Here you can download the latest firmware releases and tools for the FPGASID.

FPGA binaries:

latest version:
FPGASID FPGA revision 09 (improved audio quality, adjustable 6581 filter curve, C128 mode, bugfixes)
CAUTION: For Alphatest hardware do NOT update the CPLD with the USB-Blaster! See release notes.

older versions:
FPGASID FPGA revision 08 (fix loading of configuration on power up, some ConfiGuru improvements)
FPGASID FPGA revision 07 (fixing 8580 distortion issues, some ConfiGuru improvements)
FPGASID_proto1 FPGA revision 06 (Christmas Release 2017 including the new exciting ConfiGuru tool)
FPGASID_proto1 FPGA revision 05 (bugfixes H.E.R.O. and Katakis)
FPGASID_proto1 FPGA revision 04 (keep configuration across hard-reset)
FPGASID_proto1 FPGA revision 03 (fixing a 6502 Bus timing problem)
FPGASID_proto1 FPGA revision 02 (bugfixes after first test results)
FPGASID_proto1 FPGA revision 01 (first version used in Alpha Test)

Support Software:
The release packages from revision 6 onwards include a Configuration and flashing tool named 'ConfiGuru'. The tool will run directly on a C64.
When your FPGASID uses a firmware below revision 06 you will need a USB-Blaster and this flashing tool to program the FPGASID with the latest firmware (with instructions). First read the instructions in the dropbox folder, then download the correct setup file.

Documentation:
This ZIP-Archive contains a register description and some sample Programs for the FPGASID configuration.
FPGASID_docs_and_progs_small_170518.zip. These files are somehow outdated because the firmware archives from revision 06 onwards contain a powerful configuration tool for the C64 that allowing you to configure FPGASID to your needs without knowing all the details. Programmers please stand by for a new documentation package to be uploaded here in the near future. This documentation will then reflect all changes from revision 6 onwards.
