ATARI MODEL
This option allows you to select the Atari home computer model on which you wish to run the selected program. The default
is the Atari 800, as a great many programs will run on this model. Changing computer model will aect the control type
options that are available.
ENABLE BASIC
This option selects whether a virtual BASIC cartridge is to be installed when running the selected game. It is only required for games
which use BASIC, or you wish to use BASIC yourself. See “Accessing the BASIC programming language” [page 29].
ADJUST THE IMAGE POSITION AND SIZE
Many programs do not utilise the full horizontal or vertical resolution of the Atari display and therefore can have a black bor-
der around the gameplay or not centre it vertically. This will be most noticeable when displaying gameplay within a graphical
border (See “Choose frame” [page 15]). Also it is common for the game display size to change while the program is
running, for example the game attract screen shown before you start a game can be a dierent size to the gameplay itself.
With the default display height of 200 and vertical oset of 20,
Missile Command shows black borders at the top and bottom.
By altering the settings Display width, Display height and Vertical oset you can tell THE400 Mini the size of the gameplay
image you want it to show for the game being congured, to remove any black area around the display image.
Setting the display height to 194 and adjusting the vertical oset to 24,
Missile Command displays fully without any black borders.
