This music cart for the NES was released in 2016 on Nintendoage with profits donated to the website. There were (40) CIB and (29) loose carts produced.
From the publisher:
"The cart itself contains 20 public domain Christmas songs, reimagined and done to perfection by humanthomas. I think you'll all really enjoy what he's done. There is an image on the screen just for something to look at while you listen, and it changes every other song. Sorry, no real "game" involved here. Just music! Track list below:
1. Jingle Bells
2. O Come All Ye Faithful
3. Deck The Halls
4. We Three Kings
5. Hark! The Herald Angels Sing
6. Away In A Manger
7. O Little Town Of Bethlehem
8. Up On The Housetop
9. Joy To The World
10. Angels We Have Heard On High
11. First Noel
12. What Child Is This?
13. O Holy Night
14. God Rest Ye, Merry Gentlemen
15. Silent Night
16. Wassail Song
17. I Saw Three Ships
18. It Came Upon The Midnight Clear
19. Jolly Old Saint Nicholas
20. We Wish You A Merry Christmas"
More Detail:
- Christmas themed art is displayed on the screen while the music plays with a track time. Left and right on the d-pad changes the track being played.
- The cart shell is two colors, one for the front and one for the rear. These were assembled at random between translucent red and translucent green.
- At least one has been modified with internal blinky lights by the end user.
