i have what i believe to be a version 4 ps2. i think its a version 4 because it has 8 screws on the bottom and only 2 screw slots in the expansion bay. i got this ps2 from a guy that removed the sticker to put on his broken ps2 so he could return it. so with out the sticker i don't have the serial number or date code. this is why i am going by the 8 screws on the bottom.

i ordered a usb mod and installed the link wire. i used the version 4 diagrams. i put it back together and it won't load my back ups. it won't load my scratched gameshark v1.0 either. my v3 with neo2.2 does load the gameshark v1.0. i tested originals on this usb modded ps2 and they play fine. i tried both the top and bottom usb port as well. i even de-soldered and reconnected the link wire twice to make sure i had a good connection.
i tried doing the EA boot method and when i let go of reset the tray doesn't open. i have to press eject.


does anyone know what i am doing wrong? what should i look for?

did u intall it right man
recheck it and get a new gameshark

i got it to work. i'm using the game shark upgrade disc i got from interact.

but when i EA boot and hold reset the tray still doesn't eject when i release reset button.

usb mods dont work with ea method only neo2.2....i think

You are correct, there is no EA method with the USB mod. You need to put EA patches on EA games

oh. ok. thanks.
