I made a Lua script for BizHawk that allows you to view your entire city at once in Sim City for the SNES. Lua script: / simcity-snes-map-71239703 BizHawk emulator: tasvideos.org/...
No, sorry, I'm not going to remake this for other emulators. All of its LUA source code is there, though, so if you're capable of writing scripts you can apply the same methods found in that code to your preferred emulator.
