The PC version on Steam is based on the mobile version.
Although I know there was efforts being made to improve the PC version with mods. Anyone know if much progress was made?
Modders removed the garbage filter/scaling that Square implemented for the PC/mobile versions which actually significantly improved the new sprites and look of the PC release.
People were looking into replacing the sprites with the original SNES versions, but Square encrypted those files so it's taking some time. I don't know where to go to see progress on that mod.
