Firmware v0.1.4 is out with these changes:

• SPC Player (contributed by necronomfive/blargg)
• System Information screen now shows CPU/PPU revision (contributed by necronomfive)
• Satellaview: basic data transmission packet support (makes some more games boot, thanks to LuigiBlood for assistance and sample data packets)
• Number of supported files increased to ~50000 per card / 16380 per directory
• Slight speedup of menu text rendering
• Reduce load time of menu
• Adjust Cx4 timing to be closer to the original (Mega Man now defeats the boss in attract mode in Mega Man X2; test this against some emulators for fun. ;))
• adapt ROM mirroring size to file size if header information is invalid (fixes Super Noah’s Ark 3D, possibly others)
• MSU1 interface changes suggested by byuu:
  • Data offset 0 and audio track 0 are automatically requested on reset. This causes the busy flags to become 0 shortly after reset/startup.
  • $2000 bit 3 is now “audio error”, becomes valid after “audio busy” -> 0; set when an error occurred while preparing playback of the requested audio track
• write LED stays on when SRAM content changes constantly
• Fixes:
  • fix empty save files on FAT16 / incorrect free cluster count on FAT32
  • correct directory sorting (force parent directory at top of list)
  • fix text corruption when entering a directory with a scrollable name
  • fix files/dirs count in system information
  • make ‘sd2snes’ directory hiding case-insensitive
  • improve DAC I²S timing
  • fix occasional palette corruption in menu
  • fix SD clock glitch on ROM loading (occasional glitches/crashes)
  • fix memory write timing on ROM loading (occasional glitches/crashes)
  • fix SPI timing (ROMs not loading; System Information not working)
  • properly synchronize SNES control signals (occasional glitches/crashes)
  • fix floating IRQ output (occasional glitches/slowdowns)
