Mesen-S 0.2.0

This release greatly improves accuracy, compatibility and adds support for some of the enhancement chips. The vast majority of (supported) SNES games should play without any issues - if you find problems in a game (freezes, graphical bugs, etc.), please report them!

General

• Greatly improved timing/accuracy for everything: CPU, PPU, SPC, DMA, etc. Including:
  • Numerous PPU fixes - graphical issues have been fixed in several games.
  • Freezes in several games have been fixed by improving the SPC emulation accuracy.
• Support for games using the DSP-1/2/3/4 and ST010/ST011 enhancement chips. Note: A firmware is required for these - the emulator will ask for the firmware when loading a game that requires one.
• Libretro support
• Added a number of UI options (mute in background, etc.) and corrected a few UI problems.

Debugger

• SPC debugger window (along with breakpoints, watch, labels, etc.)
• Sprite viewer
• Lua scripting
• Improved usability and added new features to tile/tilemap viewers
• DMA channel filters for the event viewer
• Misc. debugger features (break options, disassembly options, etc.)
• Ability to log the SPC and DSP-n chips in the trace logger.
• CC65/CA65 source code and symbols integration
• Labels/comments in the disassembly view

Huge thanks to everybody who helped out by testing, reporting bugs or sharing information!
