A port of the rott-engine from Puck2099.
change on v0.2:
* Fixed sound problems.
* Added game music.
* Added TVOut autodetection so now it isn't necessary to have 2 programs for each version.
* Increased clock speed from 133 to 166 Mhz. It isn't too bad at 133 Mhz, but in maximum difficulty level it could slow down a bit when the screen is full of enemies.
