What Fixed-width Bit Rotator does
Rotate an unsigned fixed-width integer left or right while wrapping bits that cross the selected boundary.
Input and output contract
Widths from 8 to 256 bits are supported; rotation counts are normalized modulo the selected width. A width-padded uppercase hexadecimal value.
Safe workflow
Choose width, direction, and rotation count before processing the hexadecimal integer. SaveEditor processes this operation locally in the browser and does not infer a game format from the input.
Important limitations
Rotation is not the same as logical shifting because wrapped bits re-enter on the opposite side. If a format rotates individual bytes instead of the whole integer, use the File Bit Rotator for per-byte operations.
