[QUOTE="WiiPower, post: 3076800, member: 139019"] Wiimm do you know how the game loading works in CFG? I mean with the offset list and stuff. I think you should find the smallest format that: 1. Contains all data the scrubbed image contains, and extracting and/or converting it results in a 100% match to the scrubbed image. 2. Can be read by usb loaders, or to be precise by the cIOS modules of them. This could be used for storage and game loading. A solution with good compression for storage is nice, but if you need another format for gaming, you need your games 2x, and the advantage is lost. Removing the hashes and using decrypted images should work for both. But what about an easy(implementable with VERY FEW code) compression that allows random access of the .isos? You were speaking of 2 MB chunks, is that the smallest that can be used? I think 2 MB is still too big to be usable from within the cIOS. Or wouldn't that mean if data was at offset 1.8MB of a 2MB chunk, that the cIOS needs to read the whole 2MB, then decompress it, and then it can return the 0.2 MB? PS: Sorry for expecting so much from you, but you seem to be the only one working on anything in that direction PPS: If you find such a format, i'm sure we can convince team CFG to implement it in CFG [/QUOTE]
