Blades of Steel

Tested using 'Virtua NES 0.71ae' for Windows which you can get from Virtua NES Homepage (works fine in XP), the sites in Japanese but there is an English version of the emulator.
This is a very poor Ice Hockey sports sim which has some nice interlude animations during the second quarter break. One of these is a very small Gradius game interlude, also advertising Contra and Jackal.
This game is also on the arcade but I don't know if it has the same interludes as I found the game quite crap to play and I never got that far.
