Jeku have you ever actually done it though?
my brother knows full well what happened to my cube when I attempted to experiment with the so-called 'methods' for getting around the protection system.
There aren't certain games, there is ONE game.. well technically it's two but it's the same bloody game Phantasy Star Online 1 & 2.
For some reason only known to the developers they not only have one of the most insecure network code known to man, but they also provide any external server access to sensitive areas of the system.
So in order to pirate in the first place you require one of those two games, that's £35 right there. Then you need a lead that will connect the GameCube to the PC.. this is actually easier said than done, as the Broadband Modem *WILL NOT* connect to a Windows or Linux DHCP network. You can see it, but when you try to access the IP and ports, you get errors all over the place.
Requires you to have a network code program to be able to talk to it. These have been created 3rd party from 3rd party SDKs... the stability of the line is about as good as an iMac's stability.
You then have to mount the image you want, and once again you have to put up with 3rd party tools to load the images of the DVD-RAM dics. This is not exactly ideal given they only recognise like 5% of all GameCube games.
Once you have one they do recognise though, your in business so to speak. Well when I say business the program will stream the disc down, and sure it'll run it... except for a minor problem.
The GameCube is designed for constant disc access, the network connection has to hack the memory to let it know to take the data from the NIC rather than the Disc.
While this all sounds grand in theory, there problem quickly becomes aparent that games were not designed to be buffered through the RAM, in and shape or form.
Playing Mario with 5 minute loading times each section, and a slow down every Nth frame was NOT fun. Even less fun was the fact that every 5minutes the GameCubes 'scratch crash screen' would appear.
For those who don't know what that is, it is a screen that says 'an error as occured on your gamecube. press reset. sorry for any inconvenience.' .. this will appear alot when your discs are scratched badly or dirty. Sometimes happens when the cube over-heats too.
So while the statement 'Games for the GameCube are possible to be pirated', there is nothing the statement saying that the results are even close to acceptable. :p
There is another method in which you can replace the BIOS with your own, but you quickly realise that the CPU itself actually has some of the OS built-in, because you get a number of error messages that appear when you try to run a game that has no protection.
The same goes for is you copy the disc from GC to Mini DVD-RAM. There is a screen that appears saying 'There is a problem found with the GameDisc, this might be because it is dirty or scratched.'
At the end of the day while it is possible, and yes I have got a version of Linux (and Windows Embedded actually) running on the GameCube, the fact of the matter is that you aren't going to see cube games sold down Bovingdon Market for a £10 each like you do X-Box and Playstation 2 games.
What it takes (and compatibility wise) to get these game pirated, until there is a viable Emulator. Piracy for the GameCube really is going to be negleable at best.
It isn't like the GBA where you can buy a kit that allows you to copy games from Cart-to-Cart. That said the Nintendo DS actually has protection against that. So now really the only way to pirate NDS games is to download them and run them on your PC.
Which let's all be honest here, playing Emulated games just isn't the same.
I know despite having a Doctor64 and copying games to my PC with excellent emulators like Project64 and 1964, I still prefer to boot up my N64 and play it on the console itself.
