SentaiBrad Posted March 29, 2016 Author Share Posted March 29, 2016 So yea, compressed all of my PS2 games (it took a while) as .cso's with maxcso and it saved me about 300-400GB? I remember it being about 1TB or so. So it's not as much as them being 7zipped or rared (not as big of a gap as you might think actually) and load times are not perceivably worse. I also don't have to deal with unzipping or raring each time I want to play the games too. I am hoping this becomes a thing for PS1 games too. cue sheets can point at any type of file technically speaking. Quote Link to comment Share on other sites More sharing options...
niglurion Posted March 29, 2016 Share Posted March 29, 2016 Ah good to know! I've compressed all my GC and Wii games as CSO/GCZ and WBFS, it took a while too, but around 200go saved. Didn't know CSOs work for PCSX2. I think I'm gonna compress all my games in this format, thanks to you . For PS1, I'm using PBP files. But like you, I don't like the zipping process. I don't like doing that when it affects performance. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted March 29, 2016 Author Share Posted March 29, 2016 You could actually use YACC (Yet another CSO compressor) that you use for PSP games on PS2 games, but they don't support large discs (4.8GB+). maxcso was written by some of the PCSX2 devs and supports everything. I had corrupted trying to convert some of my bin games to iso, but once I re-downloaded them and converted them properly (use MagicIso to open the bin and literally just "saved as" with the game name.iso) and then put iso in the name of maxcso and dropped the exe in to my PS2 games folder, I searched "iso" in the Windows search so it would open all my sub folders, then put that in to list view and sorted it by size. So maxcso was at the top with the smallest games first, and I just compressed a bunch at a time. I only ever did 3-4 at a time because it eats CPU and my work (LaunchBox and YouTube) requires my PC.

DOS76 Posted March 29, 2016 Share Posted March 29, 2016 WOW! I have an insane PS2 library at around 3.58 TBs so this could probably save me an insane amount of space. Did you test the new files and make sure they worked. Quote Link to comment Share on other sites More sharing options...

Did you test the new files and make sure they worked. I only tested a few, but yea they work. Load times don't seem to take much longer either, if at all.

DOS76 Posted March 29, 2016 Share Posted March 29, 2016 You weren't kidding about that being a processor heavy operation its got my 4700 running at 100% Quote Link to comment Share on other sites More sharing options...
Drybonz Posted March 29, 2016 Share Posted March 29, 2016 It took most of a day when I did mine and I only have about 100 games. Quote Link to comment Share on other sites More sharing options...
niglurion Posted March 29, 2016 Share Posted March 29, 2016 lol, yea, the processor is always at 100%. High temp' power! A screenshot in order to see the difference between .cso and .iso (before I delete .iso). Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted March 29, 2016 Author Share Posted March 29, 2016 Yea sometimes the savings are great, sometimes they're a bit on the smaller side. It'd be kind of the same with 7zip or WinRar, the games that can be compressed more will still have the biggest %'s taken off. The beauty about maxcso though is if a game doesn't play right you can uncompress it by dragging the cso back on to maxcso and it should go back to an iso.

DOS76 Posted March 29, 2016 Share Posted March 29, 2016 Thanks for that Brad that is some useful information there. I was afraid to delete any iso's I hadn't tested first but now I see that that isn't a concern. Quote Link to comment Share on other sites More sharing options...
niglurion Posted March 30, 2016 Share Posted March 30, 2016 Is there an easy way to change files extensions for an entire plateform in launchbox ? After being compressed, it's really boring to change manually and one by one every file extension for every game in Launchbox (ctrl+e > change name.iso by name.cso > ok > repeat).

DOS76 Posted March 30, 2016 Share Posted March 30, 2016 Not that I know of. You can just change them on a need to basis or completely remove them and import your new files all of your data and images would be associated with the new file without having to download them again as long as you don't delete the folders.

niglurion Posted March 30, 2016 Share Posted March 30, 2016 Ah yes, I didn't think of that! Good idea. Thank you. Quote Link to comment Share on other sites More sharing options...
SentaiBrad Posted March 30, 2016 Author Share Posted March 30, 2016 Yea, images and video are tied to the game name, not the file extension. Quote Link to comment Share on other sites More sharing options...

DOS76 Posted April 18, 2016 Share Posted April 18, 2016 I did but I got distracted and stopped working on it I'll have to get around to doing it again. Quote Link to comment Share on other sites More sharing options...
fromlostdays Posted April 19, 2016 Share Posted April 19, 2016 Here's a guide, apparently you can compress/trim/all around reduce the size of PSX, DS, even GBA. https://www.reddit.com/r/emulation/comments/3g933n/guide_reduce_the_size_of_your_ps2_gc_wii_x360_ds/ I'll be testing some of this out in the near future as I filled up my 4tb external just recently.
