Hi all! I've found this topic very useful for making my mixes, and I want to use it to post my problem creating my own mix.
I've created 3 different Mix Profiles, one to scrape EUR roms, one for scrape USA roms, and one for scrape JAP roms.
This is my config.ini that I've created:
[MIX_IMG]
$MIX_IMG_NAME = PersonalStyleUSA
$MIX_IMG_EXEMPLE = exemple.png
$MIX_IMG_CIBLE_X = 600
$MIX_IMG_CIBLE_Y = 400
$MIX_IMG_NBIMG = 5
$MIX_IMG1_SOURCE_1 = 'screenTEMP|GameMax|medias/media_screenshot|path:image|476||119|8|'
$MIX_IMG2_SOURCE_1 = 'wheelTEMP|GameMax|medias/media_wheels/media_wheel_us|path:image|320|320|RIGHT|DOWN'
$MIX_IMG3_SOURCE_1 = 'boxTEMP|GameMAX|medias/media_boxs/media_boxs3d/media_box3d_us|path:image|269|269|LEFT|DOWN'
$MIX_IMG4_SOURCE_1 = 'cartridgeTEMP|GameMax|medias/media_supports/media_supports2d/media_support2d_us|path:image|150|150|LEFT|CENTER'
$MIX_IMG5_SOURCE_1 = 'flagTEMP|FixeMax|Lang-USA.png|path:image|100|100|UP|LEFT'
The problem is that in many roms I'm obtaining a correct scrape like this:

But many other, I'm obtaining a wrong rendered file, like this:

In this picture I've lost the cartridge and the logo images (and both of them are in screenscraper.fr database...)

And I've lost the logo in this other (and also, the logo is in the screenscraper database...)
I don't know what it's hapening, because in many cases, the rendered file is correct (as you can see in the Super Mario 64 scrape...), so the config.ini it would be correct, right?
Please, can anyone help me with this?? 
Thank you very much!!
