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)
DSP1 / 1b
DSP2
DSP3
DSP4
ST-010
Cx4
MSU1
S-RTC
Work in progress
GSU-1/2 (SuperFX)
To Do:
Action Replay/Game Genie code support
SPC7110 – with the Far East of Eden Zero translation patch in the works it would be a shame not to support it.
S-DD1
??? (you name it)
To be determined:
SA1
Unlikely:
ST-011
requires 54kB of Block RAM; the FPGA only provides 36kB of Block RAM.
ST-018
yet unknown architecture but probably more powerful than the ST-011.
OBC-1
Simple bit-manipulating chip as OAM accelerator for one game. Implementation is almost a no-brainer but I’m not interested right now. 作者: roto 时间: 2012-9-9 10:48
