Always used 9, never noticed any lag on any games, GTA:LCS doesn't lag because I bought the UMD just for the 2.50 2.60 exploit (who remembers those days?) so I don't really play it but man! the loading times are looooong.

I remember the good ol' DevHook days.

I use 9. I wish GEN would some how use some of the higher compression types like the ones used in 7-Zip.

I try not to compress my iso's into cso's. No reason why really...Just like to keep them in the most native/original format as possible. However, the few times I have used UMDGEN to compress I used 9.

yup i use 9, sometimes though it can damage the game because it s been compressed to much. eg resistance retribution took like 5 mins to load. i uncompressed it and it then started loading instantly

You can make one. Just make sure the compression tool uses the .DLL for 7-Zip and not ZLib.

ive noticed that some games lags on a class a memstick with cso format than in original memstick that has 9 level compression in 5.00m33-6. I've played GTA LCS and GTA VC in my orig 8gb and setting the ms speed access to always and i play it with no lag with a cso format.

but on 5.50gen, it really lags because of lack of ms speed access feature, so i decompress again GTA to iso to avoid lags

NCAA 10 lags really badly in CSO. You can see the FPS go down at certain points of the game especially kick off.

You know how much it'll lag? UMDs will be considered heaven compared to 7z.

EDIT: Does the PSP even have enough memory it extract 7z?

Funny, actually I made this thread as I was planning to do this myself, since I already have sorted the API for rcomage (rcomage uses 7-Zip for deflation, which is why RCOs compressed with rcomage will generally be smaller than other tools), so making one wouldn't be that difficult. CSO is a fairly simple format.
Also had some other things in mind. Currently the best tool is CisoPlus? Only advantages it seems to have over standard ciso is NC support, support for two threads and ripping capabilities.

Most of the CISO tools I've seen statically link against zlib.

Referring to 7-Zip's implementation of deflate, not LZMA. 7-Zip's deflate tends to compress better than zlib.
It's the basis behind tools such as AdvanceCOMP.

Have no idea how good it is though.
