Yarudora Series Vol. 2: Kisetsu o Dakishimete

To unlock the Completion Rate Display, an useful tool to help achieving 100% Completion Rate, as it allows to see in real time your Completion Rate progression as you go through new paths and scenes, input the code below. If successfully input, a chime like the one heard when selecting the options at the Title Screen will ring. The code only works with the animated "Production I.G." screen (appearing only on start-up, or after a soft-reset); so if you fail inputting it, either press the Reset Button of your console, or use the Soft-Reset command and try again. The Completion Rate Display can be toggled on/off by pressing the Select Button during the game.

To unlock the Hint Marker, which points you out the good choices during the answers prompts, get at least two Bad Endings, without getting a Good or a Normal Ending beforehand, and restart the game from the option "Tsuzuki kara" (Continue). Be careful: If you get a Good or Normal Ending before unlocking the Hint Marker, the Hint Marker will no longer be unlockable.

Depending on the number of Good Endings you get, the background picture at the Title Screen will change. There are 3 unlockable background pictures:

Those trailers for the other 3 games in the Yarudora series will be viewable immediately after finishing a playthrough with a Good or a Normal Ending. From the 4th playthrough and on completed with a Good or Normal Ending, you'll be able to choose the trailer you want to see. Also, once unlocked, the trailers can be viewed during Attract Mode, if Disc 2 is playing.
