First time setup

Windows platform: replace ./sc64 in examples below with sc64.exe

1. Download the latest sc64-{os}-{version}.{ext} (choose OS matching your system) and sc64-firmware-{version}.bin from GitHub releases page
2. Extract sc64-{os}-{version}.{ext} package contents to a folder and place sc64-firmware-{version}.bin inside it
3. Update SC64 firmware to the latest version with ./sc64 --update-firmware sc64-firmware-{version}.bin
4. Run ./sc64 --print-state to check if update process finished successfully and SC64 is detected correctly

---

Firmware backup/update

Keeping SC64 firmware up to date is highly recommended. sc64 executable is tightly coupled with specific firmware versions and will error out when it detects unsupported firmware version.

To download and backup current version of SC64 firmware run ./sc64 --backup-firmware sc64-firmware-backup.bin

To update SC64 firmware run ./sc64 --update-firmware sc64-firmware-{version}.bin

---

Internal flashcart state

SC64 holds some internal configuration options after sc64 executable finished running. To reset it simply run: ./sc64 --reset-state. Internal flashcart state can be checked by running: ./sc64 --print-state

---

Uploading game/save

./sc64 --boot rom path_to_rom.n64 --save-type eeprom-4k --save path_to_save.sav

Replace path_to_rom.n64 / eeprom-4k / path_to_save.sav with appropriate values for desired game. Script will try to autodetect used save type so explicitly setting save type usually isn't needed. Check included help in program to list available save types. Arguments --save-type and/or --save can be omitted if game doesn't require any save or you want to start fresh.

---

Downloading save

./sc64 --backup-save path_to_save.sav

Replace path_to_save.sav with appropriate value. Specifying save type isn't required when set correctly previously.

---

Running 64DD games

64DD games require DDIPL ROM and disk images. To run disk game type ./sc64 --boot ddipl --ddipl path_to_ddipl.n64 --disk path_to_disk_1.ndd --disk path_to_disk_2.ndd.

Replace path_to_ddipl.n64 / path_to_disk_x.ndd with appropriate values. Argument --disk can be specified multiple times. Only .ndd disk format is supported currently. To change inserted disk press button on the back of SC64 flashcart. Make sure retail and development disks aren't mixed together. 64DD IPL can handle only one drive type at a time.

---

Direct boot option

If booting game through included bootloader isn't a desired option then flashcart can be put in special mode that omits this step. Run ./sc64 --boot direct-rom path_to_rom.n64 to disable bootloader during boot and console reset. This option is useful only for very specific cases (e.g. testing custom IPL3 or running SC64 on top of GameShark).

---

Debug terminal

sc64 executable supports UNFLoader protocol and has same functionality implemented as aforementioned program. Use argument --debug to activate it.

---

LED blink patters

LED on SC64 board can blink in certain situations. Most of them during normal use are related to SD card access. Here's list of blink patters meaning:

Pattern	Meaning
Nx [Short ON - Short OFF]	SD card is being accessed (initialization or data read/write) or save writeback is in progress
Nx [Medium ON - Long OFF]	CIC region didn't match, please power off console and power on again
2x [Very short ON - Short OFF]	Pattern used during firmware update process, it means that specific part of firmware has started programming
10x [Very short ON - Very short OFF]	Firmware has been successfully updated
30x [Long ON - Long OFF]	There was serious problem during firmware update, device is most likely bricked

Nx means that blink count is varied.

LED blinking on SD card access can be disabled through sc64 executable. Please refer to included help for option to change the LED behavior.
