Recreates a MegaDrive boot screen and audio.
I was inspired to make this after seeing the M5Stack-Core-Grey factory test where the logo fades up, and the little jingle plays. Then when I saw M5Stack was involved in an emulator for Sonic the Hedgehog, I knew I just had to write a little boot intro for everyone! https://www.facebook.com/M5Stack/posts/2769865619915835:0
It takes only 203Kb for this classic effect, so even on a small 4MB flash version of the M5Stack core, that leaves 95% free!

The logo was a PNG converted to raw RBG565 via another online service, imageToCPP. https://javl.github.io/image2cpp/

I then used my online "Arduino PROGMEM file converter / creator V.1.0" to turn the Audacity 8 unsigned bit, 20,000 samples/s audio file into a header file for the Arduino IDE. https://codepen.io/SarahC/pen/dyWZLBG
The audio sings "SEEEEEEEEEEEEEEE - GAAAAAAAAAAAAAAA!", while the modern Sega logo fades up and then out.
