Homebrew developer Sephiroth_FF7 just released a quick update of GhostBustersDS for the Nintendo DS. Unlike previous builds though, this version 0.4 does more than squash a bug or open a door. You'll still be defending New York from ghosts, but this time, it's made easier since you can cancel purchases and corner those pesky phantoms.

Aside from a handful of gameplay changes, a new boss fight has been added and ghosts don't get paralyzed anymore when they hit others. A bug that acted up when accessing bank accounts has also been fixed. Here's the roughly translated changelog:

• Addition of the combat against Grozer
• The keys of the keyboard do not remain red any more
• Possibilities of cancelling the purchases of objects
• The phantoms can be caught on the end of the ways
• The phantoms are not paralysed any more when they are touched by the emanations
• Correction of a bug concerning the banking accounts
