Hi! Pulled down w4 for Windows and did `.\w4.exe run .\cart.wasm` -- got a "cartridge is corrupted" message. It also said to check the console for details, but the PowerShell (or command prompt) console just has the QR code and the URL. Tried redownloading several times and also putting the cart file in different places in the filesystem.
I've heard of WireWorld and will be very interested to try this. Thanks!
