Comprehensive List of Natively Supported Compression Formats

Recommended Posts

I think I'm going to use CSO for my PS2 games. It compresses so much faster then GZ.

 

Does anyone know if it is possible to decompress CSO back to ISO? If so how?

 

Edit: Since it appears MaxCSO can't decompress from CSO to ISO (If anyone knows how to please post!), I found something that can. Was able to do it with CSOMultiCompressor!

Only tested with one game (ATV off-road fury 4) and I was able to play it without any issues after decompressing from CSO to ISO with this

 

It can, you have to use the command line: maxcso --decompress input.cso -o output.iso

There's a hint I totally forgot to tell you guys, if you have NEO GEO CD isos there, you can shrink your CDs set down to 5GB, Raine emulates NEO GEO CD really good and it has some interesting features, it will play your game if they are in ISO+WAV or Zip+Mp3, so that's what I figured out, this picture shows the size of the whole NEO GEO CD set, including Samurai Showdown RPG:

Here's an example of what one of NEO GEO CD games look like, the ISO content is extracted and then zipped, the WAV files are converted to MP3, if you convert them to 320 Kbp/s you'll still have a high quality soundtrack, but the resulting size is tremendously smaller, in my case, I converted most to 128 kbp/s and they all play with a nice quality:

Raine will load the zip file as any other rom:

One of the things that was a down point in NEO GEO CD console, is that it had long load times compared to the cart AES console, but Raine has options to turn off completely the loading screen, it will run the game as the cart AES console, but it will have the high quality songs and soundtrack, which is a must for NEO GEO lovers, KOF games, Samurai Showdown games have a different experience when compared to the Arcade/Console AES versions as the NEO GEO CD, Sega Saturn and Playstation used real instruments to play most of the songs, in my case I put the loading screen to 32X because I like seeing, at least for 2 seconds the artwork they put in between the battles, even in 32X it's like it doesn't load the game at all, it's seems more like a quick fade screen than anything.

If you have NEO GEO CD and wants to save over 50 GBs without removing anything from your HDD, you should consider this.

 

Hope it helps.

Hey, sorry for the weekend delay guys.

I updated the main post with some of the information we've seen here. I'll have to add the files later that were posted on, I can't download things at work.

That GDI to CHD compression is amazing. I went from 78gb to 34gb.
I still need to try out a batch process for converting PSP to CSO. I discovered I have not converted all of those by a long-shot.

Regarding Neo Geo CD, you mentioned converting .wav to mp3? How does one go about doing that?

I've yet to integrate any of the NGCD games into my system yet. I'm hesitant to do so as you describe some of them provide a different experience like Samurai Shodown (I'm trying my best to avoid censorship of that series)

I know it had Samurai Shodown RPG and Crossed Swords 2 as exclusives though so I do want to get those implemented. I've seen translations of Crossed Swords 2 on youtube, but never found the patch or translated game.

Samurai Shodown RPG I am unsure if a translation was ever made.

Yeah, you have true instruments, providing a different experience, I like NEO GEO CD games better because of that:

The Samurai Shodown series had some notorious censorship of blood and gore through (many) various ports and re-releases. I'm not sure if that affected the Neo-Geo CD at all, but I know the original MVS/AES copies are uncensored.

Noooooo no no no no nooooo lol hahaha

I never have a fullset for anything. Nope, haha. This is just for my personal collection, and what I have thus far. That's like 30-ish games I think? I'm still working on that system.

Still though, that cut my file-size in half, so the compression rate is incredible.

Once I set the .chd extension in RocketLauncher it just booted right up like normal.
Same thing worked for the Reicast core in RetroArch.

I'm not sure if it works with Demul though... I'd have to check the notes. I think it does.

I don't have Demul setup though. Not sure about Chankast either.

I need something new though lol Street Fighter 2X, Super doesn't run more than 2fps in NullDC for me. I can't get Reicast to play Japanese games at all either.

Can nulldc play Chd? If so, how?

 

Yes it can, you shouldn't have to do anything to make it work. NullDC supports it natively and I think chd is listed as an extension in RLUI for that module by default. If not, you would just have to add chd to the list of extensions.

the img reader plugin in just gives me an error. I think I may have the wrong plug in as it doesn't list chd as an available format

Make sure you're using the nullDC SVN 150 build from March 10th, 2013, since CHD support was added to it around then.

Is anyone aware of any kind of Saturn compression?

I have all my games in Bin/Cue at the moment.

Wouldn't be surprised if nothing existed, given the poor state (Although better than XBOX ...>.>...) of it's emulation.

Saturn is one of the few remaining systems that still need an image mounted. Therefore dtlite would also have to support the same compression. Don't see that happening anytime soon.

It's an off-topic comment, but it seems you're not aware how SSF emulation is good, it doesn't use any plugins, it's a solid emulator, I can play basically all games in it without any frame drop or any kind of issues I could remember.

It lacks some modern features for modern monitors, to make it look smoother, yeah, but if you run it with scan-lines or in a real CRT monitor it's otherwise perfect, what makes it even more amazing is that it was Shima, one Japanese guy only who developed this emulator, he deserves all credit and thanks from us since we can play 99% of Saturn games like in the real hardware thanks to his effort and unique ability to achieve what everyone else haven't so far.

That's a solid point, hadn't thought of that.

Yabuse core in RA is up and coming though, so maybe in the future something will pop up.

Yeah, SSF's actual 'emulation' is pretty good. You have to give it that. Far more impressive compared to any other SSF emulator that's for sure. I just hate the actual program. It makes sense being made by only one guy that it is the way it is. The fact that Yabuse is in second and is SO far behind is more to my point though. Anyway, you're right though this isn't really the point hahaha.

I just amassed a ton of Saturn games and thought I'd see if there was a compression method that fit our discussion.

There's two options for a compression in Saturn Bins/Isos, the first that comes to mind is the 7z, it will give you the undesired loading time, the second, less effective in terms of compression would be using the NTFS compression that Windows offers as a way to save some space.

 

Actually these methods would work also for all other CD systems that doesn't have a compression that is supported by their emulators.

 

You can add these info in the first post as additional methods to save space for cases like these.

At some point I will point towards 7z compression and stuff, once we've covered these native formats a little more thoroughly.

This NTFS compression though, I've heard a little about this... How does this affect read/write speed, hard drive life, and more importantly, Fat32 isn't very common anymore, right??

You'll find more info about NTFS compression here:

FAT32 is very common, for Pen Drives, SD cards and so on, HDDs use NTFS system.

There is new information regarding the file length problem on the Wii system:

you can simply merge the two files Backup-Manager generates with a binary copy to one single file. It works flawlessly then. (it's possibly the Linux file system on the real Wii which causes this process, otherwise it won't run there).

 

I have experienced one game where the two files were exceptionally large. I think it was a problem with Backup Manager. In all other cases the merging process went well. So it is possible to generate a WBFS-only collection.

This is interesting I'll have to check it out.

I guess I kinda got distracted doing so much and haven't updated this in a bit... lol

I actually couldn't for the life of me figure out how to use Dolphin to do WBFS, so I put them ALL (Gamecube and Wii) into gcz.

I keep seeing that format knocked, but it cut 3.5 gigs off of one of my games, so it's A-OK in my book.

I also upgraded to a 3TB the other day (Had to do an entire backup) so space isn't as bad of an issue as it was lol Still, the fact I've probably cut 1/3rd away from my overall filesize is nothing to dismiss.

You can't! Dolphin only can convert to GCZ. You have to use BackupManager.

WBFS easily cuts off another 20% (my guess). I will take this road.

... I swear we had discussed it 'could' at some point, but it seems that it can't by your testimony, my experience, and more searches online.

I updated the front page to reflect this 'revelation' lol
