只有savegame.sv有用，备份存档时可随意修改名称；
When you make a copy of your save, just change the filename.

用https://www.saveeditonline.com/打开存档，拖拽上传即可；找到BALLS_TYPE条目，0对应故事模式，1对应挑战模式，2对应铁人模式。任意模式打到第34关（保险起见，建议用挑战模式），之后在这里换别的模式过关，即可拿到不同模式通关的成就（“回家”，“挑战完成”，”钢铁意志“）。

Upload your save to https://www.saveeditonline.com/, find the item "BALLS_TYPE", 0 - Story Mode, 1 - Challenge Mode, 2 - Iron Mode. Go to level 34 (best with Challenge Mode to ensure your scores), then switch modes and complete the level, you will get the mode-related achievements ("Home Sweet Home", "Challenge Completed", "Iron Will").

存档里还有很多内容可以修改，但改多了可能会出bug，建议谨慎操作（来自一关关打完铁人的冤种的忠告）。
There‘s more you can edit, but it may cause bugs, proceed with caution.
