Sega Saturn interesting finds

Been playing with a real Saturn today, and confirmed that the glowing spheres ring issue occurs there too. You can see a couple of rings above you at the start, but by the time you get back up there, they're gone. At the top, some rings mysteriously appear, and if you then fall down again, the others are back.

Also, the NTSC-J version seems to have a much more serious bug: the snow never stops falling after either boss in Icecap. This causes serious object loading issues of the kind in ORKAL's video, and it's fairly easy to get into a situation where you can't complete act 2 or have a seriously difficult time doing so - so I guess this proves that while the VDP sprite limits aren't an issue any more in Jam, the object RAM limits are still very much in play. This is fixed in the NTSC-U/C version, and I assume the PAL-E version too, though I haven't tested it.

This is all from a fairly quick test too! I wonder what other nastiness lurks within. Seems strange to think this is sometimes regarded as the "best" version...

 

I have the sonic Jam moldels, Just found them on my hard drive.
However there are no UV unwraps , and everything is a real mess.
maybe I will clean them up and make a release.

however first we would need all the textures lol.
Edit: I started ripping some textures for buildings and such from VDP1

 

Don't remember seeing this bird in Jam.

Anyone care to check? My Jam CD is packed away and I'm to lazy to find it right now.

 

Here are some other strange objects I just cleaned up.
I don't think we will be able to rip the textures for unused models using an emulator.
must be another way to extract the files from the game disk.


Also Uv mapped and re-textured these by hand.

 

...Pig Picky and Flicky heads?

 

Sorry, I got them from SANik some years back.
You may want to contact him.
I also have the sonic model. Its in pieces though.

Edit:
When I'm done with the tedious clean up, and re-texturing than I can post it up here for you guys.

 

Captured the parts that were clipped off in Sonicstudiums screen.

It looks like we wont be able to capture all the VDP2 textures with Satourne. There has got to be another way to view the remaining missing textures.
Anyways,,,,That's it for me today, I cant go on any longer.
DOWNLOAD NOW!

 

Ahh man,, what a shame......
Anyhow I have most of the level textured already, cant wait to be able to get my hands on the rest of the ground textures.
may be able to finish working with what I have tomorrow.

Also it while playing the game it looks like they combined vertex colors in a blend with some of the textures to simulate lighting. (if your viewing on a Saturn its noticeable)
some emu's don't show this effect.

 

This is a bit off topic here but I found this blender script that can export Saturn format models. perhaps it can be of use to someone here at retro.

Maybe... it could be reverse engineered to import Saturn models into blender?

 

Okay guys , Here is your Jam model. ( sorry did not get to this sooner, was working on AXSX stuff.
Credit and many many thanks to SANik for his model rip that I found on some forums a while back. (can't remember where, as its been many years.)
Without him this wouldn't have been possible.
And credits to myself for the polygon clean up, UV mapping, limb re-positioning, Texture ripping and placement, and old-school rigging.
Enjoy!


Now if we can get the rest of the textures ( the ground textures) I will release the rest of the models fully texture-mapped and cleaned up.
Including some that had to be built from scratch, since they couldn't be found anywhere else.
Everything is already finished and ready to go except the ground.

( the tease)

 

OHHHHH, If you can get the playfield fully ripped, I'd be happy to port it to the source engine. The Sonic Jam play field looks perfect to be a sonic themed build or Roll play map.

 

lol that would be cool, but without the final VDP2 textures it will stay unfinished unfortunately.
I Was hoping that I could coax one of our many Sonic retro Super-Hackers (tech members) to do the job, but none have bit. Its a real shame.
You guys call yourself hackers ?! (Shakes finger) Why not jump in and explore new grounds ? We've seen enough Genesis game hacking.

(Off topic)
Imagin making A sonic Jam hack featuring new levels. Now that would be kick ass. but yeah , Everyone is stuck doing generations mods these days. Where is the challenge in that ?
( I'm being sarcastic by the way)

 

If I may ask, what it the render setting of the emulator? Open Gl? a version of Direct X?

 

for Yabause its Open GL. It also has a choice for software rendering.
