This config file is used to set a different game or channel ID from the real one for when downloading covers. This way, you can redirect GameTDB/WiiTDB downloads to another cover if the cover for your game or channel ID isn't found, or if the other region cover is better.
WiiFlow does not make this file, you will have to make it yourself by making a text file and naming it newid.ini when you save it.
Note: When creating this file there must be a blank line at the top of the file before the first section
This file contains two sections, a GAMES and a CHANNELS section. Every line specifies an old=new value.
For example, the following will get the cover for the new homebrew channel, even when you have the old channel installed
[CHANNELS]
HAXX=JODI
The following line will get the NTSC cover for the PAL version of Call of Duty: Modern Warfare:
[GAMES]
RJAP52=RJAE52
This file must be placed in the settings folder, which has a default location of /wiiflow/settings
Note: this will not work for plugins and homebrew. It may work for GameCube but I have not tested this.
