Cannot Activate Achievements Using Sameboy Core

Using RetroArch 1.8.4 and SameBoy core 0.12.0 (the latest version per my updater), I’ve noticed that I am now getting an error message: “Cannot activate achievements using this core.” This seems to be happening with any game in the core. I did see on the SameBoy website that some issues with achievements were fixed with version 0.12.3. Is this something that will be resolved when that version is eventually ported as a libretro core or is there something else at work here?
