There's a new hex editor in town
There's a new hex editor in town: Hex Fiend by Peter Ammon (aka Ridiculous Fish). It basically seems to do everything my old friend HexEdit does, except for opening the resource fork of a file and for the disassembler, which I didn't use anyway.
Also, HexFiend is a Universal Binary, so I'd guess one would much rather have an Intel disassembler.
The town's getting bigger - recently I published Synalyze It! which is not only a Hex Editor but has some advanced features for the analysis of binary files (of unlimited size).
Please have a look and give me feedback :)
