A DearPyGui-based utility for interactively mapping executable memory layout — defining sections, assigning module ownership, and visualizing unmapped or overlapping regions.
Designed for reverse engineering, engine analysis, and binary architecture research.
- Define named executable sections with address ranges
- Sections are sorted by start address
- Overlapping definitions are prevented automatically
- Sections may be locked to avoid modification
- Create modules and assign their owned address ranges
- One range per module per section
- Module ranges may be locked
- Supports conflict detection between modules
- Configure global EXE address space
- Sections must reside within EXE boundaries
- Enables top-level unmapped-space detection
The Reports tab highlights integrity issues and unused regions:
| Report Type | Meaning |
|---|---|
| Executable Holes | Areas not covered by sections |
| Module Holes | Unclaimed space inside valid sections |
| Overlap Conflicts | Multiple modules claim the same region |
Color highlights make gaps (yellow) and overlaps (red) stand out immediately.
[TABS]
├── Sections → define + lock sections + set EXE bounds
├── Modules by Name → assign in-section ranges per module
├── Modules by Section → assign module owned ranges per section
└── Reports → holes and overlaps table view
All address inputs accept hex (0x, plain hex, or hex + H/h suffix).
Add/Edit dialogs support pasting 2 space/new line-separated values for start and end bounds of a range.
- Set Executable Range
- Define Sections (.text, .data, .rdata, virtual pools, custom regions)
- Add Modules & allocate ranges
- View Reports for:
- Global unmapped space
- Section gaps
- Multi-module overlap collisions
Refine until map becomes complete & conflict-free.
- Saves automatically to
project.json - Loaded on startup
- Persists sections, modules, ranges, locks, and EXE bounds
