Another World in Flutter
summary
A source port recreates the 1991 cinematic platformer inside Flutter by interpreting the original bytecode (the VM uses 256 variables and 27 instructions) and rendering vector polygons to Flutter’s canvas via a custom display list double-buffer system. Original assets and scripting stay unchanged, audio runs through FFI to a C library/SDL, and GPU replay of draw commands keeps performance acceptable despite losing Amiga palette tricks; the result is a playable, upscaled recreation with some palette and shader limitations.
