+If you want to know what specific hacks MPF used prior to config version 6, see the
 "What were the hacks?" section below. But if you just care about updating your YAML files,
 here's what you need to do:
 
 1. Find and replace `#config_version=5` with `#config_version=6`.
 2. Find and replace `#show_version=5` with `#show_version=6`.
 3. Find and replace `: +` with `: "+`. You'll need to also add the quote to the end of the line. Or if you only have a few different values, you can find and replace the entire line, like `time: +1` with `time: "+1"`, `time: +2` with `time: "+2"`, etc.
 4. Search for any value that starts with a leading zero, like `: 0` and then see if it only has digits after the zero. If so, add quotes around the value. e.g. `: "000066"`. If this is a multi-part value, put quotes around the whole thing: `number: 0804-1` becomes `number: "0804-1"`. This also applies for key names: `0804:` becomes `"0804":`.

 That's it! Not too bad overall. We updated several configs for complete and mature machines, and
 each machine's entire bundle of configs and shows only took a few minutes. It's really pretty quick.

+## How to update your high score data file
+
+If you use MPF's High Score mode, your high scores (and other achievements) are stored in a YAML file. The format of that file has changed in config version 6. Here's how to update it:
+
+1. Find your high scores file. It will most likely be in your machine folder, in the data folder, and it will be named `high_scores.yaml`.
+
+2. Make some changes. Here's what an old high score file will look like:
+
+``` yaml title="Old high score file"
+
+bonus_rupees:
+- !!python/tuple
+  - WIZ
+  - 146
+- !!python/tuple
+  - AAA
+  - 126
+score:
+- !!python/tuple
+  - WIZ
+  - 563550
+- !!python/tuple
+  - WIZ
+  - 537200
+- !!python/tuple
+  - WIZ
+  - 510630
+- !!python/tuple
+  - WIZ
+  - 482705
+- !!python/tuple
+  - AAA
+  - 458435
+- !!python/tuple
+  - WIZ
+  - 449960
+
+```
+
+3. Delete the `!!python/tuple` from each line. (You can do this with a find and replace.) However you want to keep the dash, so your new file will look like:)
+
+``` yaml title="New high score file for MPF 0.57"
