I networked a 6502 a while ago in order to capture some behavior that isn&#x27;t well documented.You can interact with it using a wasm-based assembler in your browser. Programs only get 100 cycles to run but that should be plenty if you just want to poke around.<a href="https:&#x2F;&#x2F;chiplab.emulationonline.com&#x2F;6502&#x2F;" rel="nofollow">https:&#x2F;&#x2F;chiplab.emulationonline.com&#x2F;6502&#x2F;</a>

This was a fun thing to see after having just finished binging Ben Eaters 6502 breadboard computer series.Since it&#x27;s printing something out I suppose it also has everything else virtualised, would be cool to be able to provide it some machine code &#x2F; assembly

I’ve just updated the demo. Check it out here: <a href="https:&#x2F;&#x2F;carimbo.run&#x2F;play&#x2F;1.0.43&#x2F;willtobyte&#x2F;MOS6502&#x2F;1.0.6&#x2F;480p&#x2F;" rel="nofollow">https:&#x2F;&#x2F;carimbo.run&#x2F;play&#x2F;1.0.43&#x2F;willtobyte&#x2F;MOS6502&#x2F;1.0.6&#x2F;480...</a>

None of them run in a browser powered by WebAssembly. I created a 2D engine in C++20 based on SDL, in which I can use Lua to create games. Then I thought, “I’ll make a NES emulator,” so I started with its CPU, the 6502.

How many layers of virtualisation do we need?
