Somehow, they managed to improve Major League Baseball! (Well, fly balls, sliding into base, etc.)

World Championship Baseball (a.k.a. All Star Major League Baseball) is a godsend for those without a pal to play the original Major League Baseball against. The original baseball still plays well - and this goes right along with it. The additions of some scrolling to the outfield and the cloud of dust when sliding into base (another new feature) are great. Even the sprites for the players have been modified somewhat from the originals.




ROM No ROM variants have been identified.
Box So far, two variations have been found.
Manual Three variants have been identified.
Overlays Four different overlay variations are known to exist.
Label To date, two labels have been recorded.
Easter Eggs No known Easter eggs exist, but there are bugs than can crash the game.




A total of two World Championship Baseball box variants have been documented.

Image Vendor Part Number Year Origin Description
World Championship Baseball Box (INTV Corporation 5789) INTV Corporation 5789 None   DOES NOT have the 'FOR 1 OR 2 PLAYERS' text on front of box; no origin or copyright date; game title and Intellivision® logo on bottom flap—title is upright when box lays face-up; part number was originally assigned at Mattel for this one
World Championship Baseball Box (INTV Corporation 5789) INTV Corporation 5789 None   FOR 1 OR 2 PLAYERS on front of box; no origin or copyright date; UPC bar code (right side) and game title on bottom flap—title is upright when box lays face-up; part number was originally assigned at Mattel for this one

Special thanks to Hankster and Scoubidou for pointing out that game title vs. UPC variations on the bottom flap of the box exist. My theory on this is that the earlier copies of the game had the game title only. Later copies, destined for store shelves, added the UPC barcode. Note that the barcode has the digits 05789 at the end - 5789 was the catalog number of World Championship Baseball. I suspect, based on games in my collection that also exhibit this phenomenon, that there is a correlation between the presence of the UPC and the 'FOR 1 OR 2 PLAYERS' text on the front of the box for some games. I've also seen this for Bump 'n' Jump and Pac-Man, but not on Motocross (yet). Other games with the UPC variation include Tower of Doom and Super Pro Football.

Title Screen Title screen for World Championship Baseball.
Field of Dreams The puff of dust is a nice touch. Fly balls, etc. are all good enhancements. Were these early 'upgrade' releases the kernel of the idea of the current trend with sports titles, which now ship an upgrade each season?
