I will do x86 assembly language, nasm, mips, arm for 8086 on dosbox


About this gig
Professional x86 Assembly Programmer | NASM, MASM & DOSBox
Expert in low-level programming and Computer Organization and Assembly Language (COAL) for Intel 8086/8088. I deliver optimized, clean, and fully commented code using NASM and MASM within DOSBox.
Technical Expertise:
- ISA: Mastery of x86 registers (AX, BX, CX, DX) and flag registers.
- Memory: Expert handling of Data, Code, and Stack segments.
- Interrupts: DOS (INT 21h) for files and BIOS (INT 10h) for video/graphics.
- Logic: Advanced addressing, conditional jumps, loops, procedures, and macros.
- Data Structures: Register-level arrays, strings, and buffers.
Why Hire Me?
- Logic: Specialist in 16-bit real mode and 32-bit protected mode.
- Compatibility: Fully tested in DOSBox for legacy systems.
- Analysis: Expert in binary analysis, hex dumps, and .asm debugging.
- Clarity: Professional, line-by-line documentation for every project.
Services:
- Custom 8086/8088 projects and microprocessor algorithms.
- NASM/MASM optimization and C/C++ to Assembly conversion.
- Menu-driven apps and low-level system utilities.
Stop struggling with registers. Let an expert handle your Assembly tasks with precision.

FAQ
How do you ensure the code is bug-free for my environment?
I develop and compile every project directly in DOSBox using NASM. Before delivery, I perform a final run to verify that all register states, stack operations, and memory segments are behaving correctly, ensuring you get "plug-and-play" code.
Will I be able to understand the logic you’ve written?
Absolutely. Professionalism in Assembly requires clarity. I provide comprehensive line-by-line comments explaining every MOV, INT, and CMP instruction. This signals transparency and ensures you can easily explain or modify the logic later.
Can you handle complex hardware-level interrupts?
Yes. I specialize in INT 21h for DOS system calls and INT 10h for BIOS video services. Whether you need file handling, keyboard input, or direct video memory manipulation, I write optimized Interrupt Service Routines (ISRs) with precision.
How do you manage memory and segmentation?
Memory leaks and segment overlaps are common in 8086 projects. I manually manage CS (Code), DS (Data), and SS (Stack) segments to ensure your program is stable and follows strict x86 Real-Mode memory constraints.
What happens if the code doesn't run on my setup?
Your satisfaction is my priority. I provide a technical walkthrough or a screenshot of the output in my environment. If there is a configuration issue on your side, I will guide you through the NASM compilation commands in DOSBox to get it running perfectly.
