Yep! Specifically Omega Ruby and Alpha Sapphire, remakes of the generation 3 games. It introduced “Primal” forms of the legendaries Groundon and Kyogre which is what you see in the image. It’s supposed to be them at their peak power.

Windows users could boot into safe mode and modify/delete the problem file. There just wasn’t any tool to roll out this fix ‘automatically’.

Once IT dealt with it I stopped paying attention to the situation, but I wonder if any tool was created to help the poor souls managing thousands of PCs?
