Yifan's Github said:
"Make all code run on thread 0."
"Close other spider threads: Right now, the main problem is that some other thread running on another core is crashing when the 0x00100000 code pages are replaced. We need to find what thread is running and using where the thread stacks are located, we patch the stack to return to CloseThread. This may be made possible by hooking ARM11 kernel undefined instruction vector and finding the SP of crashing threads."

I figured I'd create a thread in hope that the various developers that trek the forums would see and not know of his project. Yifan set out to bring The Homebrew Launcher to the browser for those that do not own copies of Cubic Ninja. He completed most of the issues, but abandoned the project quite some time ago. If I remember correct, he said it was because he saw a lack of desire for it in the community. I looked at what was needed, and it is far beyond my understanding. For those of you that may understand, and would like to help the community a ton, you can find the repository here.

It can be accomplished through teamwork!

It's not happening, m8. It hasn't happened for months and it's been brought up often enough for the relevant people to know.

Gotta support that defunct Cubic Ninja studio!

EDIT: New idea, though: Why not abuse the bootstrap stuff? Someone made it spider-usable in https://gbatemp.net/threads/how-to-spoof-firmware-to-access-eshop-and-more-on-new-3ds.386591/. That way, you could just launch a new KProcess, kill spider from within kernel and declare the new process the running process. There'll be a slight problem that the hb pseudo-service isn't running, but I have my doubts that most apps really need it in the first place.

I'm only gathered smea, Yifan lu and GW launcher data and know nothing note than is available to public :( Even Korean/Chinese/Taiwan versions of spider3DSTools fork is suspended because of no use without addresses of gadgets like file write, which I just can't get.

First, allow me to thank you for your work with fwspoof.

In my experience, you can't apparently safely write to anything in usermode from within kernelmode without a fixed address (which obviously changes because of memory mapping). Plus kernel mode from spider seems to be very picky sometimes and nobody knows why.

You can get those, actually. Get the NCCH and cetk for those regions from the CDN, get the decrypted titlekey (via Decrypt9), decrypt the NCCH with the titlekey (AES-CBC, dunno what the AES key is, though; I think it's related to something in the TMD). Load up the exefs for both in a hex editor, jump to IFile_* in a spider version you do have the correct offsets to, take eight bytes, and look for those eight bytes in the exefs for the region you don't know the IFile_* function address to. Prerequisite: Having an idea how the exefs address relates to the address in RAM, but that's likely just a static offset.

Cubic ninja carts have long since been out of production, and most (all?) retailers simply buy the product outright as far as video games are concerned, and eat the cost at the store level if it doesn't sell. I know this is a little off topic, but figured it'd be worth mentioning. Source - I worked retail for 12 years.

Especially since Pasta is out, finishing SpiderNinja would be amazing and groundbreaking, I bought Cubic Ninja but I know a lot of guys with not as much money as I have who'd appreciate such a thing to be available :)
