+A 64K ROM image is supported. As there were many areas of $00 and $FF 
+bytes in RomWBW, it is possible to compress the 128K RomWBW *.upd file 
+to fit into 64K ROM. The compression routine looks for two or more 
+consecutive bytes of the same value (any values of $00 to $FF). If it 
+finds duplicates, it would leave two duplicate bytes followed by a byte 
+count, n-1, (with a max byte count of $FF) where n is the total number 
+of duplicates. 
+
+A stand-alone program written in C creates a ready-to-flash binary file 
+for the 64K ROM. The 64K binary file is in the following format. Layout 
+of the 64K ROM:
+
+* The first 3 bytes are always $C3 $00 $FF, a jump to the Z80 
+  decompression code located at $FF00 in the ROM.
+
+* Locations $0003 up to, and including, $FEFF are then available to 
+  store the compressed 128K *.upd file.
+
+* Locations $FF00 up to $FFFF, a seperate Z80 decompression routine that 
+  executes at startup to decompress the the 64K ROM into RAM.
