@robinduckett I really don't know? You could test this with some code. I focused on the 6502 chip because I was interested to see if you could program machine code with the code.
An integer benchmark perhaps?
The sound is broken on my machine and disabling it from the options somehow makes it sound even louder.
Did you find a solution to this? I had no problems with sound the first time I tried it, but since then I'm getting what you described.
We used this emulator as a reference source frequently while we were developing DiscoRunner. It's pretty good for JavaScript =)
what! No Burger Time! Bah!
or Beer Run for that matter
warning on the sound levels. Turn down the mixer controls before clicking.
