Non, je confirme, je ne pense pas m'être trompé en telechargeant le romset. Je viens de vérifier, et pour la n64, la team indique bien ceci :
7zipped and merged: Nintendo - Nintendo 64 Nintendo - Game Boy Advance Because the N64 and GBA sets are so huge, they are merged to drastically reduce size and download times. This means ROMs of the same game but different regions (US,Europe,Japan, Etc) are archived together allowing the data they share to be compressed even more. You may want to extract the games you want to play since most emulators can't read the 7zip format directly.
