Research & Development / Viper CTR - 40 floppy disk edition.

« Last post by 黒い灯影 on Today at 12:06:31 am »

Okay, so i finally got my greaseweazle and a floppy drive.
and I made flux-level copies of all 40 disks, and converted them to hdm images.

It’s interesting that the duplication company they used left some metadata at cylinder 80, head 0.
That’s beyond the normal PC-98 2HD disk format, which uses 77 cylinders numbered 0–76. So the metadata sits outside the area a standard PC-98 2HD disk would normally use.

Here's an example:

Code: [Select]

I kind of want to dump my other PC98 viper floppies to see if there is such data present also.
its nothing big, but technically interesting.

Its byte-for-byte identical to the CD-version in terms of game files. nothing really interesting that's different.

Fantastic stuff! If you wanna go the extra mile, you could rip the images from the game itself and work off of that.

Thanks! I appreciate the help, but I’m honestly so bad with technology . I’m on a Mac and I can't quite figure out how to use the links and tools to get the game running. But thanks, tho. I hope to play the game someday

I would say the most jarring part are the Kokiri clothing. They're hyper detailed compared to the Hylian clothing we see in Castle Town.

The large torso and short legs thing has been done for awhile now in the Zelda series.

Thanks! I've been working with some original rough frames from the online art book, but it would still be great to have more sketches or original frames to use as a guide.

Right now, I'm in the process of decensoring this part. The only thing I'm struggling with is animating the fluids, but I'll figure out the pattern soon.I'm actually improving the first one I posted since it was my very first time and, honestly, it didn't turn out that well. I'm fixing the spacing so the movement feels smoother and doesn't look warped. Hope you guys like it!

They look good. I'm impressed you seem to have correctly interpreted what's going on in the bottom one. I remember taking a shot at decensoring it a long time ago and thinking the angles didn't make any sense for how much sack swinging seemed to be happening behind the mosaic, but I can see it now.

For the first two, it could stand to have some slight animation on the girl's part, she looks too stiff there.

Having looked up the RSR cg set on Hitomi, and yeah, it's low quality. Makes me mad, considering the game only uses 256 colors, so there's no need to ruin the image quality by making it worse

Here's a set that's lossless quality -- https://e-hentai.org/g/2926452/a25f2c7b54/

Good job on the decensoring btw.

Thanks a ton! Yeah, that Hitomi one was terrible—I'll definitely stick to the new one you sent. Still working on the rest and hope to have more updates soon.

I recently started a new project uncensoring some Viper GIF games, and I decided to start with RSR. No idea how long it's gonna take me, but I'm gonna give it a shot. What do you guys think of this first attempt? I downloaded some images and GIFs from Hitomi, but the resolution is super low. Still, it's all I've got to work with.

I think Link looks fine, though I can see how people are likening young Link to the Gerber baby. He is quite literally babyfaced.

Zelda though.. I don't really know why she's wearing eye shadow and lipstick when met in the castle courtyard. The Shiek redesign with wisps of hair looks great though.

I don't mind the change in Star Fox designs as much as proportion. Changing Falco's legs to be more birdlike is a good change. But reducing the size of everyone's legs so they have really large upper bodies bothers me more. They look top heavy and incapable of running at a decent speed. Peppy's buckteeth and Falco's prominent beak have also been shrunk despite being key character attributes. And its not just the team members - the Arwing's nose continues to shrink, too. The wing diffusers are now nearly as big as the fuselage, which is completely unlikely original SNES or N64 Star Fox dimensions.
