R9 serializes input calls to address the vibration-related crash. The maintainer reports stable Reborn Career Mode on Windows and Linux on ROG Ally Z1 Extreme.
Reborn Career Mode owner-tested at 60 FPS on Windows and Linux, with no gameplay bugs or texture errors observed in those sessions. Current engine timing stays at 60 FPS; broader validation continues.
Original-game Career Mode still has graphics bugs, including an invisible opponent. Fixes are planned for future builds; R9 primarily focuses on Reborn.
