Emulator of 486 in 2 days

After programming for 1+1/2 days and fixed compilation errors for the rest of the second day. I am done with the Emulator, it seems to work perfectly and I am happy with the result. There seems to be no execution error ~~at first time~~ except for sending registers to the interruption that was also fixed:

{"name":"zEDl.png","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/7\/9\/792282c0f1582f0175022e717e0632f2.png","w":492,"h":238,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/7\/9\/792282c0f1582f0175022e717e0632f2"}
{"name":"zEDU.png","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/c\/c\/cc49a122f124c0d42b92a719a0ab9c3b.png","w":669,"h":232,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/c\/c\/cc49a122f124c0d42b92a719a0ab9c3b"}

I show a portion of the most relevant code and the result of the execution.
What it does is first prepare the entire environment, so the text is at address 0x1000 and executes an Interrupt to print the text.

The emulator is completely an interpreter of bytecodes of X86 instructions in 32 bits, it does nothing more than execute instructions at the maximum speed of the machine. It stops the Interruptions, the Ports, and the zones of memories simulating a direct access to the Hardware.

I am still completing the hardware simulations and complementing my personal server.

The world can use as many emulators as it can get. Good luck RmBeer2.

And are you going to add sound like the drives running?

2. In the future will it be possible to emulate the sound of floppy drives (as for WinUAE) and the sound of HDD ?

Thanks best regards !

Leilei made a patch available here : viewtopic.php?f=4&t=3205 but it is not merged and I didn't test it.
