I use the Win7 “Compress contents…” to compress the folder my Retroarch saves all the game states, but i’d like to ask if Retroarch is going to support native compressed save states (like 7z).
no plans at the moment. We’ve talked about compressing them internally using gz, for example, but there are no plans to support externally compressed savestates.
Internal compression (especially gz) is fine if implemented. No need for external compression then.
Save states take a lot of space if you have cores from N64 and above and more than a few games.
