B2P - ChunkEdit is a simple, GTK-based binary file viewer and editor built using C++. It allows you to inspect and modify files in fixed-size chunks, either in a structured grid layout or as raw hexadecimal text.
This tool is part of a planned broader Bin2Play (B2P) toolkit. (This is just the first concept)
- ✅ Open and read any binary file
- ✅ View file contents in chunked format (custom chunk size)
- ✅ Edit binary data in two modes:
- Grid view — edit each byte individually with a tooltip showing the file offset
- Raw hex view — edit the full chunk as a hex string
- ✅ Navigate between chunks with Prev/Next buttons
- ✅ Adjustable chunk size (1 to 4096 bytes)
- ✅ Save changes to a new file via "Save As"
- ✅ Chunk-level tracking to ensure only modified parts are written (Flawed in several ways) Flaw 1 - First off if you edit a chunk, you have to save the file while in that chunk, this is not how it's intended to be. Flaw 2 - When switching between RAW/GRID it will reset what you changed, not intended to be this way, which means if you edit in RAW - Save new file before switching, same with GRID.
