Case study

Witch Time: static recompilation of Bayonetta 3

Witch Time is a static recompilation of Bayonetta 3 for Nintendo Switch. It translates the AArch64 code to C from a personal dump and runs it on a reimplemented system layer, with NVN on Vulkan. The dump folder contains exefs and romfs. On Linux, cargo builds tools/wtbuild and wtbuild setup --dump takes that folder. A Windows release zip runs witch-time.exe and needs a Vulkan driver. Gameplay is 60 FPS in the tested Tokyo and Shibuya sections. The default resolution is 1600x900. The Old Picture Book uses update program 1, title ID 01004A4010FEA001, update 1.2.0, placed in program1.
