Crate psx_settings 

Shared, allocator-free game preferences.

The record intentionally contains only settings that recur across PSoXide games. Games remain free to keep simulation or renderer-specific options in their own save data. The byte format is explicit and checksummed so a newer executable can reject a torn or incompatible card write and fall back to its shipped defaults.

MAX_RECORD_LEN

Current record format version.

Functions

format_and_save

Format the card if it has no MC header, then save the profile. Call this only after the player agreed to format: it replaces the directory of an unformatted card, and every save the card held stops being listed. A formatted card is left alone and the profile is saved onto it.

format_and_save_to_slot_one

format_and_save on the controller-1 memory-card slot. This is the call that can erase a card’s directory; reach it only from an explicit “format this card?” answer.

load

Load one exact profile shape from a standard PS1 memory-card file.

load_from_slot_one

Load a profile from the controller-1 memory-card slot, driving the port through port.

load_slot_oneDeprecated

load_from_slot_one on a token the caller does not hold.

save

Save one profile into a standard PS1 memory-card file.

save_slot_oneDeprecated

save_to_slot_one on a token the caller does not hold.

save_to_slot_one

Save a profile to the controller-1 memory-card slot, driving the port through port. Existing files with the same name are replaced. A card that is not formatted is refused with CardError::Card(psx_mc::Error::NotFormatted) and not touched; use format_and_save_to_slot_one once the player has agreed to format.
