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

Changelog:

• major overhaul of the in-game hook code, with more help from the FPGA, to significantly reduce CPU footprint. This improves hook compatibility with a variety of games.
• in-game hook: avoid disruption of manual controller reads (fixes controls in Super Star Wars games)
• new option: “Hide file extensions” (effective after next directory change)
• do not silently fail to load saved games when the sd2snes/saves folder does not exist (create the folder instead)
• do not silently fail to load/save cheat files when the sd2snes/cheats folder does not exist (create the folder instead)
• Cx4 core now runs at exactly 20Mhz
• fixes:
  • MSU1: avoid missed control register status changes on rapid rewrites (fixes FF3 Dancing Mad, Zelda FMV missing audio)
  • fix auto region patch timing (hopefully)
  • fix DSP1 header detection (fixes Ballz 3D JPN)
  • add reset hook to boot games on start of frame only (fixes Boogerman PAL)
  • clear entire SPC700 RAM (do not spare IPL area) – fixes echo artifacts in many games
• minor cosmetic changes:
  • resize SPC player loading window
  • prevent flickering letters on System Information screen
