psx-mc

Use psx-mc for PS1 memory-card files and host-side save tests. Start on a RAM-backed card while developing your save format.

How the crate is organized

Block abstracts 128-byte card frames. HardwareCard talks over SIO0 when hw is enabled; RamCard supplies a host-test backing store. Card adds the PS1 filesystem and save container. Internal fs and ram files implement those layers; compress optionally provides LZSS compression.

Integration notes

Use default-features = false for logic tests that do not need hardware transport. Treat formatting as a destructive operation that requires an explicit user action; do not copy an automatic-format snippet into a game's startup path. Check errors, free space and existing filenames before writing. Controller and card access share SIO0 and need coordinated ownership.

The complete memory-card diagnostic starts with a read/hash pass and enables a guarded test write only through its button combination. Read its preflight checks before adapting it.
