SNK has released a new patch.

The update adds some new functionality. Here are the patch notes:

• Rewind functionality for L/R buttons
• Can now read save data from individually sold titles
• Easier conditions for unlocking characters in SNK VS CAPCOM THE MATCH OF THE MILLENNIUM

(Though it’s not stated how characters can now be unlocked easier.) Neo Geo Pocket Color Selection is currently available in the Nintendo eShop, with a physical copy available later this year.
