I had written a program which can convert between XBIN, ANSI, MZM, and other formats, including support for doorway mode in ANSI files (most ANSI art programs do not support doorway mode). This could be used together with MoebiusXBIN or other programs in order to convert them to/from the formats that you will use with other programs. (I had also considered to add a DER-based format later, in case of other features wanted to be included as well, such as animations, character set mapping (including mapping to TRON code and to other character codes), etc; however, this might or might not actually be made.)
