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:

v1.13 – 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.
