I have a floppy disk of Dyna Blaster and the manual. Game installs fine (it gets decompressed), loads fine, FM music plays, but the game will not accept keyboard input. I don't have the parallel port dongle that allowed you to connect two Atari joysticks or any reference card. I assume that it may expect these to be used as a default. I don't know of any command line arguments that may let the game know to accept keyboard input by default. Ironically, a hacked version that has been floating around does not have this problem.

Also, the screen raster is not entirely stable, it gets kind of shaky. I would guess this is due to the unusual, 256x232 mode the game uses.
