Programming a Console Questions

I am a little curious. Is it possible to use the hardware of another system to turn it into another console?
Idea such as... Taking a PSP and actaully turning it into an emulator. Not using an emulator, but actually hard coding an emulator so that it only knows how to play Roms of that new console.

Example:
Taking out the PSP software and install dreamcast software to emulate Dreamcast only.

Just a thought, I probably don't have the full skills to do this, but i am interested if it is possible.

FAQ:
(so i don't have to answer questions in my own question)
Why would you want to do that to a PSP?
I have three of them, so it wouldn't matter if i did it to one.

 

If I understand what you are saying correctly you want to install essential a new OS/Firmware on one of your PSPs so that when it boots up and turns on and acts like a Dreamcast right?

If that is what you want I don't think that is possible. Sure you can hack the PSP and install a ton of emulators on it, but you can't make it into another console . . .

yeah that was i was asking. But what if you programmed new FW for read Dreamcast like they did with the PS1 emulator?

 

The PS1 was different because the hardware inside the PSP is literally a miniature Playstation, so they didn't really have to write an emulator for it because it used the hardware inside the PSP to run.

All kinds of wrong in here.

No, the PSX emulator in PSP is just software. The PS2 has hardware backwards compatibility with the original PS.

The answer to this is no, and from everything else you've written you're getting very confused about the distinctions here. Firmware isn't hardware, it's just low-level software. There is no way to turn the PSP hardware into a Dreamcast, regardless of what you do at the firmware level.

 

Really I thought it was hardware as well, thats news to me, sorry about getting that wrong.
