Alternative: Softasm

cs_insn *insn; while (cs_disasm_iter(handle, code+offset, size-offset, &address, &insn)) // use insn->mnemonic, insn->op_str offset = insn->address + insn->size - address; cs_free(insn, 1);

If you have relied on SoftASM (SoftAnywhere’s x86 disassembler engine) for projects like binary instrumentation, unpacking, or custom disassembly, you may have noticed its limitations: outdated x86/x64 support, lack of active maintenance, and no ARM architecture coverage. Softasm Alternative

while (offset < size) disasm = asm_disassemble(handle, offset, code+offset, size-offset); // ... No ARM, no 64-bit on some branches

Here are the three most capable for modern reverse engineering and binary analysis. 1. Capstone Engine (Best Overall Replacement) Capstone is the industry standard today. It supports 8+ architectures (x86, ARM, MIPS, PowerPC, SPARC, etc.) and provides a clean, thread-safe API. Capstone’s cs_disasm_iter() works similarly

No ARM, no 64-bit on some branches. Strength: Very easy to integrate for x86 disassembly only. Quick Comparison Table | Feature | SoftASM | Capstone | Zydis | |-----------------------|--------------|--------------|--------------| | x86_64 support | Partial | Full | Full | | ARM/AArch64 | No | Yes | No | | AVX-512 | No | Yes | Yes | | Python binding | No | Yes | Via third-party | | Actively maintained | No (legacy) | Yes | Yes | Migration Tip SoftASM uses a stateful, iterator-based API. Capstone’s cs_disasm_iter() works similarly, so replacing the core loop takes ~1 hour.
