v4.0.0-beta1

The first public release since 2021.
REDasm has been completely rewritten with a brand new engine written in C and clean Qt6 GUI.

This is a BETA, expect rough edges, please report crashes, incorrect disassembly or any kind of bugs you encounter.

Highlights

• core total rewrite in C
• RDIL intermediate language for binary lifting
• save and load the analysis session
• the analysis database can be now exported for external tools inspection
• cross platform: redasm is now continuously tested on Windows and Linux
• renderer is now unicode aware
• GPG signed releases straight from CI pipeline

Loaders

• DOS COM
• all MZ family (MZ, NE, LE/LX with dedicated VxD device driver analysis)
• PE
• ELF
• Playstation 1 executables (PSX-EXE) and BIOS
• XBE (original XBox executables)

Processors

• x86 family (16/32/64-bit)
• MIPS32 (BE/LE) with delay slot handling and register tracking
• ARM, Thumb, AArch64

Analysis

• function noret propagation
• VB5/6 detection and structure analysis (eg. event handlers)
• autorenamer in finalization pass
• wide string detection (opt-in by loader plugin developers)

Known limitations for beta1

• macOS is not yet supported because I don't own that hardware and I cannot test it
• it's not possible to patch bytes or reassemble instructions
• .map exporter is not available
• currently stripped ELF binaries have limited test coverage
