What happened?

When I try to run Built-in Computer chip (Chapter 5) on hardware simulator , the test script stuck on "Loads the binary program Add.hack into the computer's instruction memory" and can't continue.

I tried Chrome Version 131.0.6778.70 and Edge Version 131.0.2903.51 and the both failed. What did I miss?

I just literally ran into this exact issue. Looking into dev console in Chrome reveals:

Stepping through the code with the debugger, I can further see that:

Error: File Not Found /samples/Add.hack at https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:245943 at new Promise (<anonymous>) at h.readFile (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:245888) at p.readFile (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:244961) at https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:399522 at i (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:399535) at u.load (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:356246) at w.load (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:381232) at o.loadROM (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:414576) at m.do (https://nand2tetris.github.io/web-ide/static/js/main.15cf674c.js:2:418105)

Okay, debugging even further, I noticed that my local storage did not have the .hack files. I made a backup of my HDL's, cleared the storage and refreshed the page – files are now there and the emulator works as expected.

Scratch that, it doesn't actually work.

Okay, made it work by using a local override for:

web-ide/simulator/src/test/instruction.ts

Line 222 in 634686e

test.fs.pushd("/samples");

and changing the directory to test.fs.pushd("05");, hopefully this would help to track the issue down.
