The roms on this bunlde where never extracted right?

The bundle has the english version of:

Nekketsu Renegade Kunio-kun
Nekketsu High School Dodgeball Club
Downtown Nekketsu Story
Nekketsu High School Dodgeball Club - Soccer Story
Downtown Nekketsu March Super-Awesome Field Day!
Downtown Special Kunio-kun's Historical Period Drama!

Surprise! Nekketsu New Records! The Distant Gold Medal
Nekketsu Fighting Legend
Kunio-kun's Nekketsu Soccer League

And all of them are enhanced with improve performance and response, for example Double Dragon 1 has less input lag, less flickering and fixed bugs.

Another anon said they weren't NES ROMs.
