I don't have Atomic under my eye here.
So i will answer you better later. but :
Concerning the alphabetical order, it seems i have a bug somewhere in my sort routine. The Tetris is in the "A" because his rom name is atretris.zip , that's not normal it is in the A because the module should sort on game title and not on romname. I will investigate that. For now the work around would to build a already sorted gamelist instead of let Atomic sort it. But i will check that.
For the other too point, it is possible. but here too, it is by building your own game list and exclude list.
If you look in <atomicfe>\plugnplay\arcade_simple\roms folder, you will see in addition of your roms 3 .TXT files :
FullList.txt
gamelist.txt
excludeList.txt
FullList.txt is the file that contain translation of romname to title . ( a kind of dictionnary , if you want change the displayed title for a game you can modify this file).
gamelist.txt is the list of games that Atomic will display, if the rom is present.
excludelist is the list of roms that Atomic won't display anyway (even if in the gamelist.txt , generally it contains BIOS roms)
AtomicManager provide you a tool to generate gamelist and excludelist, based on some ini file to allow to filter game quickly.
if you open the file :
<atomicfe>\plugnplay\arcade_simple\arcades.cfg with AtomicManager , you should see a "GameList" tab , it is where you can build your own gamelist.
Do you know that there is a official support forums for ATomicFE in English ?
