were already ripped. They could be found all over the internet. Either way, some were partly ripped. I ripped most of the floor and house tiles, and the dungeon entrances and etc. (Most of the "inside" collection). The LTTP rom came in handy. As for outside tiles, I ripped most of the castle stuff and some of the forest stuff, but that's the most of it. I actually found a few of the tiles arranged, but I did most of them. When I say some tiles were already arranged, I mean that maybe the houses floor and walls were already put together. Arranging them was the hardest part, though.
I mostly organized them like this for Game Maker. You can choose to split it into 8x8 if you want to.
Helios, I'm pretty damn sure darkworld is in there. Which darkworld tiles are you looking for?
It may be missing some animation tiles, like water/waterfall. I'll get them in there, though, if someone can find them for me. I really just can't rip animation tiles, hehe.
I'll convert them to png. Can GIMP do this though? I don't know of a program that can do this.
Finally, I don't need credit. I didn't make any of these, and all I did is mostly put them together. Of coures you can credit me, but you don't have to.
