I got the EZ FLASH DE like a week ago and I loaded this cool menu but the problem is that the pictures don’t match the rom hacks. I tried doing a tutorial I saw, it fixed the images but then the games wouldn’t load. Soon as I booted them the screen turned white so I deleted them and re-added the original rom hacks, how can I fix this?

Could someone explain to me why my GBA Does this?
When turning on, I don’t hear the whole jingle but when I cut it off right away and turn it back on it does a weird sound.

Can someone explain to me how to hide folders on the DS PICO???? I tried naming the folders with periods but it doesn’t let me. And I have no idea what or where the Hidden Attribute is
