Make DCSS playable on 4k displays

note, May 27, 2023 on Mitja Felicijan's blog

Dungeon Crawl Stone Soup has a a very small font by default. On a 4k display, it is barely readable. This is how I made it playable.

Make a file ~/.crawlrc with the following content:

# Adjust the sizes to your liking.

tile_font_crt_size = 32
tile_font_stat_size = 32
tile_font_msg_size = 32
tile_font_tip_size = 32
tile_font_lbl_size = 32
tile_sidebar_pixels = 64

To zoom in and out in viewport, press Ctrl+ and Ctrl- respectively.

All the possible options are documented in the Dungeon Crawl Stone Soup Options Guide file.
