Hacking Making a backup solution for the wii

ivoback · Jun 23, 2008

Hello.
I am looking for peaple that can code for the wii.
We can work together to make an ISO loader.
I have some idea,s:

1. Boot a original game then swap it with a backupped one.
2. Watch the boot codes of a game and make a program that can do the same.
3. An external usb hdd where you can copy the games on.
4. Stream the games from network to the wii like the gamecube.

If al the peaple that can code can work together we can make it!
I cant code but i want to help and test i have a modded argon wii and zelda tp.
if you have any ideas for a backup solution post it here.

sorry for bad enlish im dutch

Oh my god that's the best idea ever.
Do you have time to tell it to me again?

A homebrew ISO loader wouldn't be impossible, but no body wants to do it because it supports piracy.
About network streaming: I know there's a FTP set up for the Wii already, but it sends the files to the SD card. Because most Wii ISOs are ~3gbs scrubbed and 4-5gb sd cards are pretty expensive, there should be an easier way around it. I have no experience with Wii Homebrew, other than using it, so I can't help you. Sorry.

Yeah, if you have a modchip, it would be easier to burn a disk or "make a homebrew"

I'm intrigued by your ideas and would like to subscribe to your newsletter.

what are the functions of a modchip?
maybe we can use a firmewire of a modchip and port it onto the wii or something strange

bennydigital · Jun 23, 2008

right after we port PS3 into the wii.

You're a non-stop ideas machine!

Slow down a bit, we need time to think about what you've already suggested.

lol i cant tell whos sarcastic and who isnt, i cant see an iso loader for quite some time on the wii,shame really.

But Ivoback's got ideas!

If only he had a vague idea what he was talking about we'd be half way there!

NEXT.

So let me get this straight, the OP basically wants everyone else to do the grunt work and when it's done he'll "test" it. Yeah that sounds fair, after all he has those groundbreaking ideas. Well I have an idea too, but it involves cramming something up where the sun don't shine.

That was included in something strange.
Sounds like you two are in perfect agreement.

USB loading is USB v1.0 which doesnt have enough data throughput for ISO streaming from the HDD

Im sure a Hombrew channel will be released to load backups, no doubt about that. ISO loading seems useless when you can sign a disc on the fly. Only a matter of time... (personally hope it doesnt)

Added some code. Not ready for iso loading but it will help us all out.

#include "screen.h"

u32 tvmode;
GXRModeObj *vmode;

int screen_w, screen_h;

long pg_showframe;
long pg_drawframe;

void pgBitBltSgb(unsigned long x,unsigned long y,u16 *d)
{
u32 *v0, *v1;
u16 color;
int r, g, b, cy, cb, cr;
unsigned long yy;
unsigned long xx;

x/=2;

for (yy=0; yy 10) & 0x1F)

network streaming is completely ass. it didn't work well for GC, it won't work well for wii.

More garbage on gbatemp from people who have no clue what they are talking about. Once again the thread is free to grow with more useless and false info. Just more fuel for the lamers and noobs that have no clue.

I don't think you'll need the extra speed of the dvd versus wifi-lan/sd/usb. Memory of the wii is already limited (24 + 64 MB), depending on the game's data pumping requests you'll be slow at most 2 or 3 times.

One hypothetic approach :
Since common key is known, a server application can be written to serve this decyrpted data to the loader.
And, If dvd read calls in the application made to the underlying system
1. intercepted, meaning there is an underlying custom firmware, then application should continue as if it reads its data from the dvd drive but actually custom firmware reads data from somewhere else.

2. patched so that every dvd read code from the game changed with an appropriate call to the custom routine to load the content from wifi-lan/sd/usb.

1: thorough knowledge of the underlying system and means of patching/cloaking it needed. Hard to implement I think.

2: I'm not enough familiar with ppc assembly and the wii hardware so I don't know if it's possible to patch the code and goof it to think that it's actually making the dvd read calls but instead it calls the custom code. Even if it's possible though it's trivial to patch the codes since there could be cases like code reads unpatched/unpatchable code and execute it.

So second one definitely is not a nice option and first one is harder.

In the end, if you do have a modchip iso loader is not a good substitute since storing the data on dvd disc is cheaper than storing on flash cards or hard drives. It could be useful for the piracy of average John who is afraid of modding his wii though.
