Intelligentvision released Carl Mueller's DK Arcade last year.

D1K Arcade is a similar, but it is enhanced.

It contains a Japanese mode.....you can play all 4 screens back to back. The control has been tweaked and is improved. The enemy action is more accurate. Some arcade tricks work on this version.......control the barrels.....it has digitized sounds....it has a code for a 30 frames per second mode that gets rid of an issue with disappearing objects on some HD TVs that have trouble displaying the smooth 60 frames per second moving objects.

So, if you own the Intelligentvision release, I would suggest getting D2K Arcade. However, if you own neither, you should really pick this up.
