unPIC is a Perl script that disassembles Microchip microcontroller's HEX files. This is a powerful tool for all reverse engeneers that creates a well understandable assembly source from a binary file. Creates xrefs, labels, subroutines and much more...
FirmMod will be a binary editor oriented to firmware modification and analisys, that will support data mappings of binary files, read/write of motorola s-record files, raw hex editing, etc. (whislists welcome!)
