i use redump to check health of my disks by matching the md5 of your database and the one i have generated. especially when i just bought it to i don't get scammed. I don't use really that much ring code or the bca or i don't know what... i don't even know what's the purpose of all these codes... and how to obtain it...

but i have a little collection of games for wii and gamecube at least 75. including a few pricy ones... retro getting altitude for a lil' while now...

so i could give MD5 and SHA1 that i generate with a little program when i got the image of the disk.

but i don't know if it's what you demand from your "dumpers". do you want every information each time ?
or just md5&sha1 could be fine as verification ?
and even for a whole and fully new disc ?
