SameBoyT4

Port of SameBoy to the Teensy4.1 microcontroller.
This was just an educational exercise. All features of SameBoy are not implemeted. The performance is okay, but certainly not 100%.

• Load ROMs/saves of the SD card. Currently filenames are hardcoded.
• USB input driver (hardcoded for Xbox360 type controllers)
• Save and load SRAM (Press Y to save)
• Audio supported!
