From what i looked on youtube
a video called "All Jaguar Games" by Virtual Gaming Library
i spot many 3d games , which has visually various approaches to 3d graphic.
as Atari Karts it feels like there is 3d gpu or something like that activated for 3d games?
i think Doom and Wolfenstein 3D is done entirely in software mode.
and the games like
Battlesphere, Checkered Flag , Club Drive, Cybermorph, Fight for Life, Hover Strike, Iron Soldier (2), i-war , kasumi ninja (selection hall), SkyHammer, Supercross 3D, Tempest 2000, Towers II, White Man cant jump, Zero 5
So as for dream or not XD, if there is 3D so it possible in future (whenever ) emulation gain upscaling of 3d space like Phoenix emulation Project done it for 3DO games, or bsnes of upscaline mode 7, and Playstation 1 ePSXe with Pete OpenGL plugin, or YabaSanshiro for Sega Saturn, or MGBA for GameBoy Advance.
I think you catch my mind , and what i am thinking of?
