You seem to have a lot of knowledge about the Saturn, what games did you programmed? :)

It happened while playing fighting vipers and megamix. Both am2 games. Well, those bugs got fixed with updated dsp emulation, so I guess, they both used it..

Actually, in early emulators, with incorrect SCU DSP emulation, while playing AM2 fighters, you can experience several 3d errors, like flying to the other side of the ring when punched.. That means it was used, yes.

Im not a programmer, but from all the interviews, Saturn it actually more powerful (raw) than the PS1. But: Poorly designed CPU cache and RAM access, makes it hard to properly take advantage from the dual-cpu. As for the DSP, its even harder to syncronize with the dual SH-2's, and needs to be...

Most of the floor is rendered by the VDP2. Most of it is flat. Only the river section the small undulated sections (the small bridge, river, and central island) are rendered via VDP1. Go and try it on an emulator..

Trees are 3D. Trunk is flat, but the branches are polygons, 100% sure. Shame im under 10 posts, and cannot post links or pics. Sonic Jam floor is definitely rendered by VDP2. You cant compare Crash Bandicoot to Sonic Jam. Crash is only a very narrow corridor, very different from the open 3d...

Trees are 3D. Im not stating the Saturn was technical superior to the other systems.. But some particular games, designed to take advantage from the VDP2, would be impossible to run on other systems without downgrading.

VDP 2 can draw a128x128 flat floor at 60fps. That's 980k "polygons" / second.. Im not stating that the Saturn was more powerful than the PS1/ N64, but some games designed specifically to run in it, would have been impossible on the other systems, without pop-up or reduced texture resolution...

Well.. have you tried the game? The top default view is not impressive at all, but if switch to back view, you can actually see all the level geometry up in the distance, fully textured. Moving objects are gourard shaded. Floor is flat, but fully textured too, no pop up at all. Solid 30fps...

There are a couple of games that would be impossible to render with such quality (textures) and effects. Sonic Jam, with beautiful textures, no pop-up at all (except sprites), and huge 3d view.. Very good use of the VDP2 to render the flat floor, coupled with very wise use of polygons to render...

Hi there. Its my first post on this forum, but I follow the discussions for 4 years now. Im not a programmer, my only experience developing games, was back in the high school, tech demos for the mighty TI-83 :D Im from Portugal, and SEGA was big there. Until 1998, Saturn outsold the PS1 by a...
