This is Version 3.5 of the PTTG Tileset. 

For a general install, please extract the zip file into the top of your Dwarf Fortress folder. I don't know how this will interact with existing graphics tilesets, but if you have installed those, I don't need to tell you how to install mine.

STANDARD
35a is the standard no-graphics, full-size tileset. It is 16x16 per tile, and the best settings for it are as follows; you can paste this directly into your init folder:

[WINDOWEDX:1280]
[WINDOWEDY:400]
[FONT:PTTGV35a.bmp]

SMALL
35_12x is the smaller, 12x12 per tile font for smaller screens/office mode. It has been scaled down from the original and won't look as good, but can be used normaly.

[WINDOWEDX:960]
[WINDOWEDY:300]
[FONT:PTTGV35_12x.bmp]

GRAPHICS MOD (Advanced)
35b is nearly the same as 35 a, but it is designed so that when a corpse of any of my graphics-set races reverts to it's basic tile, it will look like a skull instead of a letter. Install both tile and graphics sets normaly, then go to the standard creatures Raw fill and change the charicter letter for Humans, Elves, Goblins, and Kobolds to simply "1", exactly as it is in the dwarf entry. Here are the settings I use for my inits:

[GRAPHICS:YES]
[GRAPHICS_WINDOWEDX:1280]
[GRAPHICS_WINDOWEDY:400]
[GRAPHICS_FONT:PTTGV35b.bmp]
[GRAPHICS_FULLSCREENX:1280]
[GRAPHICS_FULLSCREENY:400]
[GRAPHICS_FULLFONT:PTTGV35b.bmp]
[GRAPHICS_BLACK_SPACE:NO]

Good Luck! See the thread on the Bay 12 Games Fourm if you need more help!
