Nobomi already developer of the famous ARMSID and ARM2SID, an excellent alternative developed with STM32 of the famous Commodore 64 Sound Chip, has made a nice interface via Terminal (putty) to update and modify the ARMSID configurations without using the native program that runs on the Commodore 64.

The project is based on Arduino UNO REV3, therefore very cheap, the sources are available on GITHUB and can be purchased HERE in the KIT version.

Nobomi has also ventured a SIDPLAYER that runs under Windows and via serial sends DATA and ADDRESSES which are captured by the ARDUINO and then send to the ARMSID and consequently plays the music but don’t expect a perfect SIDPLAYER,  it works but not perfectly.

However, i did not self-build it for this reason but to modify the ARMSID configurations without using the Commodore 64, this will come in handy to check for any problems when i implement the real time switch in the SID Player “The Return of the Hybrid SID Player” between 8580 and 6581 with ARMSID or ARM2SID sound chip.

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.
