The CD+Graphics specification forces us to use their 288x192 resolution with 16 colors maximum. However, some of the colors are assigned and cannot be used for graphic colors (i.e. Background, Border, etc).
Thus, your request for better graphics, and our requirement to comply to the CDG spec prevents us from creating a CDG format song with a higher resolution.
MTU is working on something for the future, but we are not ready to reveal this.
