- On Gamecube games, there are options for scalling image - how they works? Nintendonthas option to change width, and affect games (so I can fix games that have two black lines on the right and left side of TV), USB Loader GX option to scale image seems not to work.
The same as Nintendont. ^^
In ULGX (in Nintendont settings section), when you click on "Video scale", "40" appears below. It means that the game will be rendered with 640px width.
But this default value makes the game horizontally squished as explained here by NoobletCheese :

"The GameCube video width situation is a bit of a mess imo. It seems that some developers didn't realise 640x480 internal res was going to be displayed in non-square NTSC pixels and a lot of games are horizontally squished, circles are ovals etc. You can correct it by setting a custom video width in Nintendont, but only if you know the internal res and pixel aspect ratio of the game. Here is a spreadsheet for calculating the "correct" width setting for a game if you know the values."
You can check external resolution for GC games here:

, and then choose the correct scaling value.
For example, Wind Waker is 660x448. So video scale must be set to 76, to display the good aspect ratio. Though I found 72 is better in my case, but maybe because I play on the PAL disc, forced to 480p.
Note: NoobletCheese's advise is to set values either to 54, 80 (average value), or 120, depending the game.
This is in line with Swiss predefined width values which are 654px, 672px, 694px, 720px (not sure about the last two, I have to check)
(so I can fix games that have two black lines on the right and left side of TV)
You display 4:3 games in 16:9 ? If no, black lines on sides of the image are normal (I'm not speaking of the 4:3 pillarboxes).
