Kk guys let me explain to you guys something with the new loader there file there was a file called CIOS Installer that installs 249 but you already have an old version of the 249 you need to uninstall that and install the new one that wiigator provided to make it work and plus games arent working at all they get stuck at no sd codes found and plus if you are trying to use the 0.1 version with the cios installer provided you will get an error DVD identity failed

i would def like to test, i have 15 games saved on my external already, with more coming.

I would like to test it, if your still getting people. I have about 30-40 all on disc ready to test.

I'll give it a try, hopefully that will change some stuff but I doubt it will..I thought it was a cios error since everything was working until I used the installer. So fixing the installer should help make it work right?

even with installing CIOS correctly the games will not work like wiigator said some games will not pass the screen where it says no sd codes found so there is no use of testing it until wiigator finds a way to fix it

Yeah I kind of figured as much..

The DIP module from waninkoko causes some games to crash, because of the following line:

unsigned char *dvdbuf = (unsigned char *)0x133FF800; /* HACK: Ugly.... very ugly... */

This address is also used by IOS IPC. So a game can crash if IOS IPC and the DIP module uses the same address. This happens when the second race of Mario Kart is loaded.

When you don't replace the DIP module completely, you don't have a free memory address for use. DMA is only possible in the shared memory area. The problem is you can't transfer it directly to the target memory address, because the size must be a multiple of 0x800. So you could overwrite something. Also you can only specify offsets which are aligned to 0x800. The command for reading normal games doesn't have these restrictions.
So the result is, that you need to replace the DIP module completely or patch it and reuse the DIP cache.
We need to find a address which is smaller than 0x133FF800 which is only used once. Maybe we can make the IOS heap smaller.


Note: You can't use the old backup launcher, because there is no "/dev/do" device. There is just the normal "/dev/di" device.

Now i understand i will download the source and work on it see if i can find something and fix it will post soon if i find anything

@WiiGator

I have a question about how the backup loader works..
Why is it that some games work and some don't? If there is access to playing the game, then why can't the Wii just boot the game as if it was a normal one?
Do you get what I'm asking?
If theres access to booting a game in general, then why doesn't it just boot any game?

And I would also like to take part in testing the next version. I have many games in NTSC and PAL games ready for testing.

Speaking of 0.1, does anybody get the Wario Land game to work? I just get a black screen.

I hope it gets fixed eventually. I cant wait for 0.2.

An update cant find an address which is smaller then 0x133FF800 what wiigator said maybe we will have to make the IOS smaller

Hello,

I need testers for the next version. Here are some notes:
- The files are not for public release. Don't give the files to others. If anybody give it away, I will not release the source code, until it is finished. Public release will be later.
- The files should not brick your Wii. But in general before changing something in the NAND, you should dump your NAND and your keys (e.g. with xyzzy). You should also have the homebrew channel installed, so you have the ability to use SaveMii.
- The load time is faster, but not fast enough for video.
- Fixed strange bugs like the Mario-Kart second race problem.
- dvdx is not required anymore.
- DVDs need still to be converted.
- I think it will not fix games, that doesn't start at all. This should fix bugs within games.

Who have enough games for a good test?

I can test also have a chipped wii and nonchipped wii plenty of games to test currently using 0.1 launcher...... late post been
working alot at bbvideo

*edit*

sorry - just read down through the post and realised its not working properly yet.
If you do need someone else at any stage with a guarantee of no leakage from me id be glad to help with anything.

I already have a modded wii so im willing to wait on this to get sorted for as long as your willing to work on it , but if you need a hand testing at any stage i volinteer.

Guys there is no way to make this work until wiigator finds something the address i cant find it smaller and plz dont ask anymore for testing the launcher doesnt work at all like wiigator said we are not going to use that version

 

[gisel213]

Also I dont tell many people this but I am a Store Manager for Blockbuster and have access to alot of new games
that come in hell I am a big kid as they say...... I grew up on Video Games it's my thing/hobby So let's get down
to testing! thnx wiigator for your time...... when you guys find the correct or smaller address like you were sayin.....
