Spectrum ZX 128K emulator on VGA-32 board

## Hardware

[VGA32 v1.4 Board](https://www.lilygo.cc/en-ca/products/fabgl-vga32)

## What it can do

* Emulate Spectrum ZX 128K

* Load snapshot in .Z80 format from SD card

* Save snapshot in .Z80 format to SD card

* Output some sounds (partial support for AY3-8912)

* Kempston mouse

* Load ROMs from SD card (`/roms/128-0.rom`; `/roms/128-1.rom`. Fall back to OpenSE Basic if not present)

* Not using any PSRAM



## Third party software

This project uses the following libraries:

* (GPL v3.0) Display video using VGA, process PS/2 keyboard, and sound output: https://github.com/fdivitto/FabGL

* (GPL v2.0) OpenSE Basic: https://spectrumcomputing.co.uk/index.php?cat=96&id=27510

Choose one of the following for Z80 CPU emulator:

* (unsure, MIT?) Lin Ke-Fong's https://github.com/anotherlin/z80emu

* (GPL v3.0) José Luis Sánchez's https://github.com/jsanchezv/z80cpp

* (MIT) Steve Checkoway's https://github.com/stevecheckoway/libzel  

* (zlib License) Andre Weissflog's https://github.com/floooh/chips (this one seems too slow)

## Plans for the future / issues

* Flickering in some games

* Beeper

* Support noise and envelope for AY3-8912 sound

* The speed is 12% faster than it is supposed to be
