Moved this to JCS.

1) Tileset size: width is 320 pixels and height has to be a multiple of 32 pixels (up to a maximum of 3264 pixels for a 1.23 tileset)

2) No idea what you mean with black-white stuff. Perhaps you mean the mask? It's a separate image and doesn't have to have black in it, actually transparent blue is the only important colour: #5700CB

3) I loved to make tilesets too!

4) I want a new PC

5) Making a tileset in paint is never easy

6) To make a tileset: draw an image of the correct size (shown above) with a 256 colour palette and then use JCS to convert that image into a tileset). I'd link you to DTR but I deleted that off my host and don't have a backup copy anywhere. I'd reupload it if anyone has a backup but that's unlikely, it was an old and crappy site anyway

7) I have a tileset I never publicated () because it's not finished and abandoned. It's generally a good idea to publicate your tilesets because then people are able to tell you how much they suck (Fquist is really good at this, I like Fquist because he is honest about suck). While it sucks to have people tell you your tilesets sucks, it's actually a good thing because they tell you what sucks about it and you can get to improve (if not it is BAD REVIEW!!!! and gets removed) on that. Practice makes perfect, it's the only way to make better tilesets unless your name is Blade or Agama, and because your name is not Blade or Agama you're just going to have to go through the process of publicating sucky tilesets like the rest of us until you get it right
