Kung Fu SID GD32 version
IMPORTANT! Firmware is adjusted for new Kung Fu SID hardware (and only)
Introduction
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.
A firmware for Kung Fu Flash and Kung Fu Flash GD32 which emulates SID via internal DAC of STM32F405RGT6 All hardware files are copied from "UltiSID" , projects are merged. Original UltiSID firmware is obsolete and current Kung Fu SID firmware just is partly based on it in IRQ and SID emulation.
You can test Kung Fu SID by compiling firmware and flashing to your kung fu flash.
To use it with original KungFuFlash cartridge output - check previous commits. Now only KungFuSID hardware is supported(and devices are selling)
Example usage with MixSIDs (you can use it directly, of course)
Patched by avrem for GD32F405RGT6 microcontroller. Patch includes:
- ARR timer fix for GD32
- Memory remap fix (since KFF is running from RAM)
You can use both GD32 or STM32.
Future plans
I need to finish paddles, 6581-8580 switch and make a bootloader(optional, though). Probably, that's it and project will be finished. Some tunes still require some improvements, e.g. Artillery Credits by Geir Tjelta
Limitations
- No 6581/8580 switch
- No paddles(can be done though)

Questions
How big is the KungFuSID PCB?
It measures 17.5 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the KungFuSID use?
35 parts, built around the GD32F405RGT6, LM321, AMS1117-3.3 and 1N4148WS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the KungFuSID KiCad files?
From the Sgw32/KungFuSID repository on GitHub, at the commit this page was made from: the board is hardware/KungFuSID.kicad_pcb and its schematic hardware/KungFuSID.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KungFuSID design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sgw32 before reusing the design.
