Case study

Ottsel: an ARM64 port of Jak and Daxter

Ottsel ports OpenGOAL's decompiled Jak and Daxter: The Precursor Legacy source to iPad, iPhone and Apple Silicon Macs. It adds an ARM64 compiler backend, ahead-of-time signed modules and an Apple-platform app with touch and controller input, while extracting art and data from the user's PS2 disc. The author reports physical-iPad and Mac runs; physical-iPhone testing remains pending.
