Difference of roms between the page of the systems included and the one of a single system
When introducing the roms of Atari2600, in the systems page, under the icon, it puts 646 roms.
And when I enter the Atari2600 system, it puts 642 roms up.
Why does this happen? Can the roms be wrong?
Is not there a way to know what files you have not found, to correct them?
