GoKawiilNew browser-based IDE lets developers code assembly for M68K, Z80, MIPS and RISC-V
A developer released a browser-hosted IDE that supports writing and running assembly programs for four architectures: M68K, MIPS, RISC-V and Z80. The tool includes a virtual screen and terminal, letting programs draw graphics, read mouse and keyboard input, or handle standard text input and output.
GoKawiil's interpretation of the reporting above, not reported fact.
Low-level assembly programming usually requires setting up cross-compilers, emulators and hardware-specific toolchains, which discourages beginners and hobbyists from experimenting. A zero-install browser IDE with built-in graphics and I/O support lowers that barrier, making it easier to teach retro computing concepts or prototype simple interactive games across multiple classic and modern instruction sets.
- Supports four architectures: M68K, MIPS, RISC-V and Z80
- Runs entirely in the browser with no local setup needed
- Includes graphics, mouse/keyboard, and terminal I/O for building simple games
Zilog Z80 Assembly Language Programming book — If a browser IDE has you itching to write Z80 code, a dedicated Z80 assembly programming book is the perfect companion for learning the instruction set and register tricks properly. It pairs nicely with experimenting on retro CPUs like the M68000 and Z80 right in your browser.
