 Our goal is to eventually make DOSBox-X a complete DOS emulation package, both fully-featured and easy to use, and give the users all the options to configure the DOS virtual machine. We implement new features with each official release, and also try our best to deliver a consistent cross-platform experience for users instead of focusing on a particular platform. In order to help improve the general DOS emulation and also to aid retro-development, it is our desire to maintain and implement more accurate emulation, but at the same time we are also making efforts to improve emulation quality, speed, and usability for end users. Furthermore, we hope to improve the out-of-the-box experience for new users who want to run DOS programs or games.
