Seems to be VICE running in a web client? VICE is a well-known Commodore 64 emulator that's been around for 28 years. I'm not sure why I wouldn't just run this locally? Serious question - what is the advantage of this?

Running it on Replit I had to answer a multi-stage CAPTCHA identifying all trucks and then it was so slow I couldn't even type without holding the keys down for several seconds before they would register.
