2. Go to other websites and try different versions of the game. When the version is changed to CSO or localization, some games may conflict with the system.

Go to the video game bus, and then take the next 5.50GEN-D3. I use V3, so I don't know your system, but on the same day that 5.03GEN-C and 5.50GEN-D3 were released, it seems that many situations like yours appeared. In the past, the game was black, and some people complained that CSO couldn't stand it. 5.03GEN-D3 had a BUG at first, but it was reissued, saying that the BUG had been removed. Please try it.

Then try the last method. You can find someone else's memory chip and install your PSP to try those two games. If there is anything wrong, it can only be that there is something wrong with your machine or the game. If there is no problem, there is something wrong with your memory stick. I'm inclined that you may have a bad contact with the memory stick. If you can't find anyone, try to find a clerk at the place where you used to buy PSP.
