There are apparently 2 slot-2 motion peripherals, one is a third-party "motion pak", the other is the "motion pack" used with a Tony Hawk game. Are they functionally the same? If I were to buy a motion pa c k (since I can't find any motion pa k s online) would I be able to use it with libnds?

I've made yet another workaround where the arm9 detects sleep mode and turns off sound emulation until sleep mode is done... so I guess this isn't an issue anymore. Hopefully it won't come back to haunt me.

My workaround was unsatisfactory, as it turns out. Putting it into sleep mode seems to sometimes cause the arm7 to crash, perhaps the arm9 was awake and sent too many commands while the arm7 was going into / exiting sleep? Making arm9 wait for a response again seems to fix this particular issue, but ...

The sound code isn't run from an interrupt handler, it's executed when the emulated cpu writes to the corresponding registers. It all descends directly from "int main()".
I didn't know about any exception handlers. I added "defaultExceptionHander()" to the initialization routine, but there was no ...

I picked up an emulation project for the ds which I hadn't looked at in awhile. For sound emulation I needed low-level sound access. Libnds's "sound.h" functions worked fine... except when it crashed randomly. And I mean randomly ... I couldn't see any pattern to it. It could happen seconds after ...

Ah, so it was irqInit()! I must've been reading an obsolete resource. It works fine now. Thanks!

There isn't much I haven't said.

int main(void)
{
irqInit();
irqEnable(IRQ_VBLANK);

consoleDemoInit();
consoleDebugInit(DebugDevice_CONSOLE);

soundEnable();
while (true)
{
soundPlayPSG(DutyCycle_50, 500, 100, 64);
// Crashes here
printf("This command is never executed.\n ...

Hi, I'm attempting to port a gameboy emulator to the ds. I'm unable to play any kind of sound with libnds's sound.h. I call soundEnable() at the beginning of my code, presumably this powers on the sound hardware? As I attempt to call a function such as soundPlayPSG and soundPlayNoise, the ds crashes ...

I was afraid of that. Well thanks for the help.

Oops. Well now it works, almost.
I've uploaded a save file into Final Fantasy V, but I can't yet write data to Pokemon Sapphire. As far as I can tell it uses a 1Mb flash chip. According to the nocash technical info on the gba I'm supposed to use commands instead of writing directly but none have any ...
