Ocarina of Time is able to play natively on just about every system system imagineable (pretty sure native PS1 builds exist) Sonic Unleashed, previously an 360/PS3 exclusive, now can be played in ultra wide on PC natively.
Majoras Mask got a recent static deanalyzed PC port and has higher FOS and ultrawide mods.
Perfect Dark for the N64 has a native PC port with ultrawide and mouse and keyboard controls.
These are just a few off the top of my head.
