The Tavern

I have tried changing every way in the tiles_options file that I can to make crawl_tiles run in fullscreen and at a lower resolution.
My eyesight is pretty poor and is getting worse and I wanted to make the game run fullscreen at 800x600, but no matter how many times I change tiles_options, it doesn't do anything at all.
The game runs fine, but it always opens up in a window that fills up most of my screen and the tiles are always the same size.
I've even tried increasing the tile size, but that didn't do anything either.
No matter what setting I change, it never seems to take.

I'm running windows 7, if that makes any difference and the newest version of dungeon crawl stone soup.

The full screen option uses your current desktop resolution. It won't change your resolution before starting the game. To do that, you'd need a custom shortcut or maybe a batch file of some sort.

I can't even make it go to fullscreen in the first place!
It won't go to fullscreen at all, it only wants to open in a window.

# tile_full_screen = true
# tile_window_width = 1024
# tile_window_height = 768
# tile_map_pixels = 3
# tile_force_overlay = true
# tile_layout_priority = minimap, inventory, gold_turn, command, spell, monster

make sure you remove the # before every line you want to use. Otherwise it's just commented out. That goes for all configuration files.

I added
tile_full_screen = true
tile_window_width = 1024
tile_window_height = 768
The game plays fullscreen but it keeps desktop resolution, any suggestions?
thanks in advance

Instead of changing the window size, you could change the size of all the display elements,
This increases the size of most of the things in the display

tile_filter_scaling makes the scaled-up tiles smoother, I'd play with whether you like that on or off, you can play with all the other numbers until you get it looking the way you want.
(There's also a tile_font_*_file if you want to change the font face of the text elements)

thanks
