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:

v1.18 – 28/1/2022

Fixed:

• When you are in Manual mode of playing SID the timeout timer wrongly are also increased into a variable but this timer works only for the modes: auto/random/intro.
• Wrong STATIC variable for the debug via serial. the serial debug don’t works correctly in some part of the code. %-)
• Wrong variable for the Timeout check if the time is longer then 99 seconds. %-)

Updated:

• Freed and remapped to another destination the MCU pins of PAUSE and FFWD buttons to use them with the CS for the SID #2 and R/W because we needed 2 MCU pins 5v tolerant and there aren’t many left :/
• Described some parts of the source code.
• Added new parameters to the configuration file (config.ini).
  • Playback timeout in seconds of the .SID files for AUTO/RANDOM and INTRO modes.
  • Configure the best baudrate for the debug via Serial.
  • Disable or Enable the visualization of the VU-METER for the 3 sid voices.

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

# Serial Debug Baudrate – default: 115200
SERIAL_BAUDRATE=115200
# Set the Timeout in Seconds for the AUTO/RANDOM playing mode – default: 2 minutes
AUTORND_TIMEOUT=120
# Set the Timeout in Seconds for the INTRO playing mode – default: 15 seconds
INTRO_TIMEOUT=15
# Write 0 if you want to disable the visualization of the vu-meter for the 3 x sid voices.
# Default: 1
SID_VUMETER=1

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

Changelog:

v1.14 – 22/8/2021

Added:

• Illegal/undocumented opcodes to the CPU Emulator:
  • ISC (Combination of two operations with the same addressing mode: INC, followed by SBC)
• Display emulation clock:
  • I used the same position of the OLED display where the sid Subtunes are displayed (if are present), otherwise if the song doesn’t support subtunes it will displayed in the same position the type of clock speed emulation: |CIA| or |VBI|.

Fixed:

• DMP files additional information:
  • Display of additional information of the SID when a DMP files is played but there are no additional information to display in the header of the DMP files.
• CPU timing:
  • Some months ago when i wanted to fix the timing of the 6510 CPU emulator i made an unforgivable huge mistake :-D
• Random Playing Mode:
  • The load routine try to load a index of a file that don’t exist and everything freeze.
• File error handling:
  • When an load error occurs and you are in the TUNEINFO mode the player don’t back to the FILE Browsing mode.
