FUNCTION DEFINITIONS ***********************/

Hardware CRC32 on ARMv8. devkitA64 builds with -march=armv8-a+crc, so the checksum is effectively free instead of a bytewise table loop.

validPin mirrors Transfer::validPin on the console: exactly 4 ASCII digits.

Send a single raw SPI command frame at 512KHz (one chip-select assertion).

Shelf-pack a w x h glyph into the newest atlas page (older pages are closed), opening a new page when full.

saves() always carries a synthetic leading "New..." entry (see Title::refreshDirectories), so the real backup count is one less.

Real backups only, i.e. excluding the synthetic "New..." entry (index 0) and the optional "Receive" action row (used for the "BACKUPS · N" header).

The date-stamped folder name suggested for a new backup. Account saves also append the (ASCII-folded) user name; the special save kinds use the bare d

Bind the shaders + vertex stream for `mode` (only when it differs from what is already bound on the cmdbuf).

Some titles (notably malformed VC injects) don't null-terminate SMDH title fields; reading them as raw char16_t* would run past the fixed-size array i

cellName takes a *cell* index (into the title's saves list), not a display row — callers translate a selected row with rowToCell() first.

FC's face choice: NintendoExt owns the PUA block (button glyphs), then the Standard font, then the CJK fallbacks (BMP only, as in SDL_FontCache); anyt

Copies a UTF-8 string into a fixed field of `fieldLen` bytes, always leaving room for a terminating NUL. The SMDH short/long descriptions are 0x40/0x8
