The return of the Hybrid Sid Player by xAD/Nightfall & Gianluca Renzi (RetroBit Lab)

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

Changelog:

v1.17 – 31/12/2021

Added:

• Change visualization status of the LED for Socket #1 and Socket #2 available on the Olimex Development Board and the SID Player PCB.
• A configuration file (config.ini) for some important settings of the SID Player. The file will be loaded during the boot and must be present in the ROOT of the filesystem of the USB key.If the file is not found, the player will configure itself with the default values. Thanks to Gianluca Renzi (RetroBit Lab) for his lite INI file parser.

Below is an excerpt from the “config.ini” file.

# Select the Sid model for the Tune played by the SID Player on the Socket #1 or Socket #2.
# Specify the socket which you want to play the sid tunes (example for SID_8580_SOCKET write
# the number 2 if you want it to be played with the SID 8580 installed on socket #2)
# This configuration makes the use very dynamic for everyone. – default: socket #1,#1,#2,#2
TUNE_UNKNOWN_SOCKET=1
TUNE_6581_SOCKET=1
TUNE_8580_SOCKET=2
TUNE_BOTH_SOCKET=2
# Use Armsid with Auto Switching (0:Disabled – 1:Socket #1 – 2:Socket #2) – default: 0
# Note: When you use the auto detection and switching of the SID model with the ARMSID this can be
# used only in one of the two sockets, the other socket is completely ignored and can remain empty.
ARMSID_SOCKET=0
# Brightness of the OLED. (0 … 255) – default: 127
OLED_BRIGHTNESS=127
# Brightness of the OLED in IDLE mode. (0 … 255) – default: 10
OLED_BRIGHTNESS_IDLE=10
# Enable the serial DEBUG. (1 Enable | 0 Disabled) – default: 0
SERIAL_DEBUG=0

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

News features and fixes in FW 2.13:

• Further optimization of code speed and size. Also bus operations are faster, finally “paddles” are successfully read on NTSC machines even with the oldest HW versions of ARMSID (with components on top) !
• ARMSID start is also faster. Instead of hundreds of milliseconds, ARMSID is fully functional in less than 15 milliseconds after power-up !
• Added the possibility to “fix” the so-called ADSR bug, i.e. a bug in the envelope generator, which is inherent to the original chips and is reproduced in ARMSID too. This is not needed in the C64 for compatibility reasons, but if you use ARMSID in synthesizers, you might be interested in this feature.
• Slightly modified quality (Q) of filter circuits for even more faithful reproduction of MOS8580.
