Previously only new ROM loading operations would take into consideration the auto-mode.
This fix affects the SDL frontend only.

In the SDL version.

Created infrastructure that allows the usage of the serial device to capture the result of the tests.
Then the test is executed agains a pre-defined number of cycles and the result is compared against expectation.

This makes it possible to select CBG or DMG mode taking into consideration the CGB flag in the ROM file.

With initial approach for scalling down the speed of other components.

Created more panic conditions for the KEY0 and KEY1.

The background attributes seem to be failing.

Will allow much better debug.

Allows for more flexibility passing command line arguments.

Still pending processing and conversion to RGB8888.

Still requiring a lot of operational work to allow proper working.

Callback is done using a global window function.
Printing is performed to the console output.
This is still a work in progress and the final display of the image should be included in the Web interface.
