first time maybe you need to set up direction of translation from Chinese simplified to English and also sometimes I randomly experiencing it will reset iself to ENG>ESP, dunno why
Do you want the update only if so: http://www.multiup.org/fr/download/3b39e680aef11ed1b592de52ac9a123b/0004000e00196d00_v2.2.0.cia
Apply that update by installing the cia on the japanese version, it's the only mirror I found so sorry press on telecharger to download it.
Oky doke, I dug around a bit deeper.
I found some direct downloads via 3dsiso.
Pokemon Omega Ruby - EUR - 1.8GB - If you use 1Fichier, the download is on the bottom.
Pokemon Alpha Sapphire - EUR - 1.8GB
Both files are Tar.gz. WinRar should be able to open them. It'll take roughly an hour for me to finish the download and scan myself.
