KillerMan: Ghost Buster is a hombrew game for Nintendo 3DS by Greiga Master. You play as KillerMan from MegaMan Battle Network 6 and fight off waves of ghosts and viruses to try to get a high score. The game features stages where you fight sets of viruses and an endless mode where you test how long you can last against an endless wave of ghosts and viruses.

Changes:

* Uses romfs now so you can get rid of that assets folder and expect faster battle load times
* Using DSP instead of CSND for audio
* Removed deprecated GPU functions
* 3D effect with slider
* Fixed ranks not moving around correctly when getting new top score
