I'm personally one of those guys who ordered that LG drive when Wii disc dumping was first developed. For those who don't know, LG drives supported are LG-8164b and LG-8163b (possibly some others, but these two are known). And the application used to dump games is called RawDump: http://gbatemp.net/index.php?download=1769
Also, this is what I have read about legality...
It is illegal to download any copyrighted video game from any source for any amount of time regardless of whether or not you've purchased the game at any point in time. The only legal way to own these games in formats such as ISO is to back up the game yourself. Even if the MD5 hash matches an ISO you ripped yourself with an ISO someone else ripped, you're not allowed to take the ISO from the other person.
Technically though, it IS legal to download ISOs from the internet... but only if you ripped it yourself and uploaded and are redownloading what you uploaded. :p It's a matter of who ripped it, not a matter of what data the file contains or where the file can be taken from.
