Autosave during eyecatch

While a real autosave (either time-based or number of line based) might be difficult, it should be pretty easy to force a save to a particular slot (a non-user saveable slot) during/after every eyecatch (when the umi logo appears and the glass crack effect is shown).

在遊戲程式碼中尋找 eyecatch 觸發器，很可能在場景或 UI 管理器中。識別儲存資料的處理位置，並找到一個寫入非使用者槽位的函式。透過觸發一個 eyecatch 並驗證自動儲存是否在不中斷遊戲玩法的情況下發生來進行測試。
