Introduction

I’ve been a C64 fan since 1986, and I wanted to create my very own Java implementation to celebrate the precious SID music of all the talented artists. JSIDPlay2 started as a 1:1 conversion of sidplay2 from C++ to Java and has evolved into a highly compatible C64 emulator.

Thanks to the C64 community, this project is fast, feature-complete, and eye-catching.

Special thanks go to Antti S. Lankila for continued development to enhance the emulation and adding valuable features, Nata for his numerous tests and much feedback of the beta versions, Wilfred Bos for his support and bugfix of the SIDNetDevice implementation. Other people contributed valuable pieces of code read the Credits in the player to find out. Thank you!
