The Genesis/Mega Drive and naturally the Sega CD have several games that support the mouse, but you can't just connect any old serial mouse to the system.
Yes, the PSX also has a mouse, but playing Quake II with it is strange. With your left hand, you use the d-pad, L1, and L2, and with your right hand, you use the mouse to aim, fire, and I forget what the RMB does. Works well enough, though. Haven't played any other PSX games that use the mouse myself, but there are lists online, of course.
Though it's already been mentioned, the PS2 supports mice. I used a Microsoft USB optical mouse to draw emblems in Armored Core 2. Had to do it the hard way in Armored Core 1 (and its PSX sequels).

Icons, wallpapers, and typical Oldternet nonsense.
