Show HN: A browser IDE for m68000, Z80 assembly (and more), with graphics

Asm Editor is an open-source browser IDE for writing, running, and debugging assembly. It currently supports M68K, Z80, MIPS, RISC-V (32- and 64-bit), and x86-64. The debugger includes breakpoints, backward stepping, execution history, register and memory inspection, and other tools intended to make assembly easier to understand. I recently added graphics, keyboard, and mouse support, so it’s now possible to build small games and other interactive programs. The project is aimed primarily at university students learning assembly. The M68K emulator takes inspiration from Easy68K, while the MIPS emulator uses the same emulator as MARS. Both are commonly used in computer science courses. I’m also working on interactive courses for those architectures, allowing students to learn and experiment directly in the app. The app also has architecture

documentation, shareable files, project templates, and tools for professors to create exams. You can create a project from one of the templates to quickly try it out. I’d love to hear your feedback, particularly from people who teach or have learned assembly.

I made a web IDE to teach assembly languages. My goal is to have a single webapp where there are courses, documentation and IDE of all assembly languages. It's full of features to make it easier for beginners to understand how things work: - instruction undo and step - breakpoints - function stack tracing and stack frame view. - history viewer (shows the side effects of each instruction) - I/O and memory viewer (both number and text) - number conversions for registers and memory - testcases (useful for professors making exercises) - auto completion and inline errors, etc... It also has an embedding tool to be able to embed the ide in other websites. And be able to share a project by URL. This way professors can create their own courses and exercises to share with their students. Repo: https://github.com/Specy/asm-editor Next i want to

improve the x86 emulator, add ARM, Z80 and chip-8. I'm also writing assembly courses, if anyone wants to help out writing them, the repo is open to contributions!
