Highly compressed 3DS games are essentially retail game dumps or backups that have undergone specialized compression techniques to reduce their file size for storage or easier distribution. This process typically involves removing "padding" data (dummy data used to fill up cartridge space) or using seekable algorithms that allow emulators to read the data without needing to fully extract it first.
