AC Mirage has no shipped oodle library
Also for AC Mirage use 2.8.4 (same like Valhalla, both latest versions).
However fyi, for 95% of all newer games you can be safe of using oodle library 2.9.5. For the rest use 2.9.10 or 2.9.10 lib2 or even older libraries like 2.8.x (mainly ubisoft titles).
Here on this forum we have a grand collection of libraries which were collected over the years (some are missing, I have to upload them sometime).
