Learn Wii assembly, develop a GB emulator.
That's what I'd love to see.
Wouldn't it be technically PowerPC assembly?

And heh, I think there will be GB games offically. They probably plant to do some kind of Wii/DS connectivity involving it too. Hell you can probably make it so you play the GB game on the DS, but save progress on the Wii.

That would actually be pretty awesome. Hurf, someday there might even be Windows 95 on the Wii

But that would require a whole IBM PC emulator. xD I don't see the need for a virtual PC on a Wii...

I guess a lot of stuff will be cleared out whenever Wiinux comes out.

Well of course, open source operating systems are usually the first to get ported to a device. And there's no need for virtual machine, you only need to port it..

ENCRYPTION! ENCRYPTION! ENCRYPTION!


How are you all going to deal with the fact that Wii game discs and Shop Channel-downloaded software is freaking encrypted? (See my previous post for details)

ROMs are bundled into the emulators, to speed things up and defeat any potential piracy. It seems easier to do it that way then fuss with emulators in firmware.

You can't run Windows on a Wii because the Wii uses a PowerPC processor, not an IBM x86 processor. Won't stop things like Linux, BSD, and even a potential for OSX, however. But you still have to deal with ENCRYPTION

It could possibly be bypassed with some sort of Wii modchip.

You can't really "bypass" encryption. Modchip or not, you'd still have to decrypt it. The most likely thing to happen is that there will be a modchip that loads an emulator for generic roms, completely seperate from VC games. But since we're not talking about your usual run-of-the-mill ROM here, we'll leave that for another day. Since the DS games were RSA Encrypted, and they're being emulated now, I forsee that it might be moderately easy to figure this out. Not only that, it's based on souped-up GameCube hardware for which homebrew already exists. It probably won't be hard to get something working fairly easily. IIRC, homebrew for Wii is already possible through Modchips.

The NG code in the games is a console identifier for which game came from which console. If you own the game, the NG code doesn't matter.

I figured that out months ago..

The Wii archives the VC games and puts it on SD card. The game is then extracted with the help of a file checklist which is permanently stored on the Wii's memory to the directory, Root-CA00000001-MS00000002. If the game's directory and file table isn't in there, the games wont copy across.. Those files are only created through the TMD files when downloading the game, but you also need Nintendo's key to install them in the first place.

On top of all of that, the NG code has a checksum, which, if it isn't correct, the Wii will reject flat out.

The only way to circumvent all of this is to set up a private server and send the TMD files through the shop to your Wii, but Nintendo locked that exploit out. Hacking VC games isn't possible, and you are in NO way any closer because you discovered your console has an NG code.

That doesn't defeat the checksum, and that doesn't defeat the Wii's file list.

Apparently you do not understand how RSA encryption works. Let's put it this way. You have two large 100 digit prime numbers. Multiply them together and save that result as C. The two prime numbers that are its factors are A and B. You are given C but to unlock the encryption you have to find either A or B. A and B are referred to as "keys." If you know one you will know the other. Think about how many prime numbers are in the range of 1 digit numbers to 100 digit numbers. Those numbers are huge! This does not imply that the numbers have to fill out 100 digits, but generally speaking they are made sufficiently large that trying to find them is extremely inefficient, and thus difficult. So inefficient that it would take several lifetimes to go through all the possibilities, if not the end of the universe.

Quantum computers could do it in hours though.

I'm pretty sure a mod chip could clear this up but now that nintendo is updating the firmware, they might find out and lock up any easy way to mke the chip.

1) DS games aren't encrypted with RSA. DS download demos are. The only method available to beat this is replacement firmware that took some time to make, and all that does is allow unsigned code to run. The Wii has downloadable firmware upgrades, which will break this.
2) Mod chips cannot defeat firmware downloads - especially forced firmware downloads. The exploit Nintendo locked out was the one that allows people to use the Shop Channel as a web browser.
3) RSA is used because it's currently uncrackable. You need a quantum computer in order to brute force a key.

I'm sorry to burst your bubble, people, but Wii homebrew is a looong ways away right now.

Exactly my point.
I honestly don't mind if we're not getting a Wii homebrew in 2007, but someday though, I'm sure.

Sony used RSA encryption on the PSP, and it was still completely and utterly hacked wide open for homebrew.

Right now, there may well be some form of exploit in the Wii's firmware that just hasnt been found yet. If such an exploit is found, then the chances of successful homebrew increase by quite a bit.

Worst case we just have to wait for quantum computing becoming a thing that the commmon man have, and can afford.

I guess they have a some kind of a compression or something.
I remember trying to open Classic NES: SMB in Tile Molester. Got nothing.
I almost want to say the reason for this is because those games use almost a filesystem of sorts. If I recall correctly, the ROM contained both the NES rom, and PocketNES with modifyed sound code (...way to go Nintendo?) within it. I think to edit the NES rom within it you would need to somehow de-attach the file. Of course, on the subject of the VC games I HIGHLY doubt that they would be bundling the emulator with the game, but considering that they more than likely don't have them built in, I can't see any other way. Perhaps its done similarly to how these GBA games were done. Dunno.


Nintendo did not use PocketNES for their Classic NES series games, but other companies did. Atlus, Hudson Soft, and Jaleco have sold PocketNES attached to their roms.

Last view: 6114 days 		I don't know much about how this all works. Does anyone know if there's a chip inside the Wii that runs all the VC games, or is it a game built into a Nintendo made emulator? Either way I could foresee a program that would allow your average ROM to be playable with the built in Wii hardware through a homemade program. Or if the VC systems aren't built into a chip in the Wii, once you could seperate any game from it's possible emulator (or even use a homebrew emu), you could have a program that would take any ROM, and form a "new" VC title with no encryption. But then again, I don't know how any of this works, so this is all strictly theoretical.
