I think the DMToolbox does the formatting automatically when you compress an iso (you should do it only if it's compatible with Nintendont), though i'm not sure if it can do that plus keeping the iso as is (not compressed), or if there's a batch option formatting for that matter.
i like the idea of a monochrome one for heavy light conditions, maybe i could make it automatically switch to that with a setting that enables monitoring of the light condition through the camera
