Hi Justn,
Unfortunately, the upscaled version of Minifantasy isn't being worked on. I am still expanding the classic Minifantasy collection monthly, but the upscaled project was put on hold due to not having enough demand.
However, if you have classic Minifantasy asset packs (or any other low-resolution art you want to upscale), it's not difficult to get the assets upscaled yourself using this free tool created by CokeAndCode:
xBR is a pixel art scaling algorithm that scales by rules. It was developed by Hyllian in 2011, mainly as a scaling filter for video game emulators.
CokeAndCode's tool uses this implementation.
I hope this helps! Have a great week!
