Portable from a smarthphone?!

[berinho]

I have a smarthphone with broken touch, then it is stopped, since it does not intend to fix it. So I thought: "Is it possible to turn it into a video game ​​portable? "
Can reuse a lot of stuff, like LCD, battery, and hardware. What do you think?

NOTE: As I said before, the touch is broken, the intent is to use buttons of a control.
Sorry my bad english.

to start with you need to find out whether you can replace the screen, failing that does the phone have HDMI compatibility?

The smartphone screen is intact, the only problem is that the touch is not working properly and it costs a bit expensive to replace. I think it does not have HDMI input, this really necessary?

If its a non standard touch interface your chances of repairing it are very limited.
