In the Dreamcast scene, (often abbreviated as “HQ” or “EQ”) refers to a set of technical practices that minimise the amount of data that must be discarded when compressing a 1GB GD‑ROM into a 700MB CDI. The following techniques are the hallmarks of a high‑quality release:

High-quality CDI builders optimize the Logical Block Addressing (LBA). By placing frequently accessed data on the outer edges of the CD-R, they reduce the strain on your Dreamcast’s physical laser lens, resulting in faster load times and quieter console operation.
