Keeping SC64 firmware up to date is highly recommended. `sc64.py` script is tightly coupled with specific firmware versions and will error out when it detects unsupported firmware version.
SC64 holds some configuration after script has exit. To reset it simply run: `python3 sc64.py --reset-state`. Internal flashcart state can be checked by running: `python3 sc64.py --print-state`

## Uploading game/save
`python3 sc64.py --boot rom --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. Check included help in script to check available save types.
64DD games require DDIPL ROM and disk images. To run disk game type `python3 sc64.py --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.
If booting game through included bootloader isn't a desired option then flashcart can be put in special mode that omits this step.
Run `python3 sc64.py --boot direct-rom --rom path_to_rom.n64` to disable bootloader during boot and console reset. By default `sc64.py` script will try to guess CIC seed and calculate checksum. To change seed or disable CIC use `--cic-params 0x3F,0` argument with appropriate values. Refer to included help in script for values meaning. This option is useful only for very specific cases (e.g. testing custom IPL3 or running SC64 on top of GameShark).
