CHD (Compressed Hunks of Data): Currently considered the gold standard for disc-based games. It uses lossless compression to remove "padding" (empty space on the original disc).
CSO (Compressed ISO): A format originally designed for PSP that also works for PS2. Tools like MaxCSO are commonly used for this conversion.
