Case study

UltraTears: native recompilation of Tears of the Kingdom

UltraTears builds a native version of The Legend of Zelda: Tears of the Kingdom 1.4.3 for Windows, Linux, and Steam Deck from plain exefs and romfs folders. The romfs tree is about 304,000 files and 16 GB. Windows 10 or 11, or Linux with kernel 6.7 or newer and glibc 2.34 or newer, plus Vulkan 1.3, are required. python tools/setup.py --dump takes the dump directory and writes the game folder under build/. About 40 GB free is listed for setup.
