NTSC
When the original Amiga was designed there were two main television
standards in use, so the Amiga was available in two versions (or could be
switched between versions): one generating the common PAL television
standard, and the other generating the NTSC standard used predominantly in
North America.
The NTSC version has a shorter display height than PAL, and a few timing
dierences that will sometimes adversely aect the operation of a program,
the majority of which were written for PAL models.
The NTSC option will switch THEA500 Mini into NTSC mode so that the
running program will act as if it is running on an NTSC Amiga.
Note: Enabling NTSC will not change THEA500 Mini’s HDMI Video output
to 60 Hz.
Adjusting the mouse speed
Programs that use the mouse will typically vary in sensitivity to its movement.
The Mouse speed setting allows you to adjust this for individual programs,
perhaps to achieve a consistent response across all programs, or just to make
some easier to control.
This is dierent from changing the sensitivity of the mouse itself, which will
aect every game equally. To do this, go to Options → System settings and
adjust Mouse sensitivity.
Conguring joystick and mouse ports
The original Amiga had two joystick ports to which a mouse and/or joysticks
could be connected. The Game settings menu allows you to specify, for each
virtual port, whether a Mouse, Joystick or CD32 pad is connected, as required
by the program.
It is common for Amiga programs to require a mouse to be connected
to port 1, and a joystick to port 2, whereas some multiplayer games may
support joysticks connected to both ports.
If there are multiple THEGAMEPADs connected to the USB ports of THEA500
Mini, THEGAMEPAD that launches the program is the one that will be
designated as connected to the rst Amiga port which is not congured for a
mouse.
