Commodore 64
C64_260721.rbf
- SID Audio Chip Replacement
Replaced the old dual-SID implementation (VHDL 6581 + Verilog sid8580) with the MiSTer reDIP-SID engine released several weeks ago (full Verilog)
- Digifix bug correction (was previously wrongly active for 8580 and not for 6581 when it should have been reverse way)
- Audio filter fix
When off, all voices bypass the SVF through the direct path which is supposedly the correct hardware behaviour.
I also decoupled digifix from the filter toggle (independant features now)
- Colour palette
Replaced fpga64_rgbcolor.vhd with the MiSTer version allowing palette selection. Added the necessary port through fpga64_sid_iec entity to c64colors instantiation as well as OSD menu entry in the "audio/video" section to allow palette selection.
Available choices are : Colodore, Ultimate, Pepto-PAL, Vice, Vice6569R1, Vice6569R5, Vice8565R2 and Lemon64.
Default palette is now Colodore as on MiSTer (was Pepto-PAL on the old MiST core)
