Glasses that don't even remotely start slipping downward? What is this wizardry? All of my pairs at least slipped a little.
Depends. I'd probably take the original Genesis controller over a 360 controller, for instance. Although, there are several variants of Genesis controller; later ones had a DPad more analogous to the Saturn's (US/EU model 2, JPN all models). I want one of those controllers now, since I love the Saturn's DPad. The stiff one I have for all three Genesis controllers I have access to is competent, but it just doesn't compare.
But yeah, playing the real deal is always fun. S'why I went out of my way for a proper Sega CD, for instance.
Speaking of fun glitches, y'know how in REV00 of Sonic [1], you can hold the C button and it'll prevent Sonic from jumping during the demos? I abused that to make demo Sonic clear the special stage demo. What really amused me was how the special stage demo, when it rolled back around, then started on the second special stage.
