Support for the machine-translated translation of Trails to Azure will no longer be provided on GBATemp after Guren releases his English patch.
Please check here for further support on the unedited Trails to Azure patch by Guren: http://gurennoheyakara.blogspot.nl/p/games.html?m=1
Please check here for further support on the edited Trails from Zero patch by the Geofront editing team: https://geofront.esterior.net/
It is very unlikely that an official localization will be done by XSEED, but the Geofront editing team know what they are doing, and making things consistent with XSEED's translation of the Kiseki/Trails series. Please show your support to the Geofront editing team.
