While in ver. 0.01a of Unfinished Dream of All Living Ghost, Seiran’s dialogue with Marisa was identical to Nazrin’s dialogue with Marisa (see /post/719143530161979392/ for side by side screenshots), in ver. 0.02a Seiran’s dialogue with Marisa was completely changed (this also includes different facial expressions for some lines).

For reference, left side pictures are from ver. 0.01a and right side pictures are from ver. 0.02a.

In ver. 0.01a of Unfinished Dream of All Living Ghost, Seiran’s dialogue with Marisa is identical to Nazrin’s dialogue with Marisa.

During Seiran’s story mode, one of Nazrin’s dialogue line was slightly changed in ver. 0.02a of Unfinished Dream of All Living Ghost.

0.01a: 幽かにお宝センサー反応している
0.02a: 幽かにお宝センサーが反応している

The additional text from the description of Aunn’s けしかける狛犬Unleash the Guardian Hounds ability card has been removed in ver. 0.02a of Unfinished Dream of All Living Ghost.

This was most probably a leftover description from 100th Black Market.

Seiran’s name was wrongfully written as Nazrin in ver. 0.01a of Unfinished Dream of All Living Ghost. It has been corrected in ver. 0.02a.

Tewi Inaba’s spellcard background from Phantasmagoria of Flower View and Shoot the Bullet has a frog with the same pose as the one from Suwako Moriya’s dress.

Reisen Udongein Inaba and Tewi Inaba use the same spellcard background in Imperishable Night. Previously, I had the impression that the moon position was different, but it was because the moon was moving. So there is no difference between their backgrounds.

In Phantasmagoria of Flower View, Tewi had her spellcard background completely changed, which she also used in Shoot the Bullet.

In Double Spoiler and Impossible Spell Card, Aya Shameimaru’s and Hatate Himekaidou’s spellcard backgrounds are identical to eachother. Momiji Inubashiri’s spellcard background is also very similar, although the colours are a bit different.

Aya Shameimaru had a different spellcard background in Phantasmagoria of Flower View, but it has been changed in Mountain of Faith and has remained the same since (see Double Spoiler and Impossible Spell Card appearances).

In Shoot the Bullet, you fight Aya during 審判「浄頗梨審判 -射命丸文-」 Judgement “Cleansed Crystal Judgement -Aya Shameimaru-” spellcard, but that is Eiki’s spellcard, so that’s why it looks like there is a different background.

The textures from Mystia Lorelei’s spellcard background are barely moving in Phantasmagoria of Flower View compared to Imperishable Night.

Yukari Yakumo’s spellcard background uses her appearance from Perfect Cherry Blossom, where she had the outfit with red ribbons.

In Imperishable Night (as opponent), Shoot the Bullet and Impossible Spell Card she has the outfit with blue ribbons, but the background is still with red ribbons.

Yuyuko Saigyouji’s spellcard backgrounds from Perfect Cherry Blossom until Violet Detector.

In Perfect Cherry Blossom and Imperishable Night she had the same background, but in Shoot the Bullet, although the background uses the same textures, it seems that the coloured effects are behind the tree and not overlayed on it.

In Ten Desires, the textures were updated and you can also see that the final output is different. The tree bark is not visible anymore and the coloured effects are moving slower.

In Impossible Spell Card the textures have slight adjustment of hue and saturation, which remained the same in Violet Detector, but interestingly enough, the final output from Impossible Spell Card looks pretty much the same as in Ten Desires, but in Violet Detector the coloured effects are more emphasized.

Violet Detector spellcard background seems to behave like the one from Ten Desires trial. You can find a gif of that in one of my older posts: /post/165910660494/.

The following post is intended to be a reference about what backgrounds are displayed during the spellcards which have two characters in Violet Detector.

Nightmare Diary
Yukari, Sumireko - Doremy

Last but not least, Yukari also has her background present in the game files, but she doesn’t use it anywhere during the game.

Below are screenshots from the extracted folders which contain the unused backgrounds. Side note: yes, Mokou’s phoenix can also be found in the files, but she doesn’t use it.

When analyzing Alice Margatroid’s spellcard background from Imperishable Night, I noticed that the texture which is spinning counterclockwise looked like the texture from Wriggle’s background which is slowly moving downwards.

However, upon further investigation, it seems that the texture is the one which appears in Sakuya’s spellcard background and not the one from Wriggle’s. If you take Sakuya’s texture (left side) and compare it to Wriggle’s texture (right side), you can see they both derive from same initial image (hence the similarities), but now they are two different textures.

Also, while still on this topic with this particular image, Yukari Yakumo’s spellcard background contains it, but this time it is not a separate texture anymore, it is part of the image with Yukari.

And regarding Yukari’s spellcard background, it seems that it has the same motif as the jewel case cover of the Perfect Cherry Blossom CD. Although the positions do not perfectly match, if you put the two pictures side by side you can see the similarities: Yukari’s pose and the diagonal line.
