Shameless plug: I cobbled together a simple VSCode extension for (so far) KC85, C64 and CPC - only for assembly coding/debugging though. The 'special sauce' is that the assembler and emulators compiled to WASM and directly integrated into the extension (e.g. the emulator is running in a VSCode tab, everything is properly sandboxed): https://marketplace.visualstudio.com/items?itemName=floooh.vscode-kcide https://marketplace.visualstudio.com/items?itemName=floooh.v... ...and it even works in the VSCode browser version, e.g. you can go here and press 'dot' to start into VSCode: https://github.com/floooh/kcide-sample-kc854 https://github.com/floooh/kcide-sample-kc854 It *is* really quite amazing how productive 8-bit assembly coding feels with modern tooling (e.g. when you have a tight edit-build-debug loop, and having a debugger that lets you inspect the state of the entire hardware, not just CPU registers).
