I know than the resolution must be 256x240, but can we make for example 512x480 and rescale all the sprites to x2? Or is only allowed to 256x240?

God luck to all!

I think it's a given that we'll be up-scaling our graphics, as long as the source pixel resolution is 256x240.  

I came to ask the same thing! It's just not feasible at all playtesting 256x240 on 1440p+ monitor lol

DoombladeZero Exactly is my problem, and whit my farsightedness it's complicated XD

I assume there is no problem, it's just to be sure
