I've rebased the ff14-launcher-9.x branch on wine-9.9 and confirmed that it works correctly as modified. wine-9.10 includes changes in dlls/mshtml which conflict with some of these changes
Looking at your branch, current Wine should already have alternatives for almost all features. While CC/GC integration is still missing, it shouldn't block functionality, it may just lead to OOM issues over time. Legacy constructors are also unimplemented, though they are irrelevant in this context. If any other fix is still missing, it would be interesting to know what exactly.
