Help Understanding RPCS3 Compatibility List Data Mapping

The patchsets data comes from the PS3 updates API as-is, we don't modify the data other than importing it as XML and exporting it as JSON. This data is completely optional and it's only used by the emulator to display if an update is available, or to display changelog information when installing a package, if available. This data is not used in any way by the compatibility list other than displaying the list of available updates, when you click a table row in order to expand it to show update information.

Game titles are not exported through that API since it's data meant for emulator usage where the game title is already present. There are several other fields in the database such as wiki page ID, forum thread ID that are not exported since it's data the emulator doesn't use.
