GPU shaders for bleeding edge?

I heard from someone that the gpu shaders were pushed for bleeding edge. And their screenshots in a certain site showed that indeed it fixed fire emblem echoes and a few other games.I tried the latest Bleeding Edge and played echoes but the problem of black lines still exists.

GPU shaders, or geometry shaders?

You’ll have to hack-patch the ROM to remove black lines. Google it up for details.
You can also use cheats to remove them. See
