The Sega Saturn NetLink League

I find strange videos on YouTube. In the middle of this video, though, I saw a Japanese Saturn controller, and they play two games.

I believe the first one is Daytona (I haven't played it enough to distinguish it for sure). The second... I can't even really guess at. Anyone know what it is? Or what it might be? (Actually, upon closer inspection, I realize that it's a Dreamcast game... but I still don't know what it is.)

the second game looks like die hard arcade (came out on saturn). so it's probably the sequel on dreamcast called dynamite deka 2 (jpn only release).

that first game is def. daytona, but i am also unsure as to which game the second is, if it was for the saturn it looks great
