Hi folks, this is my first post and I'm not sure if links are allowed to certain "dodgy" sites so I won't post any unless I'm given the OK. I've been looking into dumping Wii games and tried Waninkoko's DVD Dumper and WiiHTTPd. Both gave me incorrect checksums so I was looking for something else when I found a new Wii homebrew app called Superdump. This can dump a single layer Wii game to a FAT32 partitioned USB hard drive in less than 20 minutes, much better than the 2.5 hours or more that the WiFi dumpers take. It also supports GameCube games and dual layer Wii games - it only took 28 minutes to dump Brawl. So, here's a little guide to the process I'm using to dump games:
You need:
A Wii with Waninkoko's cIOS installed as IOS249. It turns out that the reason the other dumpers gave me incorrect checksums was that I was using rev14. There's a bug in it that makes it stop dumping at 99%, so I'm using rev13b now and it's fine.
A USB Hard drive (or memstick, SD card adaptor etc.) with a FAT or FAT32 partition of at least 5GB (8GB for Smash Bros. Brawl and, I assume, Metroid Prime Trilogy). I've got a 32GB FAT32 partition on mine with a second partition for USB Loaders.
Superdump 1.3, Google superdump wii and you'll find the thread where I found it. The link to v1.3's at the top of page 11.
Sometimes it fails to recognise my HDD in which case I just exit back to the homebrew channel and load my USB loader of choice (USB Loader GX). Then I just quit back to the HBC and try Superdump again.
Once the dump's finished, plug the HDD into a computer and piece together the ISO. Since it uses FAT32, it can't fit a whole DVD image in one file so you need to append the files it creates to get the whole iso. In Windows, just do: copy /B <part1> + <part2> ... <full path to destination .iso file>. So for example PAL Metroid Prime 3 would be:
copy /B RM3P01_0.bin + RM3P01_1.bin "E:\wii\Metroid Prime 3 - Corruption (Europe) (En,Fr,De,Es,It).iso"
Hopefully this will be of help to the Wii dumpers out there, it's certainly a much, much faster way of doing it
