– Rewritten mappers : All.
– Rewritten WRAM, VRAM, PRGROM, CHROM and Nametebles management.
– Rewritten FDS support.
. Furthermore, an option has been added to select the mode for write operations. Until now, all writes were stored on an external file (diff file) to preserve the integrity of the disk image, now it’s possible to choose to write them directly to the FDS/QD file (making it portable to other emulators as well).
. Changed the format of the diff file, now I use the IPS format (which can always be applied to the original image).
– Rewritten the format and management of save states.
WARNING save states of version 0.110 or earlier are no longer compatible.
– Rewritten the audio of the VRC7.
Implemented the project « A YM2413 emulator written in C » of okaxaki :

• Added support to Wayland.
• Added support for "Fullscreen in window" with Wayland (the only type of fullscreen supported for now).
• Added iNES/NES 2.0 header editor.
• Added support for "Family Basic Keyboard" and "Subor Keyboard".
  • It's possible to capture and release keyboard input with the shortcut "Scrollock" and open and
    close a virtual keyboard with "CTRL+X".
  • Implemented the "Paste" function. It's possible to paste the text by dragging it in the main
    window of the emulator or copying it and then press the right mouse button and selecting "Paste".
    The text will be inserted through the simulation of the pressure of the keys and it will always
    be possible to interrupt the insertion by pressing the ESC key. During the paste, the Fast Forwarding
    will be active to reduce the waiting time.
  • Added support for the tape data recorder. Added a "Tape" submenu in the "NES"...

The 2.6.6 release is mainly a maintenance update for the mappers and emulation core with a few new features added in.

Some of these new features apply only to the Qt/SDL version of the GUI.

Click to expand...

• Significant performance improvement / reduced CPU usage due to a rewrite of the 6502 CPU emulation code
• Fixed a PPU bug where the PPU would sometimes render the wrong backdrop color when rendering was left disabled at the start of a frame; this caused occasional top-of-screen flickering in Battletoads, which leaves rendering disabled for the first ~7 visible scanlines of every frame
• Fixed a bug that caused PAL audio sync to time to ~49.9 FPS instead of 50 FPS
• Added an option to have audio sync time to native NES speed (~60.1 FPS NTSC / ~50.007 FPS PAL) instead of aiming for exactly 60 FPS NTSC / 50 FPS PAL
  • Note this will cause severe audio skipping if combined with VSync on a display with 60Hz refresh rate
