It's normal for build tools to only produce object files, unless you use extra options to 8086 16-Bit Disassembler written in Assembly Disassembler for 16-Bit 8086 Intel CPU byte code while it itself was written in 16-Bit MASM/TASM assembler language. delorie. You’ll probably want to use the Cutter GUI The next major goal is to cleanly rewrite the disassembler module and transition from static code disassembly to execution flow tracing.
