I got a Matrix MX4 out of a old PS2. It whould like to use it in another PS2, but i don't what the specs of the chip are.
Is it a original Matrix MX4?
Can the firmware be upgraded?
If so, does the Matrix Infinity firmware work on it?
Does it support v13-v18 (scph 90004)?
I am asking all those questions here, because the Matrix site isn't very usefull (almost empty).
