Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Sorry for the delay, but it just escaped me to post it here.

Features added:

• [All] USB (usb2snes) support by RedGuy
• [All] save state support (via USB/savestate2snes) by RedGuy
• [All] stand-alone save state features by FURiOUS
• [All] some compatibility improvements and optimizations for stand-alone save states by ikari_01
  • Add support for YAML list items for multiple savestate_fixes entries per game
  • Add support for simple bitwise operations on savestate_fixes patches
  • Add support for verbatim code execution on savestate_fixes patches – notably fixes Star Ocean (decompressed) save states (however the save state hook still needs CPU time optimization to prevent music glitches in Star Ocean.)
  • Add IRQ support on top of NMI for the save state hook – this enables save states on Out Of This World and possibly other games that only use IRQ. Also fixes controller input capture on a number of games so the game-specific input hacks could be eliminated.
  • Moved save state code outside of the USB hook area to make room for USB hook execution.
• [All] SGB support by Redacted173.
• [All] favorite games list by freelancer42

Fixes:

• [All] Fixed data caching bug in MSU1 data extension which could cause wrong data to be streamed
• [All] Savestates: do not try to capture data that is already in cartridge space anyway (e.g. SRAM). Fixes text distortion in Near’s Bahamut Lagoon translation when loading a state.
• [All] Fixed YAML config parser to support comment signs after list start items
• [All] Fixed SNES open-bus contamination (fixes sprite flickering in Near’s Bahamut Lagoon translation, certain speed runs that rely on open bus behaviour)
• [All] (hopefully) fixed rapid data line toggling sometimes resulting in address line glitches, causing random crashes in extreme cases, and occasional garbled graphics on SMRPG among others
• [All] Fixed data integrity problems when loading BSX games
