    Hello,

    I have been working on a project for quite some time now. Things have been going slowly, but I have been getting through it. I just have this one issue(right now). I am using Max Mod to stream a raw file. This is going great. I am also using OpenGL to render to both screens using textured quads.

    The issue I have is that when I run the game on my DS Lite with my Acekard 2i. I switch songs in MaxMod, and my bottom screen will flicker on the top screen and vice versa for the top screen. I have no idea why this is happening and I have been trying to fix it for 2 weeks. I can't debug it because it is on the console. I have a bitmap font rendering, but I'm not too sure where else to check.

    My streaming is just reading from a file. All the songs are in the same file. I just seek to where I need to be. I thought this was the issue. Maybe the file was taking too long to seek (it is a big file). I just seeked a portion at a time and when the file reached where it needed to be, the issue still occurred.

    I'm using the DevKit libnds examples to render 3D to the bottom screen. Is there a better way to do this?
    Any help would be amazing. Thank you.
