Compatibility of this has improved, however there are still 2 important problems:

1) Paddle graphics are corrupt (ie. most of paddle flickers).

2) CAPS LOCK and INS keys (left and right controls for the game) are not recognized by DOSBox.

(Also the screen adjustment feature (accessible from the main menu) does not work as intended, however this one is not important.)

Apart from these issues the games work 100%.
