Retro Games THEA500 MINI - Auto Crop and Easy Size Optimization

23
To set the Crop rectangle correctly it will usually be necessary to repeatedly
suspend the game, adjust the Crop rectangle and then resume the game to
make a visual check. It is therefore recommended that you enable Screen t in
the Display options menu when performing a visual check, since it will make it
easier to see when the settings are correct.
To make this conguration a simple and often one-click process, THEA500
Mini also provides an Auto crop function.
Auto crop
This function attempts to automatically set the size of the image to minimise
the black borders shown at the top and bottom of the screen (particularly
when using the Screen t display mode).
The Auto crop function is only available for a game that is currently
suspended. In this case an additional button Y for Auto crop will be shown at
the bottom of the Game settings menu.
When activated, the Auto crop function will analyse the image at the point it
was suspended and automatically calculate the Crop rectangle and position.
This is nearly always successful and only occasionally requires a slight tweak
to the settings afterwards.
Setting the image size the easy way
A quick and eective procedure for optimising the size of the image is as
follows:
1 Select the program to launch from USB stick
2 Enter Game settings
3 Enable Auto centre
4 Congure the mouse and joystick ports (see "Conguring joystick and
mouse ports" on page 24)
5 Launch the program and proceed to the main game play screen
6 Suspend the program by pressing H
7 Enter USB Media Access → Game settings
8 Activate Auto crop by pressing Y
9 Press B twice to return to the game carousel
10 Resume the program by pressing H
If you nd that the image moves around too often with Auto centre
enabled, repeat the procedure but instead disable Auto centre at step 3.
