Description:
1. The SD2Snes cartridge is a SD Card Cartridge for the Super Nintendo / Famicom / Snes.
2. Xilinx Spartan FPGA Firmware updates can be done without any special hardware
3. This cartridge already supports the Capcom CX4 microchip which is used in both the Megaman/Rockman X2 and Megaman/Rockman X3 cartridges. NTSC/U/J and PAL/E ROMs will run without a hitch as well as the Megaman X3 Zero Mission ROM
4. Works with ALL DSP chips including third party vendors (DSP1A/B, DSP2, DSP3, and DSP4). SD Gundam GX and TopGear 3000 run as well as Dungeon Master and Pilotwings.
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)
- 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
ENHANCEMENT CHIPS:
Each supported enhancement chip can be used in conjunction with MSU1.
IMPLEMENTED:
BS-X memory map / Satellaview base unit registers (clock)
