Turbo Grafx 16 / PC Engine Mednafen Sprite Glitch(?) - buddludd - 01-29-2024
This might be a really stupid question. I'm trying to rip the sprites from Tokimeki Memorial, but some of the frames look glitchy and sometimes include colors from the background (After using mednafen to replace the background with solid green)
This might just be how the sprites actually are and the artists just didn't care that much about the animation frames since you can only really see them for a few milliseconds anyway. So maybe this isn't a problem at all and I'm just dumb. I felt it was a good idea to ask though just in case. Is this how the sprites are supposed to look?
Attached are two images. The first has a pixel of the green background on the right side of her bangs, and the second one has a duplicated eye glitch thing going on.

Maybe it's like Princess Minerva, with huge background objects like the girl on your screenshots and then additional overlays for eyes and mouth.
I can imagine that the overlays sometimes glitch out (oversight by the developers) and produce weird frames.
Have you tried the the tile viewer from my tutorial to double check?
Or is there any stuff on the other layers?

The glitches don't appear in the tile viewer I don't think. It's hard to parse with how it's all jumbled up in a weird order though, so I might just not see it. I've attached comparison pics.
And no other stuff on any other layers. I do think it works like Princess Minverva though, yeah.

Can you upload a quicksave from that particular spot in the game (mediafire, mega.nz, etc.)?
I will take a closer look then.

Just a normal save state? Here. Though it happens in many spots, not just this one. Pretty much all the sprites with animation frames are affected in some way, which is why I thought it might just be due to a flaw in the game itself.
Thanks Mr. President.

Apparently, the game renders at a higher resolution and produces artefacts if the window is too small.
Pressing ALT+Enter to view the game in fullscreen mode fixed this for me.

That doesn't work for me. Still have some glitching. They happen in the frames where she is just starting to open her eyes from blinking. Even starting in fullscreen by default doesn't work. Attached are screenshots I took in fullscreen. And these are from starting a new game without using the old savestate, but still the same result unfortunately.

Checked it again, fullscreen only fixes the nervous / missing lines on objects / sprites.
The broken eye tiles on Shiori don't belong in that category and are an oversight by the developers.
The original animation has 4 frames in the tile viewer, but ingame there are 6 frames.

Btw the ingame screencaps are windowed, this is why nothing lines up correctly with the tile viewer (sprite is a bit distorted and some lines on the sprite are missing).
I wasn't able to make screenshots during fullscreen mode, but it should be enough to showcase the eye problem. (edit: I forgot that you can make screencaps with F9)
PSX version looks fine btw (probably a tile rip):

It's too fast to be noticable, so maybe this is why it wasn't discovered during development.

Okay thanks! So should I upload the garbled sprites, or just the ones from the tile viewer? What would be the proper etiquette for this situation?
RE: Turbo Grafx 16 / PC Engine Mednafen Sprite Glitch(?) - Barack Obama - 01-31-2024
I would use the ones from the tile viewer, they are actually correct and don't suffer from lag frames.
Some rippers also add the ingame variants to showcase the differences, but that's up to you and your style of assembling a sheet.
