I noticed the following while browsing the libnds video.h header:
Is is just me, or should at least the two first registers be defined volatile since the hardware can change the values between reads to the register due to fifo-action? I'd assume the GFX_CUTOFF_DEPTH register should be volatile as well, since you'd want writes to it to happen at the correct time as well.
