The return of the Hybrid Sid Player by xAD/Nightfall

Based on the Project and Hardware Schematic by Markus Gritsch released in the years 2011-2015 on the forum dangerousprototypes. Thanks Markus.

Changelog:

v2.10 – 16/6/2025

Added:

• Added the info of the video mode on the OLED (PAL – NTSC – Both – Unk), the info is alternated with the VB: CIA or VBI.

Updated:

• Improved the verification of the Socket number for the FPGASid in the configuration file and error reporting on the display if it is incorrect.
  •     FPGASid Socket Error
  •     Check the config.in
  •     FPGASid Disabled

• The default SID Socket (DEFAULT_SID_SOCKET) in case the Auto Switching mode is used will always be the Socket where the FPGASid has been installed.

Fixed:

• Playing the song “Acrouzet_-_Your_Indecision.sid” i found a bug, the Player did not choose the right Timing for NTSC and consequently the playback of the song was too slow. The problem was that this song uses VBI with NTSC timing, usually you can find CIA songs with NTSC timing. It was a bug in the player that it couldn’t get the correct information from the SID header.

.- the inexpensive dual-SID/FM replacement that you can build yourself -.

SIDKick pico by Frenetic is a microcontroller-based C64 SID replacement. Analog inputs for paddles and mice are available just as for the original SID.

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.

Please read the troubleshooting section in case you experience problems.

A new firmware update for the ARMSiD has been released by Nobomi.

News features and fixes in FW 2.16:

• Fix for 2 MHz mode C128. Since this firmware ARMSID is functional for all modes and types of communication with C128 (even those incompatible with SID documentation).
• Added to the configuration the possibility to use the EXT IN input (pin 26) as an analog input and connect it to the internal mixer, as on the original chip. You should expect a slight increase in noise background from this input, I recommend using it only when you really need this feature.
• Also added to the configuration the possibility to change the emulation detection threshold of the 6581/8580 according to the input voltage (pin 28), so called autodetection. Originally this limit is set to 10.5V, what is below indicates 8580 emulation, what is above so 6581. With the new setting, this limit can be about 2V, so you can use logic levels of 5V or even just 3V for switching the emulation type (pin 28 is not used for power supply in ARMSID, only for voltage measurement, no power supply on this pin is required for function).

A new version of the firmware for the Ultimate U2+L by Gideon is released.

Changes in 3.11a:

• WiFi support – Now that the WiFi modules for the U2+L are available, you will need this firmware to enable it. In this zip there are two files; the firmware update for the cartridge itself (.u2l) file and the firmware file for the ESP WiFi module (.esp). They have to be applied in this order.
• Ethernet fix – Improves compatibility with some switches and routers. The LAN should now work with these.
• Garbled characters fix. – On some machines, especially on NTSC machines, the 3.11 firmware gave some timing issues. This build should fix that.
• Ulticopy fix – In 3.11 Ulticopy was broken; it should work again – supposedly – not tested.

Due to “life” (e.g. house renovation) there has not been any time for testing this firmware for other hardware platforms. Will come soon.
