Hacking About External DVD reader

[ferrazoli]

So I'm tried to use DVD backups (burnt ones) on my wii, but I'm using it with a external dvd reader
cos my internal broke

AND
I do NOT have a SD card

Any channel I can install?

 

[Lucif3r]

Channel for what?

 

[ferrazoli]

Reading the disc in my usb dvd drive?

 

[Lucif3r]

The wii doesnt support reading from external DVD natively, you will need a homebrew application that can do that. That means you need to get an SD card for ~10$.

You can use uLoader. It works well with a USB DVD drive, although it looks very early 90s .

 

[Lucif3r]

But uLoader still needs to be installed on an SD card, right?

 

[fig2k4]

Yep, my answer was in addition to yours. I should've made that clearer.

I wonder if fat32 from a dvd would work.

Does HBC work with sectors != 512b?

 

[fig2k4]

You mean actually formatting a DVD as FAT32? If an image is created first and then burned to the disc in raw mode, it would only require the software to be able to read it. But that doesn't answer your question.

I was wondering the same thing about making multiboot discs using a WBFS partition burned to disc. That could be very handy for backups. Much easier to implement too I think.

uLoader already does something similar to this, allowing the use of CISO discs.

 

[PsyBlade]

Yes that was what I was thinking.
Only with an MBR too. I dont think many wii tools like unpartitioned disks.

The idea was that it might not need special software support, via USB Mass Storage everything should look like the same blockdevice anyway (only with 2kB sectors ?).

I've sent an PM to you, I can help you, talk with me, I'm brazilian too and I use uLoader

I'm new to this world,
tell me if this model is compatible to read backup LG GP10N

It doesn't. It will recognize an optical drive as USB storage but crash when libfat tries to read the first sector (2048 bytes) into a 512 byte buffer (this has been fixed in SVN).

Writing a FAT image to a disc would be an adventure... you would have to build the image using a temporary FAT filesystem with 2KB sectors. Presumably it's possible to set the emulated sector size when using a file as a loopback device in linux, it's been a while since I've done it.
Lack of an MBR shouldn't be a problem as long as the partition starts at sector 0 (most SD cards don't have them).

 

[PsyBlade]

loopback can't set sectorsize afaik
but mkdosfs does work on files and can override sectorsize via argument
as can fdisk and wwt

but so far my tries it failed
1.mbr(fat + wbfs) on hbc, cfg, gx
2. no mbr wbfs on cfg

since I don't know where my RW disks are and the dvd is based on a borrowed usb-hdd anyway, I think I leave it at that
