We can allocate memory(OSAllocFromSystem,MEMFreeToDefaultHeap,MEMAllocFromDefaultHeapEx,MEMAllocFromDefaultHeap)(MEM 1 has enough memory)(There's a mem map http://wiiubrew.org/wiki/Cafe_OS).
32 Kbytes without elf loader.

32 Kbytes without elf loader.
We have good enough games so far. Unless that quote was before everything was revealed.
I actually agree with him, wiiu has been a major disappointment and nintendo should be ashamed of themselves how they handled it and how they have treated the wiiu users.
Loll please..dont make me laugh!
you see, thats the difference between someone who thinks "well, better then nothing" and someone who thinks "they actually could have made better!"
They make game ripoffs and they lack features on their console..i always loved ninti, but its a fact that the wiiU is disapointing.. oh but yah sure, some games are worth playing..just not worth paying 74$
What would an ELF loader change?
From my understanding, an ELF loader is copying code/data sections to memory then jump to code entry point for executing a program.
If you are limited to access 32K of memory, how would you load anything bigger?
And where can you load the ELF from? SD? USB? Are they even accessible in current User Mode state?
About the Wii U hacking thing, I'd love to give it a whirl. Doing simple stuff like finding unused artifacts, changing a bit of code, and messing around in general is fun as hell for me. But I'm pretty sure I have no chance of getting it before release, even if I can proof that you people can trust me.
You can test me if you want.

Not to mention the 32MiB JIT for storing code and rodata sections.
So, let's suppose that an elf loader appears and that memory restrictions is not more a restrain, what would be a good starting point to work on ?
i mean, which language and toolkit should be used ? and how much effort would it take to convert things like emulators and other things on the wii U ?
We need a toolchain for compilation i guess, what is currently availble.
Except from Unity3D and scratch, i've never dev, but i'd love to make some simple trials with a bit of example and sources to learn (yes, i've yet crawled a bit the lib on WiiU but i did not find so many additional resources to handle GFX, sounds etc.

Ok, so the 32KB limit is only the max size of executable being loadable trough the web browser (maybe with static / BSS sections included) but executable loaded via the current exploit could in theory dynamically allocate up to 32MB (or quite) in MEM1 for its own use?
ROP can call symbols and load different API methods so you can copy data over whatever memory is available (not protected by MMU?), then jump there I suppose (user->kernel mode)
the problem I ran into is that yes, they are 32MB for code alone usable, but there is nearly no memory for writable data on 5.3.2, its like maybe 1MB. On my 3.1.0 though I can easly use like over 300MB for writable data without any crashings or issues.
There's 1GB memory for games and 1GB for system software.
What needs to be done to get access to the "game RAM"?

If they wanted random people on the internet to have the exploit they'd have released it already, you're just making yourself look stupid by constantly asking and acting like you have no idea what you're doing.
Hahaha. Good one.

Not sure why people reply in a dickish manner here.
may be they are fed up with brainless enquiries like "give me your work because i'm a good boy that you don't know, and i promise i will keep it for me"
I've been making great progress on a lot of neat things, my exception handler can now be used to create ghetto breakpoints. It still lacks some features, but I am aiming to overhaul thecodehandler that handles all the WiiU<->PC connectivity in the next few days.

yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done -

TwoSpikedHands:
I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer

@
TwoSpikedHands:
Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?

Sicklyboy:
@TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one -
@
Sicklyboy:
I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version

TwoSpikedHands:
@Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!

@
TwoSpikedHands:
I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
-
@
TwoSpikedHands:
I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
