| `--chart <路径>` | 直接给 `.ma2` 文件，如 `.../music/music000008/000008_03.ma2` |
| `--game <目录> --music-id <ID>` | 给游戏目录（`Sinmai_Data`、`StreamingAssets`、`A000`、`music` 都能认），按 `musicid` 自动找谱面 |
`--difficulty basic|advanced|expert|master|remaster`（也接受 0~4），默认 **master**。
`--level` 只用于显示（如 `12+`），不参与计算。
### 难度（--level）
难度用**游戏里规定的数字**表示，也就是谱面文件名后缀 `_00` ~ `_04` 的那个数字
（对应游戏主数据 `musicDifficulty/MusicDifficulty00000X` 的 `<id>`）：
| 数字 | 难度 | 谱面文件名 |
| --- | --- | --- |
| 0 | BASIC | `<id>_00.ma2` |
| 1 | ADVANCED | `<id>_01.ma2` |
| 2 | EXPERT | `<id>_02.ma2` |
| 3 | MASTER | `<id>_03.ma2` |
| 4 | RE:MASTER | `<id>_04.ma2` |
`--level 0` ~ `--level 4` 或 `--level BASIC` / `ADVANCED` / `EXPERT` / `MASTER` / `RE:MASTER`
（大小写随意；`--difficulty` 是同一个参数的别名）都行，**默认 3（MASTER）**；
不给时会在 stderr 提示用了默认值。
注意：这里的「等级」指**谱面难度**。谱面的数值等级（如 `12+`）是另一回事，
由 `Music.xml` 自动读出，只用于显示。
## 正向：已知判定数 → 达成率 + DX 分

python chart_achievement.py --chart "<...>\000008_03.ma2" --level 12+ --cp 290 --perfect 8 --great 3 --good 1
