That's illegal

When has that stopped anyone?

Does anyone know the maximum allocatable size we can get from heap ?
I have to allocate a buffer to copy an unsigned char array of about 990 000 rows . When I use MEMAllocFromHeapEx function it crashes, so i assume it's not possible to allocate a buffer that big...
If it's not possible, how can i allocate directly from the stack (and what is the stack adress range for the elf loader) ?.

I have another question, when i allocate memory for a struct, does it allocate memory for struct pointers placed inside the struct (as in linked list for ex) ?

Probably not unless you use u32 MEMGetBaseHeapHandle(int arena); void* MEMAllocFromExpHeapEx(u32 *handle, u32 size, int alignment); Be sure to check if the alloc value returned is NULL.
EDIT: whoops, changed something, need to pass in the arena, want to do MEMGetBaseHeapHandle(1);

Not to be off topic, but when do you or a supervisor plan to unlock iosu thread?

I can't do it A mod will probably have to or I'll start a new thread when IOSU is released, I guess?

Do you know if Hykem confirmed iosu to be released before march or any release date?

Nah, it was just a general time-frame. Nothing concrete.

Has he updated you on the progress lately?

So... anyone developing a NES emulator?

Not currently. Until IOSU is released, no emulators.

Should I turn off my wiiu internet to be on the safe side

Yes, or:

>You could use your router IRL filtering/Parental control to block updates
>Use the Tubehax DNS (forgot the adress, sorry)

I mean, I could learn how, but I'm better off documenting stuff for others like a certain someone else is doing ¯\_(ツ)_/¯

Could you please? That would be a huge announcement in the Wii u homebrew world.

...learn from scratch? That could take months/years until it's playable lol xD

Thanks but it doesn't work...
Must be something wrong with my code :

    uint32_t coreinit_handle;
    OSDynLoad_Acquire("coreinit.rpl", &coreinit_handle);
    uint32_t (*MEMGetBaseHeapHandle)(int mem_arena);
    OSDynLoad_FindExport(coreinit_handle, 0, "MEMGetBaseHeapHandle", &MEMGetBaseHeapHandle);
    uint32_t *memalign, *freemem;
    OSDynLoad_FindExport(coreinit_handle, 0, "MEMAllocFromExpHeapEx", &memalign); 
    OSDynLoad_FindExport(coreinit_handle, 0, "MEMFreeToDefaultHeap", &freemem); 
    void* (*MEMAllocFromExpHeapEx)(uint32_t heap, uint32_t size, int align) = (void*(*)(uint32_t,uint32_t,int))*memalign;
    void  (*MEMFreeToDefaultHeap)(void *ptr) = (void (*)(void*))*freemem;

    uint32_t heap = MEMGetBaseHeapHandle(1);
    void *buffer = MEMAllocFromExpHeapEx(heap, 0x200, 0x20);
    if(buffer == NULL) OSFatal("Memory allocation failed");
    OSFatal("Buffer allocated");
    MEMFreeToDefaultHeap(buffer);

It crashes before OSFatal... no clue

I think there would be more chance getting Retroarch ported to the WiiU. But I don't think Twinaphex has the hardware. Retroarch with the Lakka GUI would be awesome

Aww...

What are you trying to do?

I know I'm new, but your IF syntax looks wrong... if () {};

The loader works great. Thanks!

Keep in mind that it can never get to MEMFreeToDefaultHeap.
