Emulating Hardware is it possible

[3Dimentinal]

So I am wondering if you could make a program think you have certain hardware almost like an emulator.

[Jurrunio]

You could use regedit to fool the more basic programs, but those meant to read correctly like CPU-Z can't be tricked without modifying the BIOS.

I think some virtual machines can do it.

I am hoping so this it the path I was hoping to take. Would you know where to start my Journey?

I am looking to start my build with Linux wold you have a recomdation for what one I should go with if wanting to modifying the BOIS

why would you want to fake the hardware in the first place?

something like fake gpu by flashing bios to a different card?

what next?

I am looking to run an os but it does a hardware scan and will not let me run it. But I am looking to do it on a virtual desktop for testing

No more like running a fake BIOS saying it certain Hardware so special ok can run on it

which OS, out of so many Linux variants?

I am looking to run the original Xbox os but I'm being hardware blocked.

What Linux os would be best to run almost like a virtual machine.that I can preform a hardware fake.

then forget it. I've seen faking CPUs to different models that's in the same socket and architecture with the BIOS, not a completely different CPU architecture.

 

How expensive is an Xbox anyways

There's more to it than just showing up as different hardware, the original xbox didn't have an x86 cpu so you straight up can't run it on a normal pc without a full emulator. The vast majorty of good games for the original xbox are available for pc anyway so what's the point?

[3Dimentinal]

There really isn't a really great point I am just looking for a cool project to take up my time.

All right well thanks for letting me know but with me being me and all ima still try it may be a lost cause but I might have fun screwing around.

The Xbox used a Pentium III, so it was X86. The issue with this is that you won't be able to do anything with the OS even if you did get it to boot. There are just so many things that will prevent you from doing this at all.

Shoot even if I got it to boot I wouldn't be able to use it?

Not really. What do you expect to be able to do with it?

Just run old Xbox disks

Yeah, that's not really going to work. You're much better off just getting an old Xbox. You can get one for around $10-15 USD used in working condition.

Ahh man I was hoping to have a project to work on

yes, software pretending to be a hardware is called emulator. If you are interested in creating one, this is the highest view of what it may look like. 

char* memory = malloc(40000000000); // reserve a memory of 4GB for our virtual machine 

void run(instruction next_instruction){
 while(1){
  switch(next_instruction){
    case add: rd = rs + rt; // add registers 
      break;
    case subtract: rd = rs + complement[rt] // subtract
      break;
    case jump: ........ // jumping to another instruction and so on. 
  }
 }
}

Of course in reality it is much more complicated but that is the general idea pretty much.

about the closet i think you can get to what you want is to try looking up these

 

xbox specs

and using source / template design form one of these

Qemu and Qemu wikki

 

bochs and bochs wikki

 

to build  a new bios/ computer hardware set  (as wasab said) with appropiate mapping.

 

ie hdmi to your graphics card / screen, xbox controller to keyboard/ mouse etc.

 

however if there is any DRM or security features that are looking for specific Identification of the xbox it will still probably fail.
