MiSTer supports 1200p. The DE10-nano–which is what the MiSTer project is based round–maxes at about 1600×1200 realistically according to Electron Ash, and Rysha showed off screenshots of the NES core 5x integer scaled. It looks great if your display supports non-standard resolutions, and it will scale perfectly to 4K in the future. 5x scaling is still experimental and is not officially supported by any cores yet. Consider this a tech demonstration for the foreseeable future.
