**Project name is now changed to KungFuSID: https://github.com/Sgw32/KungFuSID
Open source SID 8580/6581 emulator that can be executed on Kung Fu Flash and new Kung Fu SID hardware
License - GNU General Public License v3 (derived from Bakisha STM32 SID player)
Project is heavily inspired by SwinSID and ArmSID project. And is maintained as an open-source alternative to them. Now it is even working on a GD32F405RGT6 on 168 MHz with 8 MHz crystal, just like Kung Fu Flash - and firmware is using critical code from KFF. I'm looking for contributers(I can even pay for the work) who will add some assembler optimization magic into SID code.

Swinkels page - dead http://www.swinkels.tvtom.pl/swinsid/ Available on Archive.org - please check it, there is a SID emulation source for SwinSID atmega8515.

Kung Fu Flash - https://github.com/KimJorgensen/KungFuFlash I am inspired by simplicity of it and its power.

Special greetings to Protovision Games
STM32F103 has a very long delay between CS fall down and interrupt routine begin - about 200ns. With a 500 ns window at all. I plan migrating to STM32F405RCT6(still, very cheap on Aliexpress) my PCB also supports it. Also, I should optimize RW&CS routines to enhance performance.
- ADSR attack works somewhat slow
- Data readings are not correct at event-intensive tunes(where there are a lot of write-to-SID activities)
- No 6581/8580 switch
- No paddles(can be done though)
