I'll get back to you shortly. How do you (what technique) upscale the files? The unit sprite sheets arent' trivial, it's easier to ask YuokiTani to just re-render his 3D models into higher res. His objection to that, was that the units are designed (their detail etc) for lower res. Higher res will look boring, maybe needs more Greebling or something to keep them interesting/higher detail.
