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

Here’s what’s new since preview 4:

• Configuration menu. All settings are now available through the menu. Changes take effect immediately after confirming a setting with the A button. It can use some polish but should work fine. Note that the Video Mode settings are only effective on SuperCIC modded consoles.
• SRM files (save files) are now stored in sd2snes/saves/<romname>.srm – existing save files will be moved upon save, there is no batch migration.

Game fixes:

• DMA de-initialization has been reintroduced and changed from $00 to $ff. This reflects a real SNES better and hopefully finally fixes sprite corruption with SGnG and SSF2, AND title screen glitches/crashes with Pocky&Rocky US.

MSU1 enhancements:

• MSU1 volume boost: In case MSU1 audio is too quiet you can now increase volume in several steps. Available via Configuration->Chip Options.
• Interpolation filter to reduce aliasing, resulting in cleaner sound.
• Fixed a bug where volume calculation introduced DC offset to the waveform output. This eliminates clicking or humming on volume changes/fades.
• Changed MSU1 audio playback rate to exactly 44100Hz to match bsnes/higan implementation. Sound that syncs on bsnes should now also sync properly on sd2snes.
• MSU1 resume feature implemented (Thanks to Michaël Larouche!)

Miscellaneous:

• Missing ROM files are automatically removed from the “Recent Games” list. (Thanks to borti4938!)
• Background text is now properly greyed out in the SPC player.
• Ultra16 awareness (mostly thanks to borti4938!):
  • Ultra16 serial number and autoboot setting is displayed in the System Information screen.
  • Exiting from the SPC player doesn’t crash the menu anymore on Ultra16 consoles.
  • Soft reset is prolonged a bit on Ultra16 consoles so you have the opportunity to release the controller buttons, not entering the Ultra16 menu by accident.
  • Auto region patching is disabled on Ultra16 consoles so it doesn’t interfere with the Ultra16’s own facilities.

Critical & Minor bugs:

• Firmware locked up when loading Zelda 3 after soft-reset. I am surprised that it actually worked so well with all other games.
• Auto Region Patch setting wasn’t saved properly.
• Satellaview custom time had a garbled default value (year 1035). The default has now been fixed. If you’d like to apply it you can delete your config.yml or just the “BSXTime” entry from it to load the new default.
