I don't but it seems like a very good idea.

These Teensy boards have very powerful processors with a good amount of RAM/flash memory and a uSD card socket.

Very cool C64 emulation on a 180 MHz CPU with reSID support too.

Reminds me of a C64 emulator I remember seeing on a 120 MHz Pentium in the late 90's.

Is this optimized ARM Assembly code?

The Teensy development tools is a large patch for Arduino IDE which is designed for C. It is called Teensyduino.

It is too bad this project did not evolve any further because the Teensy 4.1 can now run at 816 MHz reliably. Last update from the creator is dated Jan. 2021.

However, sombody else created this : https://blog.adafruit.com/2021/03/23/a- ... emulation/
This one includes D64 disk image support.

There is also MCL65+ which is essentially a drop-in C64 accelerator you can put in place of the 6510.

Hi eslapion,

A MCL65+ drop in replacement for the 6510 mos CPU looks very interesting. :D

I didn't know about this project.

Hypothetically speaking would the interaction of VIC II chip and the 6510 CPU (or MCL65+ replacement) hold the upper speed to a certain level?
