First of all, PSP3000 is obviously different from 2000 in appearance. Look at the shape of the shell carefully. And the home button was changed to the trademark of psp at 3000. You can compare it. Even if the surface is not obvious, look at the software inside. If you download a software called motherboard information detection software on the video game bus, just buy it. My PSP 2000V3 (the last product in 2000) is 88-V3, which means it is ok to buy it around 90.
