18+ Content

If you have purchased the Steam version of Hello, Goodbye, you can download the free 18+ DLC via NekoNyan website. Download the patch, open the .zip archive file, and extract adult.dat into the HGB_Data in the Hello, Goodbye install folder. You can confirm this is installed correctly by checking the options for an ‘Uncensored H-scene CG’ option. There is also an R18 Patch Enabled notice on the title screen.

Alternatively, you can buy the uncensored version of Hello, Goodbye on websites such as JAST USA.

Steam Achievements

There are a variety of achievements if playing the Steam version of Hello, Goodbye. Aside from clearing routes, you need to do the following to unlock them all:

  • Play the game for 24 hours
  • Clear the minigame
  • Use all of the save slots
  • Quick jump 10 times
  • Quick save more than 10 times
  • Listen until the end of Yukishiro George’s first and second speeches

  • Try out all available window resolutions

If you wish to delete save files after making extras for the above achievement, this can be done easily by going to the ‘1009460’ folder. You can find this under your Steam install folder, which will by default be C:\Program Files (x86)\Steam\userdata\<Your Profile ID>\1009460

One of the achievements of Hello, Goodbye is for a minigame where you need to find the cat Azureal. You can find this under ‘Collection’ from the title screen after completing a route, then on the sidebar.
