Add PowerSaves for 3DS device support — DS cartridge save backup#5
Conversation
PowerSaves for 3DS is a USB HID slot-1 adapter (VID 0x1C1A PID 0x03D5) made by Datel. Despite the 3DS branding, the device's generic NTR and SPI passthroughs work cleanly on DS cartridges, so this driver uses it purely as a save-backup tool for DS carts. What ships: - Driver (src/lib/drivers/powersave-3ds/) — speaks the 64-byte HID protocol, switches between ROM and SPI modes, identifies the cart via NTR chip-ID, validates the on-cart header (CRC + boot-logo), probes the save chip (FLASH via JEDEC, EEPROM via wrap-detection), dumps the save with cart-swap detection at start and end. Protocol ported from github.com/kitlith/powerslaves (MIT). - Shared DS system (src/lib/systems/nds/) — header parsing with CRC-16/MODBUS validation, maker/licensee code lookup (derived from devkitPro/ndstool, GPL-3.0), and a save-only system handler with generic dump-quality sanity checks. - Scanner UI (src/components/wizard/nds-scanner.tsx, src/hooks/use-nds-scanner.ts) — polls for a cart, displays detected game info enriched with No-Intro lookup by serial, runs the dump, and surfaces hashes + .sav download. - Wiring — App.tsx routes nds_save devices to the new scanner; use-connection.ts adds a connect/reconnect path for the device's WebHID filter; devices.ts registers the device. Adjacent changes: - nointro.ts — add nds_save No-Intro system mapping; prefer retail entries over (Beta)/(Proto)/(Demo)/(Sample)/(Unl) tags when multiple entries share a serial, so lookupBySerial returns the cart users actually have. - hashing.ts — formatBytes now scales to MB for ROM-size displays. - types.ts — declare "nds_save" as a known SystemId. Sources cited in THIRD-PARTY-LICENSES: kitlith/powerslaves and devkitPro/ndstool. The README's supported-hardware table and license attribution list are updated accordingly.
