SD2SNES

• SD/SDHC/SDXC support (tested up to 64GB; no exFAT support so SDXC cards must be reformatted using FAT32)
• High quality push-push memory card slot
• Fast ROM loading (~9MB/s)
• Fast menu navigation
• Directories are sorted automatically, no need for FAT sorting tools
• High resolution menu (512×224) for adequate display of long file names
• Real Time Clock
• Supports ROM size up to 128MBit (96Mbit actually implemented)
• Automatic near-time SRAM saving to SD Card (while the game runs). Some limitations apply:
• near-time saving is switched to periodic saving when a game is found to use the SRAM as work RAM.
• Automatic saving is disabled when MSU1 is used. SRAM is saved on reset.
• Enhancement chip support (see below for implementation status)
• SuperCIC key (SNES CIC clone):
• enables operation on unmodified consoles of all regions
• supports software 50/60Hz switching on SuperCIC enhanced consoles only (to be performed by sd2snes firmware, not yet implemented there)
• Auto region patching: eliminates “This Game Pak is not designed…” messages regardless of 50/60Hz setting
