SUPER ZSNES - A GPU-powered SNES emulator rewritten from scratch with hi-res Mode 7, per-game enhancements, and a modernized classic UI.
What's new in v0.230:

• Optimized GPU memory allocations & texture upload routines
• Initial SuperFX emulation (note: Not enhanced yet, still some work to be done)
• Fixed windowing off by 1 line issues
• Fixes to dual window shader logic
• Fixes to BG latch routines
• Forced blank fixed color issues fixed
• Added separate volume control for MSU1 audio
• Added CRC check for DSP1 rom, improved message for persistent data folder location
• Added disable '.szsnes' folder saves checkbox
• Fixed audio glitch when loading new game
• SRAM and main menu settings now saved more frequently
• Optimized enhancement data loading speed
• Added HEX editing of GUI colors, multiple default settings (Default, Classic ZSNES, Red)

Note: The PC version may trigger a false trojan warning in certain virus scanners. It's pretty common as emulators have a certain pattern in them that scanners find similar to how trojans sometimes work.
