+      **Please read before creating a new bug report:**
+      1. Make sure there is not already an issue for this bug by [searching in **both** open and closed issues](https://github.com/stenzek/duckstation/issues?q=is%3Aissue+sort%3Aupdated-desc+).
+      2. All enhancements **must** be off. To quickly disable all enhancements with affecting your normal configuration, you can check **Disable All Enhancements** in Advanced Options.
+      3. All advanced options **must** be at their default values.
+      4. No cheats may be active. If you were using cheats, they should be disabled, and the game must be rebooted before reporting the bug.
+      5. Do not share save state files. (Sharing memory card files is OK.)
+      6. Verify your BIOS and game dumps, as we can not assist with issues resulting from bad dumps.
+      7. If playing PAL region software, please check whether or not the game has LibCrypt protection. If it does, make sure you have a [correct SBI file](https://github.com/stenzek/duckstation#libcrypt-protection-and-sbi-files).
+      8. Please post your bug report in English, as this is the only language spoken by the developers. The [Discord server](https://discord.gg/Buktv3t) has many helpful people if you need help translating.
+      9. Issues about the libretro core will be deleted (you will be blocked from the repository if you create such an issue). That core is not DuckStation, it is a broken fork, and has nothing to do with us.
