Top Compression Formats for AetherSX2
Selecting the right format is critical for balancing storage savings with gameplay performance.
CHD (Compressed Hunks of Data): Widely considered the "Gold Standard" for AetherSX2. It provides excellent lossless compression and is faster to load than other formats.
CSO (Compressed ISO): Originally popular for PSP, this format is also supported by AetherSX2. It is efficient at removing "junk" or empty data blocks from the original disc image.
