Welcome to gimp-forum.net
1. Set up a 128x64 pixel canvas and in the advanced options break the link between X and Y resolution then make the X resolution x2 the Y resolution. If needed Gimp can do the arithmetic but it is just twice. screenshot: https://i.imgur.com/RVCOXrL.jpg
2. In the view menu untick the Dot for Dot option. https://i.imgur.com/CIrQ5ws.jpg
3. That gets a square canvas to work on. Note it is still 128 x 64 pixels that does not change. Some elements (curves etc might look a little fuzzy because of the interpolation (- the price you pay) https://i.imgur.com/nUOBRVr.jpg
4. Finished. Turn Dot for Dot back on. Save you work as Gimp .xcf which keeps layers, guides, masks. Export the image in whatever format the controller firmware uses. https://i.imgur.com/dwGvHtm.jpg
