I got frustrated with wanting to play some SNES games and finding out that my Super Everdrive could not play them due to the needed enhancement chips. Commence ordering the SD2SNES from StoneAgeGamer.

Features list taken from StoneAgeGamer

Features
  • 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)
    • BS-X memory map / Satellaview base unit registers (clock)
    • DSP1 / 1b
    • DSP2
    • DSP3
    • DSP4
    • ST-010
    • Cx4
    • MSU1 (Each supported enhancement chip can be used in conjunction with MSU1.)
    • S-RTC
  • 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
