May 13th 2021: C64 emulator improvement for PICO
- Overclocked to 250MHz for better speed
- Add on screen keyboard for text input
May 2021: few improvements for raspberry pi PICO
- VGA driver stripped down for 8bits RRRGGGBB (red lines bug fixed)...
- Improved PWM audio...
- Add sound to C64 emulator but still running far too slow
- Add SID player application (picosnd)
April 2021: Add initial support for raspberry PICO
- adapted pico scanline library for VGA 8 bits mode (RRRGGGBB), sorry adapted code is embedded...
- SD support from https://github.com/carlk3/no-OS-FatFS-SD-SPI-RPi-Pico (fixed IRQ to 1)
- rudimentary PWM IRQ based audio (https://gregchadwick.co.uk/blog/playing-with-the-pico-pt3/)
Far from perfect, lot of bugs, and ... unfortunately C64 emulator has no sound for performance reason!
All what you need is in MCUME_pico. Precompiled binaries in MCUME_pico/bin.
To recompile, look at MCUME_pico/readme.txt

Mid October 2020: Most emulators are now supporing VGA with sound on the Teensy4.1
Experimental I2S sound driver has been added to the VGA_t4 library with minimal DMA disturbances.
If you are experimenting issues (e.g. image flashing out, crash after few minutes):
- try compiling for smallest code iso faster
e.g.:
- ST emu: compile for "smallest code"
- Amiga emu: compile for "smallest code"
- Doom: compile for "faster"
Atari ST emu has now better sound support!
October 2020: DOOM ported to the Teensy4.1 (for VGA and LCD displays)
No sound yet but with USB keyboard support (see VGA prototype PCB below).
