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.

Changelog:

v1.16 – 29/11/2021

Updated:

• Illegal/undocumented opcodes to the CPU Emulator:
  • LAE (LAS/LAR) Combinations of STA/TXS and LDA/TSX.
  • ANE (XAA) Combination of an immediate and an implied command.
  • All 6502/6510 instructions have been implemented.
• Increased the maximum number of files per directory from 512 max to 800 max.
• Improved delay routine for read/write eeprom via I2c bitbang, it should now be compatible with all levels of the XC32 compiler code optimization.
• Replaced and splitted the Splash Screen Logo during the boot. Thanks to Federico di dato for the Retrobit LAB logo.

Fixed:

• The BRK opcode, opcode that will probably will never used in our case.
• Missing +2 Machine Cycle Times for the opcodes: BPL,BMI,BVC,BVS,BCC,BCS,BNE,BEQ due to some previous performance improvment of the 6502/6510  emulator code, i was probably drunk, indeed, i’m sure. %-)
• The clock “|CIA|” was displayed mistakenly when you choose to play a file in DMP format but this is wrong because the DMP file format doesn’t support the information of clock used (VBI/CIA) in the file header.
• The previous and next button did not work if there are only two files (SID or DMP) available to play in the folder.
• Incorrect Machine Cycle Times for the NOP opcode, four times instead of two. %-)
• Sometimes the version number displayed during boot would pop outside from the right side of the oled screen.
• Wrong Machine Cycle Times for the SLO, SRE(LSE), DCP, RLA, ISC(ISB) Illegal/undocumented opcodes with Indexed-indirect addressing of X,Y-Registers.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Sorry for the delay, but it just escaped me to post it here.

Features added:

• [All] USB (usb2snes) support by RedGuy
• [All] save state support (via USB/savestate2snes) by RedGuy
• [All] stand-alone save state features by FURiOUS
• [All] some compatibility improvements and optimizations for stand-alone save states by ikari_01
  • Add support for YAML list items for multiple savestate_fixes entries per game
  • Add support for simple bitwise operations on savestate_fixes patches
  • Add support for verbatim code execution on savestate_fixes patches – notably fixes Star Ocean (decompressed) save states (however the save state hook still needs CPU time optimization to prevent music glitches in Star Ocean.)
  • Add IRQ support on top of NMI for the save state hook – this enables save states on Out Of This World and possibly other games that only use IRQ. Also fixes controller input capture on a number of games so the game-specific input hacks could be eliminated.
  • Moved save state code outside of the USB hook area to make room for USB hook execution.
• [All] SGB support by Redacted173.
• [All] favorite games list by freelancer42

Fixes:

• [All] Fixed data caching bug in MSU1 data extension which could cause wrong data to be streamed
• [All] Savestates: do not try to capture data that is already in cartridge space anyway (e.g. SRAM). Fixes text distortion in Near’s Bahamut Lagoon translation when loading a state.
• [All] Fixed YAML config parser to support comment signs after list start items
• [All] Fixed SNES open-bus contamination (fixes sprite flickering in Near’s Bahamut Lagoon translation, certain speed runs that rely on open bus behaviour)
• [All] (hopefully) fixed rapid data line toggling sometimes resulting in address line glitches, causing random crashes in extreme cases, and occasional garbled graphics on SMRPG among others
• [All] Fixed data integrity problems when loading BSX games

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:

v1.15 – 26/9/2021

Updated:

• Slightly improved the CIA timing, now the SID tune “https://hvsc.csdb.dk/MUSICIANS/P/Page_Jason/25_Hurts.sid” and probably some others they sounds fairly well without “clicking/noise/beeping” in some parts of the song. *
• Slightly improved the VBI timing, now the SID tune “https://hvsc.csdb.dk/MUSICIANS/S/Stinsen/Freeloader.sid” and probably some others they sounds fairly well without  “clicking/noise/beeping” in some parts of the song. *
• When the (Auto/Random/Intro) MODE is used the brightness of the oled is restored on each change of music until the default timeout is reached.

* I’ll never stop saying we are far away from my personal feeling of absolute perfection but sound ok for 90% of peoples, luckily there aren’t many SID sound purists :-D
Many people still think that a SID played with a SID emulator on a Mobile Phone or PC sounds absolutely identical to the one played with the SID in the original hardware version :-|

Fixed:

• In some cases the choice of subtunes is no longer displayed if the SID supports the multi-tunes after the implementation of clock speed emulation display.
• Fixed subroutine which takes care of loading and initializing the SID tune with SUBTUNES, were are missing some variables such as the “show_sidinfo_model” and some debug strings.
• LAX Opcode $AB instead of LXA (https://www.oric.org/ftp/ceo/ceomag/downloads/ebooks/nomoresecretsnmos6510.pdf) Used by this SID Tune: https://hvsc.csdb.dk/MUSICIANS/H/Holt_Hein/Whats_Your_Lame_Excuse.sid

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.

This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.

The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick

The HXC Usb (Gotek) firmware supports: + many more….

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:

v1.14 – 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.

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

Changelog:

v1.13 – 3/8/2021

Added:

• Illegal/undocumented opcodes to the CPU Emulator:
  • RLA (Combination of two operations with the same addressing mode (Sub-instructions: ROL, AND))
• From an idea of Faber Pixel we have also added other information of the SID file on the small OLED screen (information available in the header of the file).
  • With a frequency approximately of 7 seconds, the Load Range, Init Address and Play Address in hex addresses will be displayed on the screen alternating with the information of the SID Name, Author and Copyright.

Sample:

• Range: $1000-$2275
• Init Address: $1000
• Play Address: $1003

Obviously the displayed address range is the real memory occupation.

Fixed:

• The visualization of the SID Model of the tune that is playing every 5 seconds alternated between the playback mode icon. (Thanks Gianluca Renzi)
• Missing the file error handling in the subSong subroutine.

v1.12 – 18/07/2021

Updated:

• Improved a little bit the file error handling.
  • If you try to load a SID Stereo file a message “Stereo SID detected, but cannot play it!” will be displayed on the OLED screen.
• Modified the modality of visualization of the SID Model of the tune that is playing.
  • Now the display of the SID Model is alternated between the playback mode icon approximately every 5 seconds.

Added:

• Message during the boot that warns a checking of the USB storage and the correct filesystem mounting of the USB pen drive.
• Added six duplicate and probably useless opCodes, we are speaking about the “NOP” (they are $1A, $3A, $5A, $7A, $DA and $FA)
• Added one opcode absolutely useless for our use, we are speaking about the  “JAM”.

Fixed:

• Fixed some opCodes Addressing mode (Accumulator Addressing instead of Immediate Addressing)
