These actually come w/ both 16x16 and 48x48 variants. For RMMZ projects, I don’t use the native sprite size options to make the 16x16 plug and play. I upscale everything 3x and it just winds up looking better.
Anyways, these scale perfectly and retain pixel perfect format as long as you’re not mashing them w/ other resolutions.
I don’t know Phantom 2040 but maybe I’ll have a look at it next time I need some mech inspo!
