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.

The solution makes use of the chrono module to obtain time and the image module to save PNG files.
The Web version is still pending support for printing.

The image data buffer printing is still pending.
Still a lot of TODOs and edge cases to be solved.

APU enabled getter was not being correctly called.

This allows better understanding of the ROMs and their purpose.

Support for set of video, audio and timer.
Now with support for toggling audio in the SDL version.

Now the BIOS beep works perfectly.

The emulator is now sounding more like a real audio player .

Made use of queue support for SDL avoiding the callback approach which greatly simplifies the code and increases the APU accuracy.

It's stil glitchy and noisy, need to check the problems.

Still requires work to be able to be able to emulate APU together with the CPU instead of inverting the control.
