- In the original PV of "Remote Controller" Rin is holding a Famicom controller (japanese version of NES). Due to the fact that Project DIVA is released on Sony PlayStation consoles and developed by SEGA the controller changed into a SEGA Dreamcast controller with a mic attachment. The logo on the Dreamcast controller in the PV got recolored in the English version of the game to match the logo of the English version of the Dreamcast console.
- In the Meltdown stage, a hidden text texture can be found written in the old Menu font of the Project DIVA PSP games. The text contains lines in several languages like "Schmelzen" which is the german word for "to melt" or "melting" while "Fundición" is spanish for "Meltdown".
One line contains "Enjoy Project DIVA". Another hidden texture shows some kind of music note and the number "02" next to it.
- If you play "ACUTE" on HARD difficulty you might notice that the notes matches the Vocaloid who's singing in that moment. In the beginning there are notes with the blue cross because Kaito's singing while green triangles are shown when Miku sings. Luka got the pink squares while red circles and yellow stars are used in the instrumental part of the song. When two Vocaloids are singing at the same time, then you play a mix of their notes like blue crosses and green triangles when Kaito and Miku sing. In the end part of the song when all three sing together you play blue notes while Kaito's shown on the PV while you play triangles and squares while Miku and Luka are shown.
- While western countries usually have songs by English-speaking artists in the top 50 of karaoke songs, "Senbonzakura" is actually one of the most popular karaoke songs in Japan.
- The hit ratings in the English version (COOL, GOOD, BAD, AWFUL) are similar to the gameplay ratings in Parappa the Rapper.
- In Rin-Chan Now's PV, Miku and Luka's back hands do not hold during the part when they blast off into space. This is most likely due to them already holding microphones so the animation is just made to look like they're holding hands from the front. This also occurs in the Arcade version.
- In "Negaposi✽Continues", the notes will appear based on lyrics(e.g. 'maru', 'aka'=red circle, 'batsu', 'ao'=blue cross, 'sankaku', 'midori'=green triangle, 'shikaku', 'pinku'=pink square, 'migi'=right arrow, 'hidari'=left arrow). It appears on Hard and Extreme mode.

Project DIVA F 2nd
- The main menu of Project Diva F 2nd features a background identical to Glory 3usi9's beginning.
- The PV of "Heat Haze Daze" (Kagerou Daze) is the first one which triggers a whole different PV if you hit or miss the golden star note in the beginning of the song. Even though it's just the second PV which has it's chance time in the beginning, "The Disappeareance of Hatsune Miku" in Project DIVA 2nd and Project DIVA Extend in Extreme difficulty did start with Chance Time, but didn't have a different ending of effect in it's PV.
- Also, if you play Heat Haze Daze, the only notes to appear are X's and O's referencing the bright reds and blues of the original PV and the anime, Mekakucity Actors.

- The DP prices for the birthday cakes have a funny secret in it. For example the birthday cake for Miku costs 20831 DP while the cakes for Rin and Len costs 21227 DP. The price is the result of their birthday month and date + 20000 DP. (21227 = Dec 27th (12 27) + 20000)

- Double scratching the big gold star keeps the normal ending despite completing the Chance Time.
- The returning DLC song, Though My Song Has No Form, is the first PV to have it's original PSP ending to become the alternate ending. The standard ending, if you miss the Chance Time star or double flick it, has a new motion and effects added.
