Preview GC Backup Launcher for Wii

The last days I was working on a loader for GC backups. This is only a preview. The release will be within the next week.

A tester made a video showing it in action. Sorry for the bad quality.

EDIT:Here is a better video http://www.youtube.com/watch?v=4Xak8qdMKbU&fmt=18

Here are some notes:

I tested it with the games I have. All games seem to be fully working. There may be games which are not working.

IOS249 with backup support need to be installed (e.g. my cIOS r7 from backuplauncher 0.3 gamma).

DVD speed is still limited to 3x.

There are sometimes problems with the DVD read speed. So there is sometimes a very short delay in a few games. The game play is only barely influenced. This was only the case for one of my games.

If you eject the disc, no disc can be detected after it. For 2 disc games use the second disc to boot, if you need to change the disc.

You will need to copy the following files to a SD card, if you don't have a internet connection (either Version 5 or Version 6, both is working). There are problems with the nintendo servers in the last time. You may not be able to download it.

EDIT: MIOS Version 4 is also supported.

MIOS Version 5

EDIT: MIOS Version 6 seems not to be available from the nintendo servers. I thought that I have used it in the past.

MIOS Version 8

I know you can do AR with MIOSv4, but this thing requires V5/V6.[/quote]

How does Action Replay work on Gamecube? I've seen disc images for it online. If it requires you to load Action Replay disc, then change it out to the game, then I'm pretty sure it won't work since he already stated that changing of discs wont work (Have to load 2-Disc games from the 2nd disc).

I'm using a special wadder so I don't have to use the little icon ;) So once the dol comes out, I'll release this :)[/quote]

MIOS v6 seems not to be available. I thought that I used it, but the tmd file I used seems not to be version 6. So just download MIOS v8. You can also download MIOS v5 or MIOS v4. There is only one version required and it makes no difference, because the MIOS is not even really started. The GC Backup Launcher takes the full control very early.

Yeah, u do need an cube controller and memory card to play cube games on wii.

And yeah, a tester stated that it will be region free.


@wiigator
Your links to MIOS v8 are still linking to v6!?

great news on a great invention :O
just bought pc-parts to play gc and ps2 emulators on my machine >.<
i was just searching for a working gc emulator and on my daily round looking through gbatemp and wiisos i saw the post :D
great work wiigator and waninkoko !
hope you release the brew with a proper installation manual :O
so the dump guys lilke me can follow it :O

It's funny, a whole crowd from gbatemp said it was impossible to do, there were like yeh it'll happen in 1 year or never, mios is impossible to hack, threads were made "a road to gamecube back loader" and here he is Wiigator and waninokoko make a backup loader in a short fall of time behind our backs, they must've have been laughing.

@WiiGator: about the memory card data loss, I remember back in the cube day that you could not have NTSC-U and NTSC-J savegames together on the same memory card or it would corrupt the data or ask you to format it. As long as you don't mix USA and JAP games you should be fine. PAL+USA=OK, PAL+JAP=OK, USA+JAP=NO

I'll wait for the release to download the v8 MIOS files, since I'm getting a bit confused with all the versions lol!

Well if you would understand more, you would understand how complicated the stuff is, the 2 got to work. It not that easy as it was for wii backups, change change the Wii disc reading commands to dvd video reading commands inside the IOS. And as long as we don't get more technical details, we can only guess how it's done.

My guess(most likely wrong):
The loader reads the main.dol from the disc, patches the dvd reading commands there to dvd reading commands on IOS249, and then runs the gamecube game in Wii mode. If this was true, you could dream about ingame menus, real time saves, the classic controller as gamecube cotroller and sd card saves for gamecube games if you need something to dream about.

While I have really high doubts this is the case (since the MIOS is the one being modified here which is strictly gamecube mode code), if it was at all possible it would be real nice since we can finally get stuff like native SD save support and network adapter support.

But between of the fact that the MIOS is being modified here and that the extra hardware registers and even slight hardware differences are enough to confuse a GC game, it's gonna be run in GC mode most likely.

What if I don't want to save anything. Is it possible to play a game without a memory card? (with game cube controllers of course)

Yes it is possible, but it does not make any sense...

Great work Wanin and Wiigator!

I'm guessing that if the launcher does a lot of extra work (as opposed to the MIOS), then disk channel loading is unlikely eh.

Awesome to hear that GC homebrew is working too :)

Oh I know it's greedy, but any possibility to fit in cheat codes?

Good thing that my memory card from DX has a switch (so it's like 2 mem cards in 1!) That way i can have PAL+JAP on one half and USA on the other (assuming that you're correct). Woot!

WiiGator did say that MIOS is hardly used and that the loader takes control early in the process. We'll have to see later if that means it's actually running in Wii mode or not.
