CoreDocSNES
- Cycle accurate SNES replica.
- Supports LoROM, HiROM, ExHiROM.
- Supports additional chip: DSP-1/2/4
- Save/Load Backup RAM.
- Video support: VGA, RGB, YPbPr.
- Core binaries (Install .rbf file to SD card)
- Original source code
Copy the *.rbf
file at the root of the SD card.
You can rename the file to core.rbf if you want the MIST to load it automatically at startup.
Roms can be copied anywhere on the SD card and are selected via the OSD menu. They should be .SFC or .BIN ROM format. SMC ROMS will need to be converted to .SFC (easily done online). SMC only difference compared to SFC is that they have a 512byte header, the conversion tools will remove this. If there is no header on the SMC ROM you can simply rename it to SFC.
If a ROM doesn't work it's possible it uses one of the unsupported enhancement chips. Currently only DSP is supported (the most common chip).
The core will start with a blank screen. Press F12 to enter the OSD menu or SELECT+START on the gamepad.
Make sure you select the correct LoROM/HiROM setting before loading the ROM!. You need to use a SNES ROM utility to discover the ROM type, the Core currently cannot automatically detect the ROM type. If you have many files you might want to store them into alphabetized sub-folders to access them more quickly.
Controls:
- Use one or two gamepads
- Buttons 3 and 4 map to Select and Start.
- F12 to open OSD
- Configure additional buttons using mist.ini joystick_remap. Example setting for iBuffalo SNES gamepad:
joystick_remap=0583,2060,1,2,4,8,10,20,100,200,400,800,40,80
MIST front panel buttons:
- (left) Reset MIST to default core
- (middle) Open OSD menu, hold to switch between VGA & RGB.
- (right) Reset SNES with current ROM
Many games allow save game states or highscores to an on-cart battery backed SRAM chip. This core supports backup and load of this SRAM to the SD card:
- Create an empty file of size 64K (65536 bytes) on the SD-Card with .sav extension. It doesn't matter if this file is larger than the SRAM backup size, just as long as it is not smaller.
- It is important you select the correct LoROM or HiROM in the OSD for the chose ROM as the incorrect setting can cause the SRAM backup/load to fail without notification. Some games will appear to load correctly even with the wrong LoROM/HiROM setting.
- After loading the game ROM, choose "Mount SAV" from the OSD, and select the previously created file. The yellow LED will lit, indicating that the backup file is loaded.
- Before you load a new ROM, or turn off the MIST, don't forget to write back the contents of the backup RAM to the SD-Card via the "Write Save RAM" OSD option. You can only write back the SRAM contents when the yellow led lit!

Generate .SAV files for all ROMS in a directory:
for FILE in *.sfc; do dd if=/dev/zero of="${FILE/%.sfc}.sav" bs=1 count=64k; done
