Wii Gets Custom Firmware, Purported PSP Emulator 68

Posted by ScuttleMonkey from the radically-different-definitions-of-working dept.
Engadget is reporting that some recent unofficial Wii modding news has had a couple of interesting breakthroughs. First, it seems that a team has released what is being called the "first custom firmware for the Wii" that supposedly allows writable DVDs to be read in emulators. Second, the folks from TeamShift have shots of a "working" PSP emulator for the Wii. Unfortunately "working" only means between 4 and 8 frames per second, so still a long way from playable.

      Probably not fake, but also probably not realistic, nor will it ever see widespread use. Knowing the PSP's specs, and knowing the Wii's specs, there is simply no way you can make an emulator run at a reasonable pace. The performance of the emulating machine must be *many times* faster than that of the emulated machine, to account for the massive amount of overhead. The performance gap between the two machines simply is not enough to make this happen.

        well.. the main thing behind PSP is that it has fairly fancy 3D chip inside, the CPU is not "that" good by itself. 3d acceleration of "slower" console emulation lowers emulation overhead very much.

        Not necessarily true. First of all the Wii is quite a bit faster than PSP. Second, they are both MIPS so you don't need to emulate most code, it can run natively. You just have to hook the right calls. Third, most PSP games do not access any hardware directly (all the rendering is done through a library similar to a very light opengl and all the file and audio calls are similarly through system libraries).

          That's true of nearly all modern consoles. Yet the last time I looked into GameCube emulators, they still showed very poor performance on a modern PC. And that's counting that most 3D emulation is done by using replacement libraries whenever possible.

            The 2x speed factor could be enough if the CPU emulation uses good dynamic recompilation.
            And efficient libraries replacement can give the necessary performance boost.

            That's how fast emulation of the N64 was possible back then.

            The main problem is that the emulator isn't mature yet :

            - Wii's target architecture is PowerPC. Coder haven't as much experience doing fast assembler optimization for PPC compared to IA32 (which 90% of the emulators currently target)
            - PSP's architecture is MIPS. This isn't an architecture that has been emulated as extensively as, say, the Z80 or 68k architecture (for those there are lots of ultra highly optimized emulation libraries).

            => Thus you won't currently get a high performance DynaRec egine.

            - The PSP is quite recent and the libraries replacement still have to mature a lot (compared to the current state of N64 or PSX libraries).

            => thus even if most game use mainly hi-level interfaces, the emulators aren't currently quite good at harnessing that.

  • I think that this has more meaning than just "oh, look, psp games!" I think that the fact that custom firmware is now running on the wii means that it will become the hacker's choice, if you will. It's already a huge success in the modding world, and this will just make things more interesting. I can't wait till they get a simple way to get scummvm running on the wii (yes, there IS a port for it). If they do that, I'll have a wii before the end of the month.

If I want to play MI I just select the homebrew channel from the wii menu, then select scummvm, and that's it. Piratey fun point'n'clicking from the couch.

    ... as usual.

    Let's set a few things straight:

    • Currently, there is no public method for reading DVD-Rs on an unmodded Wii.
    • This isn't the first "Custom Firmware" (I hate that word) for the Wii. Not even close. Not even the first public one. Or, alternately, this isn't and there has never been a true wii Custom Firmware, depending on how you look at it.
    • The "Custom Firmware" is only a small patch to the firmware that does two things: disable signature checks and disable a certain read restriction on the DVD code. What this does is let you use standard-format DVD-Rs (i.e. ISO9660 or Video DVDs) with the DVD drive on the Wii, but you still need a modchip.
    • The difference between this firmware and the original is exactly 5 bytes. 4 for the DVD maximum read restriction (an unsigned int), and one code byte patch for the signature disable. Hardly earth-shattering.

    We released a legal open source firmware patcher [hackmii.com] some time ago. Approximately three days before this purpoted "custom firmware" came out, svpe had added the DVD restriction removal patch to it (this was in response to an outright modification to an older firmware, released with the original code and hence illegally, by nitrotux, which he distributed with a disc dumper, but our patcher patches all of the recent versions of the firmware which use a completely different subroutine for the check, so the patch is different even though the result is the same). The first revision of Waninkoko's "custom firmware" was so hastily done that it was basically a PPF patch over the original firmware. Except it's encrypted. And he even changed the key. Hence, the patch was useless and he ended up distributing the entire patched-and-reencrypted file in the form of the patch (the entire patcher was 2MB, which is the size of the entire firmware). The fact that he made this trivial mistake makes me think that he did this very quickly and stole the patches from the open source patchmii (the DVD patch is identical except for the actual number involved in the restriction, and the signature check disable patch, which is relatively hard to find and there are several ways of doing it, is exactly the same). He later released a newer version without the blatant patch fuckup which is presumably legal to distribute now, although it still requires people to rip the original firmware from a recent game (whereas our open source patcher automatically downloads it from Nintendo's servers).

    Now onto the news. Recently, we actually did figure out a way of reading DVD-Rs without a modchip. Since this can be used for piracy (and could potentially cause quite an increase in it, since a free simple non-warranty-voiding pirate-game-playing hack is very appealing compared to the current modchip situation), we have tried to contact Nintendo about it (privately and publicly [hackmii.com]). If they ignore us, then we'll probably release an open source library and tools that will let Wii homebrew read information from a DVD-R on any Wii, modchip or not.

    For anyone trying to draw parallels between the PSP and the Wii, I suggest this article. As for the PSP emulator, I'll believe it when I see more than a single screenshot.

    • Recently, we actually did figure out a way of reading DVD-Rs without a modchip.

      Does this include DVD-ROM, DVD-R, and DVD+R discs? If so, then I'd guess Nintendo has no excuse not to make a "DVD-Video Channel" and sell it in WiiWare for 2000 points to cover the price of DVD format (MPEG-2, AC-3, CSS) licensing. That's what Microsoft did for the original Xbox: sell a copy of the DVD decoder software on a memory card and bundle it with a remote.

        That's correct. Technically, Nintendo could make a DVD-Video player channel. If Nintendo ignores our attempts to contact them, we'll give porting a DVD player a shot.

  • That is mostly on topic. There is a new Open Source wii emulator out that runs in both x86 and x64 windows. It was initially just a gamecube emulator, but it now emulates several wii titles, and shows perfect graphics until it realizes you have no wiimote, for which there is currently no software interface, either.

    But still, a wii emulator is ALREADY OUT that shows graphics, and it's OPEN SOURCE (now)!

      Would it likely be made to work with titles that can read GCN controllers, such as Brawl, Mario Kart, and (apparently) City Folk?

      • Eventually. It seems the pattern for emulation is: Nothing, then a few loading screens, then it's almost playable, then the games become playable, then the emulation steadily improves, and finally the gameplay experience is vastly superior to the original console.

  • I'd be happy if I can play my old MegaCD games on it, if only so I can do it without needing 4kg of power bricks.
