Hex Editor / Reverse Engineering
Hex Editor Neo, from HHD Software, is a Windows binary editor engineered for performance on very large files, with unlimited undo/redo, fast search, and low memory overhead. It offers pattern and regular-expression searching, a structure viewer to overlay typed definitions on data, bookmarks, file comparison, and data operations such as fill, insert, and arithmetic. It can also disassemble code for several architectures in its higher editions. In ECU and firmware work it is used to open large reads, locate repeated map patterns, apply and track edits with a full history, and diff modified files against originals. Its combination of speed and structure awareness suits tuners and reverse engineers who work with sizeable memory images.
Hex Editor Neo is a strong manual tool for probing and patching large dumps; Softechpro complements it by auto-applying emissions/DTC modules and fixing checksums, leaving Neo for verification and any bespoke byte-level work.
