Greetings. What about adding graphics ported from Dune 2 on the genesis? There used 32x32 tiles for buildings, so the game look a lot better, because resolution 4 times better. (eg wind power takes on the PC version of 32x32 pixels, while both the SMD - 64x64 pixels. I understand that it's still not the same version, and it is different from the PC version. However, there are modifications to the dunes 2 SMD, which added missing the building (eg, IX center). If you need a graphics of the SMD version, it will not be a problem and the necessary graphics can be extracted from that version.
PS. Unfortunately scaling does not save the PC version of the low resolution.
