ned needs to be compiled for interactive mode by changing the
corresponding line in pkg/ned/server/src/Makefile to add readline
support. python is also in the pkg dir. The actual graphics comes from
the fbterminal, i.e. one needs to connect input/output of the
interactive programs with the fbterminal. Supertux itself isn't in the
repo, but all the adaption parts are in libsdl, which is there.
Supertux itself is not modified at all.
Starting a terminal with a program in it could go like this, extending

function start_with_terminal(e, res, p)
  local c = {
              fb = mag_caps.svc:create(L4.Proto.Goos, res),
              term = l:new_channel():svr(),
  l:start({ caps = c }, "rom/fbterminal");
  e.log = c.term:m("ro");
  l:start(e, p);

start_with_terminal({}, "400x300", "rom/ned -i");
