How can i fix these white dots on my touchscreen? (DS Fat)
I assume it's because the last owner played very rough with it, is it fixable? Or do i need to replace it
If so, where and how can i do that? How can i choose the right screen and model?

Context:
My ds is a fat model
I got this r4 yesterday and a 64gb kingston sd
I got this kernel off youtube because i tried to avoid the timebomb
The sd was exFat and i formatted it to Fat32
Now, important thing, i do not have PC, i'm doing everything with an app called Ultimate Usb
My problems are that all games are doing good except the Pokemon 5th generation games (black, white and sequels) stays all in white, never runs!
Also i tried install the Gbarunner emulator
First, i installed Gbarunner3 and it doesn't run at all, just shows the logo and nothing else
Then i tried Gbarunner2 and it worked, but doesn't run any game, i tried to put the bios file in every folder i could but nothing
Thank you for reading me
