This patch enhances the adult-oriented features of the Steam version of Purino Party. Specifically, it expands the variety of CG images you can unlock to view in the Gallery section.
Copy the "xrated.FLT" file into the folder in which Purino Party is installed. You can locate the Purino Party installation folder via the Steam client by opening the Local Files tab in the Properties window for the game and clicking "Browse Local Files...".
To uninstall the patch, simply delete the "xrated.FLT" file which was previously copied to the Purino Party install folder.
NOTE: Please close Purino Party before attempting to install or uninstall the patch. Save data is unaffected by installing or uninstalling the patch.
When the patch has been installed successfully, the title screen for the game will change to say "X-RATED".
