About Mnemonimov
Mnemonimov (pronounced nee-mo-ni-move) is a low-level programming sandbox inspired by early game consoles. In this fantasy console, you program in assembly language with full control over execution, rendering your games and other creations to a retro monochrome screen.Start by building simple games or exploring the included sample projects, then expand into more complex systems as you build everything from scratch. With no tutorials or challenges, you work things out by experimenting. Read the manual, write code, run it, debug it, and repeat as you go.
- Expressive assembly language with RISC-style memory access, floating-point operations, and vector instructions.
- 32-bit register-based virtual machine with a rich instruction set.
- Labels, constants, bookmarks, and related directives for structuring large programs.
- Support for referencing external assets, including images and binary files.
- Integrated code editor with syntax highlighting and detailed error reporting.
- Debugger with step-by-step execution, breakpoints, and inspection of registers and memory.
- Command-line interface for managing projects and configuration.
- Retro monochrome screen with 320x240 resolution at 60 Hz.
- System calls for user input, rendering, terminal output, and system interaction.
- Persistent memory storage for saving program data across runs.
- Integrated technical reference covering the architecture, assembly language, and ABI conventions.
- Large memory limits with no restrictions on code length or execution speed.

really cool and works on linux4 found this helpful
I'm a complete novice when it comes to programing and have never touched Assembly in my life. But after tinkering around for a little bit, I had found myself spending the entire day programming in this making cute little games. The in-game documentation is easy enough to understand and provides pretty much all the information you need to get started. The sample projects that comes included is also a big help to study and reference for your projects. Overall it's fun if you have interests in programming or challanging your ability to understand and problem solve via projects and hobbies.2 found this helpful
Mnemonimov is ok but if you're going to build your product around the concept of learning and using an assembler and debugger, provide at least the common functions of a window giving the user a view of registers as well as a way to browse memory. There's no good way to see what's going on in memory and it would be immensely helpful to new assembly programmers to be able to watch the registers as their program runs. Mousing over register names in the code to see their value isn't really good enough. Also, the documentation is only provided through an in-game help facility. Docs provided in the form of a pdf file would be awesome. All this said, I'll tip the scales in favor of a thumbs up because the tool does technically work. It is however missing some basic functionality. That said, it can be fun if you're the type of person who enjoys programming.1 found this helpful
close the game when i hit close. im not typing the letter. dont make me use the steam reaper process i just wanna close the thing when i wanna close it. Other than that, its good. buy it.
It's crazy to me that this exists. For context, I'm studying towards being able to analyze malware; this requires a large set of skills related to understanding how hardware and operating system work and communicate. One of those important parts? Assembly. It may not be 1-to-1 ARM64 or x64, but it serves as a fun way to interface with what is considered a very niche skillset (being able to understand and work with assembly).
I'm very much into programming and electronics and had been wanting to dive deeper into assembly after learning some 6502 on the C64 so this was right up my alley. In addition to assembly I've been making toy projects in Pico-8 for years and always hoped someone would build something like a fantasy console for assembly.. and you did! And you did it GOOD! It's very well designed and I must say I like the MISA assembly language a lot. I think Mnemonimov is an excellent learning tool and it has a huge of amount of potential. It's already very usable but I'm excited about its future. Personally, I'm looking forward to being able to generate audio (hoping that's coming in a future update) so maybe I could make a little sequencer or a synth and also being able to interact with other people's creations. Very nice job on MISA, the manual and the IDE. I'm going to be having fun with Mnemonimov for years to come. I give it a solid 12/10.
