Chimera: hidden game

As you know, In Chimera there is a hidden game that is activated after pressing bar space (pause) and then start+select+option.
However never I've been able to play it, always crash it (in different emulators and real hardware).

Only with an old emulator a helicopter appears.

Is there a dump which can play correctly that hidden game ?

Although in Wikipedia says: "Unfortunately the bonus game crashes on the Atari 800 due a programming error."

The good thing is Fox was able to do q quick fix for it:

Cool! Looks like the game code is corrupted, at least in Chimera (v1).atr from atarionline.pl. Quick fix in Atari800 (Win PLus): enter monitor, type:

   c 5005 8d
   f 5080 509f ea
   contNow run the hidden game

And an screenshot:

Now Tezz has fixed to have a final executable chimera game with playable hidden game: http://devwebcl.atarionline.pl/fix/chimera_tezz_fixed.zip
