The 9w machine integrates the rectangular transformer into the main machine, but if the original 7w heat dissipation is built into the power supply, it will be bad, which will further affect the heat dissipation. This is just our subjective understanding.

However, when Sony released 9w, it stressed that it would optimize the cooling system of 9w, so you don't have to worry, just use it correctly.

Another difference is that the 9w base has returned to the early one, instead of the 7w round base, which is very beautiful (personally).

As for the games you can play, it depends on the reading rate of the direct reading chip you installed. There is generally no problem now. The cracking of ps2 is already mature. You're not playing the original, are you?
