I wouldn't be surprised if it has to do with the fact that it is used inside an R4 (because ds games are expansive) and thus might have something that could have been seen as bootable.80 Yeah... you should get that looked at.
Considering it has programs on it that should crack the SD to get its own stuff running instead of whatever the ds wants to boot......82 That makes sense.
"Why won't the computer boot?"
"Because you stuck your game into the boot disk slot."
