All Prontos that use CCF format (Including Marantz, Yamaha, and Integra) are mostly Cross Compatable. Only Caveat's are using Marnatz files as they have a larger screen size and sometmes buttons get cut off when imported into Prontoedit.

Of course, Importing Color CCF's into B/W prontos will result in Prontoedit converting the Color CCF into B/W...... You get useable codes out of it, but not usually any buttons.
