wassup dudes!!! one question... I have a ps2 slim silver NTSC with a matrix infinity chip, and I used ULE to load the Hd_Gui, and the Memory card emulator and when it told me to change disc,I put the game disc and it said: wrong image file.Then I saw that it could be that ps2 didin't read the disc because the lid opened for the disc change,so I opened the play and covered the sensors with scotch tape so that the ps2 didint find out that the lid was opened in the disc change.
Then I used ULE to load the Hd_Gui, and the Memory card emulator and when it told me to change disc,I put the game disc and it said: Image file found and it worked perfectly but only with PAL games.
When i put a NTSC game, the Memory card emulator it reads the disc but it starts to load the sreen goes black.
I would like to know if there is a way to fix it????
