These are unstable (crash-prone) super-super large maps that go way beyond the 255x255 limit (the former largest map). The map sizes are 512x512, 768x768 and 1024x1024 tiles. They are not meant for serious scenario designing and merely a curiosity.
RoR only (.scx).
For more info about these maps and their weird properties, see this forum thread.
