Well I've just started playing my GTA: Liberty City Stories.cso and it runs soo dam slow. Not game-breaking slow but really annoying slow. I've been trying to decompress it back into a ISO file but all the converters I've tried made it into a iso file but it was even smaller than the original CSO file!

So i was wondering if you guys knew any CSO decompressors that actually worked?..

Tried that one but i tried the 1.3 version, may as well give it a shot.

EDIT: Nope, It still converts it to ISO and is only 168mb

It sounds like you probably grabbed some ripped version and will have to redownload. And in any case there is no conversion to be made--you could simply extract all the files then add them into umdgen and save an iso and it would be playable.

not UMDgen, it isnt reliable.

i use a good one called "Yacc"
How is UMDGen unreliable?
I decompressed alot of my CSOs,and they are always worse than they were before.

Hmmm, Ill have to remeber this from now on. I've never used UMDGen for decompressing but I'll take that into consideration next time.

Why? Because somebody on the internet said so without anything to back it up?

Well, if you think its so safe how about YOU do the decompressing?

Lol chill guys I'll just try YACC no need to argue which is better

So with that program, i should just be able to extract the cso and then rebuild it as a iso?

Btw with my cso, it has the music ripped from it

I've used YACC, PSP compressor, and UMDgen to compress and decompress all my ISOs. I have been using those for about 2 years now (or at least back when OFW 3.50 came out). I never had any problems.

YACC should only compress/decompress the CSO as far as I know. UMDgen is what you need to extract/make an ISO.
Pretty sure that's why it's 168 MB. The music file is pretty big. I think it's nice since the original ISO is ~1GB, and you can use the ripped space for your own music instead.

Sorry for the double post. I'm used to an forum that does an automerged double-post thing.

Isn't that what I said the first time? 'you could simply extract all the files then add them into umdgen and save an iso and it would be playable'

It's not an issue of which is better. It's whether you want to have two programs to perform the same function when one of them does this and more. Also with people accusing umdgen of somehow being unreliable when its functionality depends on reading and writing iso and cso, and it does both.

You dont even need to "Extract" all the files, you can just open up the CSO and then choose save as .ISO.
