Waste Of Memory
Most of the memory slice which has been dedicated to the graphics has been wasted to uselessly keep the main ship from 3D Quasars and the mountain in the background of Monkey Magic.


Six Titles Debut
Alien Attack has been arguably released at the same time with Quick Draw, Cruncher, Knock Out, Mission Mars and Suicide Run in the very beginning of Solar Software: all the titles show a loader screen in the respective no turbo versions where all the six names are displayed.

As reported in Commodore Horizons 21, Brenda Shay talked about a routine coded by John P. Shay which was capable to convert the games straight from the VIC20 code, then she named exactly these six games.


All these titles have as original starting address $2100. All of the titles have been saved thru Novaload versions on Triple Decker series including some useless memory filled with garbage till $3FFF, although all these games occupy $1001-$3000 only, and starting from a code located in $2050 which awaits some seconds before jumping to the original starting address at $2100.

Alien Attack exists in three different releases: no turbo with loading screen, turbo starting from $2050 named "Alien", turbo starting from $2050 with the same serial but as "Alien Attack"(Triple Decker 5).
Alien Attack turbo on Triple Decker 5 forgets to clear the screen at Novaload, leaving the Novaload string over the titlescreen.
