Atelier Rorona Plus The Alchemist of Arland [BLES02050]

It is kd-11. And you can use the latest RPCS3 version now, those changes have since long been merged into master branch.

so if i get it right... the latest build that you mean is this (april 12)
https://ci.appveyor.com/project/rpcs3/rp.../artifacts

it already has the k-11 merged and all i have to do to try to make trails work is to use that build and check GPU texture scaling? of course i assume that i still have to follow everything else you thought me: the sandy bridge, the check all modules, and the firmware from sony, ... right?

i think i tried that but i'm still getting an error. if this is confirmed then i'll try again and then attach the log. vulcan and d2d... whatever, and i should use both recompilers?
