Darksoft's Multi-MVS Features
----------------------------
This cartridge is designed to run any Neo-Geo game be it existing, homebrew or even games you may want to develop.

The cartridge has the following features:
* Compatible with every existing NeoGeo game, homebrew or your own developed Neo-Geo software.
