What is a Gamecube?
The GameCube is a video game console made by Nintendo. It’s marketed audience is children, yet many adults who grew up with the big N have come to enjoy it.
Nintendo’s Official GameCube Page - http://www.nintendo.com/systemsgcn
Currently there are four main retail versions of the GameCube. The “DOL-001”, “DOL-002”, “DOL-101” and the “Panasonic Q”. Please see the Gamecube BIOS Chart to see which BIOS work on your system (only the Cobra and/or Qoob BIOS will work on your Panasonic Q)
This is a picture of the infamous Panasonic Q. It’s a combined DVD player with a GameCube in a really cool custom case.
Buy one for $250 on http://prodb.matsushita.co.jp/product/info.do?pg=04&hb=SL-GC10
There is no BIOS support in older BIOS and/or Anaconda for the DOL-002, DOL-101 and/or Panasonic Q. Make sure the unit you have is DOL-001 if you wish to use an older BIOS. DOL-001 has two AV ports on the back (one analog and one digital).
NOTE: The DOL-002 version of the GCN is an exclusive version to Brazil. It was manufactured by a Brazilian company, Gradiente, due to a now dead partnership between Gradiente Nintendo.

There are two version of this IPL, they are all for NTSC units. One is for DOL-001 and the other is for DOL-101 both versions do have the same version number but not the same release date and are not compatible each others, thats one of the reason of the numerous bugs from Cobra v0.2, v0.3 and v0.4 with DOL-101 units.

I know it can help or interest some people to have that IPL Version guide and know more about those, however only Retail IPL Versions are mentioned here, don't look for details on the TDEV or NPDP GBOX IPLs while looking at that post.
There is also a modified GameCube that reads DVD videos that is called the Panasonic Q and that is only being sold in Japan, however I don't know what IPL Version it can have, I heard someone has a V2 IPL in his Panasonic Q, however the Panasonic Q is just composed of a Panasonic DVD player mainboard, a GameCube mainboard (a Japanese DOL-001 Retail version) and a (VERY) modified v8 Drive (that only has v8 in the drive version but that is totally different from standard v8 drives). It also uses two different drive controller chips, one for DVD and the other for GameCube and the GameCube controller will never allow to read more than 8cm medias (no full DVD reading on the GameCube mode as it's hardware limited by the controller chip), however the Q can be much less picky with media then standard GameCubes.
