CHECK THIS OUT!!!
Everyone knows you can plug in your own keyboard or mouse with a ps/2 adapter for the dreamcast , and even some optical mice are compatible even some with a USB adapter.

I had this old Micro Innovations wireless keyboard and mouse set sitting around for years I never used the mouse much but i used the keyboard a lot.
And I had this total control 5 adapter for dreamcast i never used much but i tried some mice i have don't work =\

Both the mouse and keyboard on this work great!! Man Now I just need another adapter so I can plug them both in at once!! =D
