Windows 95 RTM error CPU: Undefined opcode 0x0F at 0x00000001

[Patrick64]

I've tried the "Save Machine" link on https://www.pcjs.org/software/pcx86/sys/windows/win95/4.00.950/ and followed the instructions (paste the code into a html file and add the js file) but then when I go to the html file it gives me the error "CPU: Undefined opcode 0x0F at 0x00000001". Anyone know how I can go about fixing this.
