GC Backup Launcher for Wii by WiiGator
######################################

Package name: GCBackup

What it does
############

You can start GameCube backups on Wii. There is no hardware change required. This is only software.
There is only DVD-R directly supported. DVD+R need to be patched to booktype DVD-ROM.

Installation Guide:
###################

1. Copy directories "miospatcher" and "rungcbackup" to your SD card into the "apps" directory.
2. If you don't have a internet connnection with your Wii. You need to copy only one MIOS version to the SD card.
3. Put SD card into the front slot of your Wii.
4. Start Homebrew Channel
5. Run MIOS Patcher and press A (GC controller).
6. Insert your GameCube disc.
7. Run GC Backup Launcher and press A to start game (GC controller).

Note: If you want to start a game from the Wii disc channel, you need to enable support for Wii Backup Launcher by pressing in step 5. You can use rebooter from the Wii Backup Launcher to test it.

Compatibilty
############

Some games are not working.

How it works
############

MIOS is patched to allow starting of homebrew. It is also patched to leave DVD-R support enabled.
The rungcbackup.dol copies the gcbackuplauncher to memory and changes to GameCube mode.
gcbackuplauncher patches the DVD read functions, so reading is possible.

System requirements:
####################

IOS249 with backup support need to be installed (e.g. my cIOS r7 from backuplauncher 0.3 gamma).

Additional Information:
#######################

If installation fails with error -1017. It will try to delete MIOS and install it after (files are already downloaded at this point). Deletion will only work with a custom IOS249. So if you get error -1017, you need to install IOS249.

Note 1: Changing to GameCube mode is sometimes not working. Turn off Wii and on again and retry, if screen looks strange.
Note 2: Starting with patched MIOS enables MIOS to load the game, but the game is not patched. This is only working for homebrew DVDs.
Note 3: DVD speed is still limited to 3x.
Note 4: There are sometimes problems with the DVD read speed. So there is sometimes a very short delay in a few games. The game play is only barely influenced.
Note 5: If patching of DVD read function fails, the game will still be started. If the game accesses the DVD, there will be an error.
Note 6: On read error there will be 30 read retries. I don't know if this works, because I don't have such read problems with my DVD-R brand.
Note 7: If you eject the disc, no disc can be detected after it. For 2 disc games use the second disc to boot, if you need to change the disc.
Note 8: If Wii Backup Launcher Support is activated in MIOS, the Wii Backup Launcher can start the game. It is also possible to start the game from the disc channel, if the rebooter is used.
Note 9: The power off button will reset the system. It will work, when you start the game from the disc channel.
Note 10: You need a GameCube controller to play games
Note 11: To save a game you need a GameCube memory card
Note 12: Switching between different regions may destroy the data on your memroy card.
Note 13: Modchips are not supported by this Software.
Note 14: This Software runs only on Wii and not on the GameCube.
Note 15: This Software is started in Wii mode and switches to GameCube mode.
