Whats the difference between ISO and CSO???

CSO is simply compressed ISO.
So CSO files will be smaller than ISO files, but you may experience slowdowns when you play a CSO.

.DAX is also a compressed ISO file, made by the king, Dark_AleX.

DAX is smaller and loads faster than CSO, but CSO works with wifi.

So if I get a DAX or CSO, I dont need to worry about compressing it as it already is??

Exactly.

Though you might need to worry about being able to play DAX, as you need a plugin for DevHook to play DAX.

I dont have any DAX yey, so Ill worry about dat when da time comes....

Thanks much...

Duz DAX mean:

DArk AleX

With the capitols DAX, not there are two A;s so it could be either one..

lol no it doesnt hah your funny

You sure?

I always thought that DAX did stand for Dark_AleX.

What duz it stand for??

PS, How do you get ISO and compress it to CSO???

use this umdgen 3.5

THat;s like DVD shrink for ISO??

I would say that it is more like WinISO for PSP, or Nero (but instead of burn to CD/DVD, save to ISO).

And the compressor it uses is lossless (like a ZIP or a RAR file), as opposed to DVD Shrink which loses quality on compression.

Can you do losely??

PS DVD Shrink takes a really long tiome on my PC 4-7 Hours, duz this one take that long too?


PS Duz CSO let you use multiplayer, I have CSO of NFS Carbon and I cant play my brother and he has the actaul UMD, are the different versions??? What about DAX, duz that one let you use WLAN to play?? Someone said b-4 that one can and one cant, I dunno which one..

By "losely" do you mean "lossy"?
You can't compress PSP ISOs in the same way that you can compress video because you would lose important data and the game wouldn't run.
It is possible to compress the video and audio of the game in some cases, but it's usually more trouble than it's worth.

Converting ISO to CSO doesn't take that long; nowhere near 4-7 hours, closer to 4-7 minutes.
And you should be able to use multiplayer with CSO (it's no different to ISO in that respect), just make sure the WLAN switch is up and that you're not running at 333 MHz.

HOw long duz it take you to use DDV shrink, maybe DVDs take forever sicne they reduce quality and the CPU had to remaster it, but ISOs are just binary data and it desont have to covnert to video then back again.....

Also so Dax is the one that desont have multiplayer??

I haven't use DVD Shrink for a while, but when I convert videos it normally takes just under the actual duration of the video to convert (for a single pass). So if the video is 2 hours long, it will take around 2 hours to convert. Then it takes around 15 minutes to burn to DVD (at 4x).

And I thought all ISOs (including DAX) work with multiplayer (although I don't actually have any DAX ISOs to try it out).

While we're on the topic of ISOs, Uncle Jam (the writer of the DAX plugin for DevHook) has released a new version with JSO support (a new ISO format):
http://forums.maxconsole.net/showthread.php?t=35690
It's meant to be an improvement on CSO in both filesize and memory required for the PSP to decompress it.
But I haven't used that yet either.

Ill have to try it out...

PS What's yur CPU speed?

cpu speed should start at 222mhz so it won't freeze when u boot into 1.5 and u can change the speed to anything u like (also u might see some wifi errors when anything is higher than 222mhz and i believe anything lower will cause problems too)

and i though DAX did stand for Dark_AleX

when i use dvd shrink it takes about 10 or 15 mins for a 2 hour movie. but thats probably because i have 4gb of ram and a HUGE processor.

Whats the CPU speed, I mean of both yur computers!! PS I though DAX meant dark alex too.

My CPU is an AMD Athlon XP 2800+ (so it's equivalent to 2.8GHz).

THat's 10 times afster than mine

I'm not surprised that it takes 4-7 hours to run DVD Shrink then.
But I suppose if you just leave it going overnight or in the day while you're at school then it doesn't really matter (that's what I do for large downloads).

DVD shrink takes long time, but ISOs take less right??

Yeah, I need a new computer, I hear my sisters friend has one maybe I can take it...

Yes, PSP ISOs take much less time.

Ill try it, havent got around to it but ill try...

Does a CSO file lose some quality or loading speed compared to an ISO?

some games can be laggy when compressed into .cso
usally newer ones get pretty laggy/glitchy

CSO files don't lose any quality, you can decompress them back to the original ISO.

As quikadanquik has said, they can lag a bit though compared to ISO.
However, if you set the CPU speed if your PSP to 333 MHz they generally run OK.

So its losless so can can bring it back to ISO [except for parts that got cut out!], and if I set it to 333Mhz it'll lag less???

Yes, you can bring CSO back to ISO (and since it's lossless no parts will get cut out).
And yes, if you set it to 333 MHz it will lag less (most of the time it won't lag at all).

I still get lags but I think heres how it foes:

The small lags are gone,
the big lags are small lags.

Also I used UMD Gen and it took 3 hours, but anyways, the CSO didnt work!! Here's what I did:

Remove padding [Turn off or whatever]
Checked for dummy files [There were none]
Converted to CSO

When I start it it says, "The Game cannont be started 800xxxxx" xxxxx is some number, so U need it?? I ran CSO before, but when I did my own it didnt work!! What did I do wrong???

About the lags, it depends on the game really, for example; GTA tends to lag a lot (better to leave it as ISO).

UMDGen shouldn't take 3 hours... that might be part of the problem.
Try using PSP ISO Compressor (v1.4): http://www.psp-hacks.com/file/900
And I have no idea what those numbers (800 etc.) mean anyway.

Ill try http://www.psp-hacks.com/file/900, thanks, about the 800 errors, is it safe to remove padding??

The padding should be compressed out using PSP ISO Compressor.
But normally it is safe to remove padding.

Maybe I'll try using some, like an LBA of 1 just to be safe.... Any1 know why it f@#$ed??

Have you tried not touching the ISO with UMDGen and just putting it straight into PSP ISO Compressor?

I havent got around to downloading it yet..

Will it be faster?? Will it work beter??

Also, I still have the working ISOs from my dumper, I always will, just in case....

It probably won't be much faster.
It should work better.
And it's always a good idea to keep the original ISO until you've tested the CSO.

Even after I test the CSO, just incase I wannt access stuff I took outta the CSO, I wont have it on my MS, probably burned the a DVD-R, I may use USB hosts if they are what I think they are.. [ http://www.psp-spot.com/forums/index.php?showtopic=30497 ]

PS I may be getting a new PC!:

i use 7zip to stor the iso

I use 7zip manager but I dont thin u can use the 7zip plugin cuz Dev wont read it...

the diff is the size

i think CSO is just a compressed iso?

I have a Pentium 3 667!! See my sig!!

hey man...dax is able to multiplayer...mine does...dont worry abt the file format...devhook plays iso n cso but with plugin,it plays dax,cso n iso..mine plays all 3 format except on emulated 3.02..
need not worry abt format,cz therez a converter in this site,it converts between iso,dax,cso n jiso...but i think dax is smaller...but not compatible without plugin...

all my games is in dax,save my hd space,when i wana play in my emulated 3.02,i juz convert...
anyways,iso in ms dont need any LBA spaces between files...the LBA sizes juz for umd,itz to load slower,the reason is unknown,but w/o any spaces in between for the psp to read,it skips the spaces n loads the next file...that makes it faster..n also save some disk space...

abt which format loads faster,i dont know,i prefer to save disk space on my ms...haha

WOw so u get smaller file sizes and free games!! Why would sony make iot slow?? If anything they need to make it faster!!

CSO is smaller but sometimes the game is crap

I havent noticed a speed issue with cso. definately worth it to save the space
