Farbfeld is a new picture format invented this year. I did not invent the format, but I did write many utility programs for use with it.
This includes a program that can read/write tile sets in PC format ("B") as well as NES/Famicom format ("F8") and GameBoy format ("F"), and others. There are also other programs for converting to/from PNG and other more modern formats too (even Netpbm formats). If there are other formats used by old computers you can suggest them here and/or on the Fossil repository.
