Stop complaining about your damn DS and GBA shiat.
Wanna use it, do it from sysnand.
Besides, booting DS from sysnand doesn't unstick the mset exploit and when you leave the game you can use DS right away (on emunand, leaving a DS game boots you back to sysnand).
Think about it
Or instead of flaming us for bringing up a legitimate bug, you could've just let us figure out why it happens and then fix it. We're not even talking about sysNAND or MSET, so I think you're looking to start an argument just for the heck of it. Please take your attitude elsewhere.
