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:

v1.11 – 22/06/2021

Updated:

• Decreased more than before the brightness of the display after 10 seconds if no activity is done on the buttons or encoder.
• Slighty improved the timing (CPU cycle) of the 6510 emulator but we are far from my perception of absolute perfection :-D

Added:

• Illegal/undocumented opcodes to the CPU Emulator:
  • RRA (Combination of two operations with the same addressing mode (Sub-instructions: ADC, ROR))
• Automatic hardware SID switch between ZIF Socket #1 and ZIF Socket #2 (example if it is made only for 6581 or 8580).
  • This features is included in the prototype pcb. The swap will be displayed by a led placed on the lower part of the ZIF Socket.
• Improved a little bit the file error handling.
  • If you try to load a file not supported a message “Wrong file format” will be displayed on the screen.
  • If you try to load a RSID file format a message “RSID detected, but cannot play it!” will be displayed on the screen.
