    I am happy to announce pyc64 now supports save and load programs on top of real emulation. Irmen point me to the right code to look, and I implemented the fix in the weekend; happy hacking!

    In 1985, all my work started with a VIC-20 with 5Kb of RAM, and only 3583 bytes free for the BASIC. With 3 more kilobytes, VIC-20 would be able to unveil its more versatile graphic capabilities, but we have no luck. In 1995 I got a 8 MegaBytes computer with 512MB hard disk as workstation for my University Exams. I was a lucky boy, and that PC helped me to graduate up to 2000.

    Some time ago I mentioned the Pyc64 project, a “differently emulated” C/64. There’s a much more ambitious project that’s going under pressure, it’s called Commander X 16. Commander X 16 has been started by David Murray and three other guys.

    This is a VGA library for ESP8266. To use this library you need only 1 resistor and one DSUB15 connector. VGA signal generation based on https://github.com/hchunhui/esp-vga (thanks for your awesome works). [....]

    The library implement a 512x480px framebuffer with 1bpp, where each pixel is stored as a single bit. The framebuffer is stored inside RAM and require 30720 bytes.

    Ok this is a bit embarassing!

    Even in 2019, there is a IDE for C/64 which is still mantained! C64 Studio is a full .NET IDE which can connect to [Win]Vice for debugging.

    It seems Deutsche guys are very strong on C/64 Developmenet on these days….
