the process of manually converting each individual image (got to be over a million) is a very long process, i can batch convert them.
they maye be a way of implementing it directly into c# i mean snes emulators do it effortlessly with little fps impact, but my coding is not that good. and with mir they load single images to create an effect of animation.. where as snes games do not.. so i dont know.
i did a comparission of the sin skills, i wasnt using ERSGAN, it took over an hour to convert them, to end product i didnt notice much difference tbh. then again im using higher quality magic spell images and not the old style magics.
i do want to try and convert the objects and tiles to see how big an impact it is on environment. something i may do over the weekend.
with file size. it turned an 11mb sin magic file into a 23mb file. more than double.
and with regards to sizes of game, no it doesnt matter really in todays storage capacities...
