 Speed up game reboots by caching game data. Cache data is stored
 in `data_cache.bin` and can be safely deleted if issues arise.
 
+### LooseDBTables
+Load game tables from `.json` files in `Sinmai_Data/StreamingAssets/DB`.
+Useful for string edits (e.g. translation).
+
+Tables are automatically generated if the `DB` folder does not
+exist.
+
+### MoreChartFormats
+Load charts written in various formats:
+- [simai](https://w.atwiki.jp/simai)
+- srt/szt/sct/sdt (maimai classic chart format)
+
+To use, edit Music.xml to point the chart file path to your chart
+file:
+
+```xml
+<Notes>
+  <file>
+    <path>{filename}.sdt</path>
+  </file>
+  <!-- snip -->
+</Notes>
+```
+
+The chart loader depends on the file extension:
+- simai chart files must end with .simai
+- srt chart files must end with .srt
+- szt/sct/sdt files can use .szt/.sct/.sdt interchangeably.
+
+<details>
+    <summary>Simai caveats</summary>
+
+- **`maidata.txt` is not supported. If you have one, paste the 
+  content of each`inote_x` into their own `.simai` file.**
+- Both `?` and `!` will create a slide without a star note, but 
+  both of them will make the slide fade in (`!` makes the slide
+   suddenly appear in standard simai).
+- `$` cannot be used to create a tapless slide (maiPad PLUS
+  syntax).
+- `$$` is ignored, as star notes only spin when there's an
+   associated slide.
+- `[BPM#a:b]` is not supported for specifying hold time.
+- `` ` `` (fake EACH) makes taps 1/384 measures apart.
+</details>
+
+<details>
+    <summary>SXT caveats</summary>
+
+- Encrypted chart files (`.srb`/`.szb`/`.scb`/`.sdb`) are not 
+  supported. Decrypt them before loading into the game.
+- Since this chart format does not contain timing data, the
+  song's BPM is retrieved by loading the `Music.xml` associated
+  with the chart, **and it is assumed that the chart and
+  `Music.xml` is in the same folder**. The SXT loader will not
+  work if the chart file is somehow in a different folder
+  from `Music.xml`.
