This release contains the firmware for SIDKick pico.

Note: there are (many!) different .uf2-files are firmware files for normal C64/C128 vs. Ultimate64/Commodore 64 Ultimate, AND for the different SKpico variants (PWM and/or DAC output, flashing (RGB-)LED on/off AND for hardware revision 0.1 and 0.2, as well as for the SKpico2040DAC and the SKpico2350DAC/PWM).

The paddle offsetting has been accidentally deactivated in version 0.223, this is now fixed in version 0.224.

Of course it includes all features introduced with the 0.22-series releases:

• a special addressing mode for Ultimate64/Commodore 64 Ultimate which requires a single setup only to play dual-SID or SID+FM
• advanced SID filter settings plus 19x measured 6581 filter curves (measurements by Antti S. Lankila)
• support for Pico 2 / RP2350
• change bus timings (if still necessary at all!) by pressing reset for ~5 seconds, factory reset by pressing reset for >10 seconds
• optional offsetting of paddle values now via the configuration tool

(I cannot test all 66 firmware variants, let me know if one isn't working as expected)

The 0.223 version...

• introduces a special addressing mode for Ultimate64/Commodore 64 Ultimate which requires a single setup only to play dual-SID or SID+FM
• fixes a bug in the combined waveform emulation

Of course it includes all features introduced with the 0.22-series releases:

• advanced SID filter settings plus 19x measured 6581 filter curves (measurements by Antti S. Lankila)

This release contains the firmware for SIDKick pico.

Note: there are different .uf2-files are firmware files with PWM and/or DAC output, flashing (RGB-)LED on/off AND for hardware revision 0.1 and 0.2, as well as for the SKpico2040DAC and the upcoming SKpico2350.

The 0.22 version includes new features such as:

• advanced SID filter settings plus 19x measured 6581 filter curves (measurements by Antti S. Lankila)
• support for Pico 2 / RP2350
• change bus timings (if still necessary at all!) by pressing reset for ~5 seconds, factory reset by pressing reset for >10 seconds
• optional offsetting of paddle values now via the configuration tool

(I also added a version of the firmwares where the reset-functionality requires ~30 seconds and ~60 seconds reset press, in case the shorter times conflict with kernal switchers or other extensions)

Update on Jan 1st: included the correct SKpicopatch!

This release contains the firmware for SIDKick pico with only minor changes:
the reset behavior has been modified to avoid the problems reported for old ultimax cartridges (e.g. Jupiter Lander).

Note: there are different .uf2-files are firmware files with PWM and/or DAC output, flashing (RGB-)LED on/off AND for hardware revision 0.1 and 0.2, and the new SIDKick pico2040DAC.

This version includes the same features that have been introduced with the 0.21 step:

• flashing PRGs from disk drive 8 (<200 blocks)
• timing diagnostics and adjustment
• removing of audio bumps/ramps in PWM output (please report if this got worse with 0.211)
• optional offsetting of paddle values (in case diagnostic ROMs complain)

Please read the troubleshooting section in case you experience problems.

This release contains the fix for the NTSC-specific bug of firmware version 0.20 (and the fix for the bug I introduced with 0.201 :-)).

The 0.20x versions include some new features such as:

• FM emulation
• built-in PRG launcher

... and also some bugfixes, better stability (e.g. paddle/mouse handling). Please read the troubleshooting section in case you experience problems.

Note: I might have compiled a NTSC-specific bug into this release -- will be fixed in a couple of days. In case you experience problems (and have hardware revision 0.1) use firmware 0.14 until then.

Version 0.14 fixes some problems that sneaked into 0.13.

Updates for version 0.12 and 0.13:

• fixed bus value ttl
• more accurate timing of SID-commands
• flashing RGB-LED (WS2812) on GPIO 23 (installed on some Pico-clones, make sure the solder jumper for the RGB-LED is closed)

This release will be replaced soon, please wait for an update!
