you have to add the commandline parameters (CMD) to attract.
If you want to start a game directly from commandline or a batch-file, you have to use this parameters:
path_to_nestopia\nestopia.exe path_to_romfile\my_nes_game.nes
in my case:
C:\attract\EMU\nestopia\nestopia.exe C:\attract\EMU\nestopia\ROMS\my_nes_game.nes
in attract:
executable C:\attract\EMU\nestopia\nestopia.exe
args "[romfilename]"
rompath C:\attract\EMU\nestopia\ROMS
romext .nes
