Static gba::builtin_art::CGA_8X8_THICK

pub static CGA_8X8_THICK: [u32; 512]

The CGA Code Page 437 type face, with thick lines.

There’s 256 tiles, packed down to 1bpp.

To easily decompress this you can use the Cga8x8Thick type, which provides a safe helper method:

Cga8x8Thick.bitunpack_4bpp(CHARBLOCK0_4BPP, 0);

I am not a lawyer, but type faces are not protected by copyright in the USA. The copyright status of font faces varies by country. If it matters, CGA was first released in 1981. This 8x8 version comes from the Dwarf Fortress Tileset Repository.
