 Hardware Requirements
-----------------------
 
Nintendo Gamecube
NGC BroadBand Adapter
 
 
 Recommended Software
----------------------
 
GNU wget 1.8.2 or newer
You simply can't beat wget for speed under Windows or linux.
 
GNU netcat
The quickest way to get your DOL on your GC!
 
GNU md5sum
Nice and quick way to check the validity of your backup.
 
 
 Running GCOM 2.3
------------------
 
Transfer the GCOM23.DOL file to your GC in the manner that best suits you. 
GCOM2 will now attempt to automatically set the line speed for your network.
There are three modes it will try, before failing.
 
	1. AutoNegotiated 
	   This is the preferred setup, as it chooses best fit for your network.
 
	2. 100Mbps Half Duplex
	   This is second best, and offers the same throughput as option 1.
 
	3. 10Mbps Half Duplex
	   The old fallback! - Same speed as most other rippers - so don't get excited!
 
If GCOM cannot make a network connection, you may still be able to use the new
Boot options!
 
Pressing B during detect will skip detection, but your network may be
unusable!
 
 Network Functions
-------------------
 
1. Loading a DOL file
----------------------
 
To send a DOL file over to GCOM, simply use nc your_gamecube_ip 4000 < yourfile.dol
So assuming you have the default IP of 192.168.1.32, and you want to send over a
homebrew DOL, Tetris.dol for example, use:
 
	nc 192.168.1.32 4000 < Tetris.dol
 
 
 
2. Backing Up An Original GC Disc
----------------------------------
 
Select 'Backup Original Disc' from the onscreen menu. The disc will stop spinning.
Insert the disc you wish to backup in the GC, and press A. GCOM will now display the
game banner and title in the information bar at the top of the screen.
 
Use wget to capture your backup by typing:
 
	wget http://192.168.1.32/backup.iso
 
Obviously, substituting the IP you have chosen!
 
 
 
 Boot Game Functions
---------------------
 
If you want to test a backup made with GCOM, select 'Play Game Backup' from the main 
menu.
 
GCOM will stop the disc spinning, and prompt you to insert your backup disc.
Press A, and GCOM will try to load the disc for you. 
 
I have left the default option of forcing PAL/NTSC on the boot menu, but in reality,
they are pretty pointless! Very few games accept being in the wrong video mode!
 
However, this pause is useful if you intend to use Action Replay or GCNRD. 
 
You can also play games created with VMBIC, COBRA Multiboot Discs.
 
 
 
 Z PAL Mode
------------
 
I added this to allow GCOM to be forced to PAL mode, if it's detected incorrectly
on your system.
 
Just hold the Z key as GCOM boots, and PAL mode will be set.
 
 
 
 Load DOL from DVD
-------------------
 
This should be pretty self explanatory. When prompted, insert your ISO DVD and
follow the prompts until you are at the file browser.
 
Highight the dol you want to run, and press A.
 
 
 
 Known Limitations 
-------------------
There is a limit of 1000 files per directory in the browser.
 
Use X/Y to fast page up/down.
 
 
 
 A note about NICs
-------------------
 
Your GameCube comes with a pretty poor Macronix NIC, so you're starting off with
a not-so-great base. 
 
The choice of NIC you buy for your PC makes a huge difference. I'd recommend 3COM
or Intel, as these seem to work just fine.
 
Don't expect a cheap Realtek or D-Link to come close. The 2 quid you saved on those
would have made a huge difference now !
